Programming languages used to develop iOS apps
Swift vs Objective C
With the introduction of Swift, iOS mobile app developers are torn on whether to adopt Swift or stick to the stable Objective C.Swift vs Objective C is an ongoing dilemma among developers. Every ios app developer desires a programming language for that is easier to learn, stable, has a simple syntax, secure, and has a helpful compiler.
Bearing that in mind, now let ’s discuss which programming languages you should adopt to build your mobile app.
Apple affirms that Swift is 2.6 times faster than Objective-C . Whereas this might be true, the difference in performance can be attributed to several factors.
First, you should understand that, Objective-C because it is naturally not fast.
Let me explain why. Objective-C utilizes the runtime code compilation instead of the compile time. This means that there is an extra loop involved during compilation while using Objective-C.
What do I mean by an extra loop? Every time Objective-C object calls another object during compilation, and the extra loop introduces an extra level of indirection.
On the other hand, Swift is generally made to be swift. Data from several tests suggest that the performance of FFL algorithms is at par with C++. However, in the Mandelbrot algorithm, Swiftui app performs better than C++.
Swift is an upgrade of Objective-C, and its main purpose was to eliminate drawbacks found in C++.
Therefore, Swift was naturally meant to enhance safety for iOS products. First, Swift prevents errors as a result of type-safe and memory-safe language.
What do I mean by this? Swift helps to prevent memory safety by avoiding vulnerabilities associated with dangling pointers. Swift does not use pointers, and in case you fail to find a pointer, the app mainly crashes. Lack of pointers in Swift helps programmers to fix bugs quickly and keep the code clean, making it easier to understand.
On the other hand, Objective-C uses pointers that can induce vulnerabilities in your app. In Objective-C, when you miss a pointer when calling a method, nothing happens. This means that the code will execute error-free but with vulnerabilities. The expression and line of code in the object becomes a no-operation (NOP). A NOP is a dangerous situation because it makes it difficult for programmers to find and fix bugs.
Maintaining files in Objective-C is pure stress. As a mobile app developer, you must maintain two separate files of code to enhance efficiency and reduce the application development time. Developers must also synchronize the method names and comments manually.
On the other hand, Swift is a darling for an iOS developer because its easier to maintain. Swift uses the LLVM compiler and Xmind to accomplish the incremental build automatically. This means that the Objective C header (.h) file and implementation (.m) file are combined automatically in a single .swift program code file.
When developing Swift, Apple’s main goal was to provide developers with a simple and easily understandable programming language for iOS development. Swift adopts all industry standards to help developers write clean code easily.
Objective C is built on the C programming language, and as a result, it has a very complex structure. First, it has a lot of @ symbols, lines, semicolons, and parentheses while using else statements.
On the other hand, Swift has a simple syntax that resembles English. Swift requires iPhone app developers to substitute @ with a comma to separate a list of parameters. Developers who use Swift write a few lines of code compared to Objective C for the same application.
Objective C requires developers to use a lot of strings when linking different pieces of information. As a mobile app developer, you also get a headache while using special tokens like %s, %d, %@, and use commas to separate variables.
Any wrong usage of a symbol or ordering of a list of variables can cause your application to crash.
Swift, on the other hand, requires less code while implementing loop statements and handling strings. When using Swift, developers do not need to memorize tokens because Swift employs string interpolation. Interpolation helps to eliminate common app crashes, as evident in Objective C.
Both Objective C and Swift employ ARC that helps to manage memory without any programmer effort. However, in Objective C, the code is not supported by procedural C or other crucial APIs like core graphics.
As a result, Objective C has extensive memory leaks that hinder efficient memory management.
Swift also employs ARC. Unlike Objective C, Swift supports ARC for all APIs facilitating efficient memory management, just like with Cocoa Touch.
Swift ensures that the ERC is complete with the object-oriented code paths saving iOS developer's time.
Dynamic libraries support
Dynamic libraries represent the executable parts of code. The main difference between dynamic and static libraries is that dynamic libraries can be linked to any code during run-time. One major issue with Objective C is that it uses static libraries and does not support dynamic libraries.
Let me tell you, this is a problem. Static libraries are large in size, mainly because external programs are built in the executable files. Dynamic libraries are smaller in size compared to static libraries because only a single copy of the dynamic library is stored in memory during run-time.
Swift supports dynamic libraries. The dynamic library is loaded into an application memory during run-time, which helps to enhance performance. Connecting the dynamic memory directly to the app ensures that they are updated independently from the Operating System.
The use of dynamic memory helps developers to reduce the size of the application and enhance the loading speed of the app contents.
Objective C was the main programming language for Apple products. The majority of programmers are reluctant to adopt Swift because they had invested a lot of time and resources in learning Objective C. Even though Apple seems to be encouraging new and existing programmers to learn Objective C, there are no signs to indicate that Apple will discontinue supporting Objective C.
Swift is a young programming language, and Apple has invested a lot to ensure its success. It is an upgrade of Objective C and currently has all the programming features lacking in Objective C. There is also an increasingly vibrant community that is supporting Swift. Recently, Swift started supporting the Linux environment indicating that Swift will become a popular language to develop iOS applications.
Currently, Swift has overtaken Objective C in terms of community support. According to a StackOverflow programming language survey, Swift is gaining traction quickly by Objective C programming and is still holding on to Objective C.
One main reason why programmers have not yet embraced Swift is that the opportunity cost involved in learning Swift outweighs the benefits achieved. Also, Swift is a young language, and veteran developers are waiting for apple to start using it on a large scale for them to shift.
Swift is open source, and as a result, it has attracted massive community support. The extensive feedback given on the forums helps Apple continuously fix bugs on time.
Which language is better?
As a programmer, it is difficult to determine which programming language for iPhone and iPad apps is better than the other. The main reason being it all depends on several considerations and factors.
As a result, you need to ask yourself the following questions.
- Which programming language does your team know?
- What is the project duration?
- Do you have the resources to hire new iOS developer?
- What are your current plans?
- How big is your project?
Answering those questions, among others, will help you decide which programming language to adopt.
Swift vs Python
The popularity of programming languages changes with time-based on their applicability and development of new languages. However, over the past few years, Python and Swift have proven to be a major force to reckon in the programming world. Their popularity and applicability have increased by leaps and bounds.
According to PYPL statistics, Swift is the second most growing programing language for developing iOS apps after Python.
Python was developed in 1991 and was meant to be used as a scripting language. However, more Python libraries were developed that allowed developers to use it for other purposes like machine learning, data science, and back-end development.
What many people don’t know is that Python can also be used to create mobile applications.
Historically, Python did not have an edge in developing mobile GUI applications. However, two frameworks: Kivy and Beeware have changed the narrative.
Before we discuss which is better between Python and Swift, let us discuss Kivy and Beeware briefly.
Kivy is an open-source Python library that allows developers to develop cross-platform GUI mobile apps. As a developer, you can use Kivy to create iOS and Android app.
Kivy does not allow developers to build native apps but provides custom inbuilt UI toolkit that provides UI elements such as forms, text boxes, and buttons among others. As a result, the UI widgets are not rendered using native platform UI controls. Kivy provides a good platform for developing games that are not too much UI centric.
The BeeWare project is a Python framework that allows developers to create native app.
The main difference between Kivy and BeeWare is that BeeWare employs the platform-specific native UI toolkit while Kivy uses a custom UI toolkit for developing android or iOS mobile application.
However, BeeWare is a new framework and therefore, there are constant API changes that increase a developer’s workload.
Python has more support from 3rd party libraries such as database compared to Swift. As a result, Python is better with back-end applications rather than front-end.
Swift creates more secure apps compared to Python. Swift employs type strictness. This means that the Swift compilers help developers to find bugs easily.
Python, on the other hand, does not employ type strictness during compilation. As a result, the create app might be vulnerable.
Swift is based on the C programming language. When creating Swift, Apple wanted a language that would be faster than C. Actually, Swift is 2.6x faster than C and 8.4x faster than Python.
Now, to the main question, between Python and Swift, which should you choose?
To be honest, Swift offers better-advanced features, functionalities, and support compared to Python.The fact that Swift is purposely meant for iOS application means that you can create better native apps compared to using Python.
However, the usage of Python in developing mobile apps might increase in the future with the emergence of Kivy and BeeWare frameworks. With its increased applicability in data mining and AI, developers might be thrilled to use one language to develop AI-related mobile apps.
Swift vs Java
Java has been in existence for years and has formed the basis for custom mobile app development. According to a survey, Java was ranked 20th while Swift was ranked 33rd among programming languages recommended for first learners.
Both Java and Swift are object oriented.
Java is not platform dependent. During compilation, Java codes are compiled into bytecodes that can run on any machine. This means that Java is a write-once, run-anywhere language.
On the other hand, Swift is dependent on iOS and MacOS.
In terms of security, Java enhances its security by using the Java runtime environment. Java is more secure compared to Swift. During Exception Handling in Java, the code does not crash but Exception handling in Swift can lead to crashing.
In terms of performance, Swift is faster compared to Java. To enhance its performance, Java uses the just-in-time compiler. Swift is built on the basis of the C programming language and thus faster than Java.
Swift best practices to ensure high-performance code
Naturally, Swift is built to be swift. However, every programmer desires the best performance. Therefore, there are a few ways you can use to enhance the performance of iPhone application development.
Use the build settings to adjust the optimization level
One strategy that iPhone app developers can use to enhance optimization when they develop iPad applications is by letting the Xcode optimize automatically.
The Xcode compiler is built in such a way that it can determine when to ignore irrelevant functions or directly call methods that were not subclassed. However, letting Xcode handle optimization increases the compilation time or the size of the solution.
So, how can you adjust the optimization settings? Go to build settings-> Apple Clang – code generation -> Optimization level.
The optimization level gives you seven options:
- None -O0
- Fast -O, O1
- Fast -O1
- Fastest -O3
- Fastest, Smallest -Os
- Fastest, Aggressive Optimizations -Ofast
- Fastest, Aggressive Size Optimizations -Oz
At this point, you can select the option that suits your programming needs.
However, most enterprise iPhone/iPad app developers optimize for speed for release builds, and others optimize for size during debugging.
Use Final and Private for Methods and Classes
The Swift Optimization level also deals with direct or indirect call methods. As an Object-Oriented language, Swift programmers can use Dynamic Dispatch to subclass and override methods to achieve more functionalities.
Dynamic Dispatch is an algorithm that uses the vTable (Virtual Table) to determine the method to be invoked anytime a message is sent to an object.
One crucial point you should note is that, during iPhone app development, when a developer calls a method to return to its address, the method must search the virtual table for its address.
At the same time, the Dynamic Dispatcher must also lookup for a subclass to confirm if the method has been overridden and return another method.
Since subclasses can also override methods, the Dynamic Dispatcher must lookup for the method iteratively until it gets to the bottom of it.
The Dynamic Dispatcher iterative process is a very expensive task.
To optimize this whole process, a Swift programmer can include the attribute final at the beginning of a method, variable, or a whole class.
Optimizing your Swift code using build settings guarantees that the final attribute executes a direct call without looking for subclass implementation.
Avoid Print in release builds
When developing mobile apps, printing to console helps in debugging. However, some developers leave the print commands floating in the code.
The print commands are mainly written on the console, which consumes large disk space, ultimately affecting performance.
After analysis, the above code with a print call ran 1600 times slower. Shocking, right?
Now, to avoid this, I suggest that you should never call print directly. But you use a class to wrap it and then include a class inside that class.
Inline your code
When programming, it is always crucial to subdivide your code into functions where each function handles a specific task.
However, creating multiple small functions affects performance. Performance is affected because the extra functions are added to the function stack. As a result, the virtual table uses the dynamic dispatch to call each function.
Therefore, to enhance your performance, you can squeeze your code and inline your method for faster performance.
However, when you inline your code, you must be ready to give up your clean code.
It is a trade-off between clean code and having better performance.
Dealing with Arrays
As a programmer, performance is critical when dealing with arrays. If not properly handled, arrays can induce performance issues. Now, here are a few ways that you can use arrays to optimize your code.
When iterating an array, use withUnsafeBufferPointer
At times during iPhone application development, programmers tend to forget or disregard memory issues or security issues because they assume Swift is handling everything. In the long run, these assumptions introduce performance cost.
One way that you enhance performance; though not an advisable way is to trade safety for performance.
This can be achieved by using the withUnsafeBufferPointer method to help programmers find the array of pointers for the array elements.
You should also be cautious because if the elements are deallocated, your code might crash when running it.
Generally, arrays use memory blocks to store their objects. As a result, whenever you add a new object into an array, it gets an unallocated memory block, allocates, and appends it to the array.
This strategy enhances performance but induces inefficiency during iteration.
We can overcome the iteration inefficiency by using ContogousArray.
ContagiousArray ensures that every item in an array is contagious with each other because contagious items assist in identifying the next element.
However, forcing items to be contagious introduces array management constraints.
Use a linked list instead of an Array
As a programmer, using arrays is always a simple task, but implementing linked lists brings more efficiency.
You should know that inserting an item in a linked list is simpler compared to an array because, in a linked list, all items are connected. In a linked list, you just need to connect the pointers properly and you are good to go.
Inserting or appending items in an array is more expensive than in a linked list. However, sorting items in an array is faster compared to linked lists.
Limit Protocols to Class Only if Possible
When your protocol is implemented through classes, ensure that you have marked it as a class.
Let me tell you why this is important.
Marking the class as a protocol informs the compiler that the implemented protocol is using classes only. As a result, the compiler optimizes the ARC (Automatic Reference Counting), which in turn improves your code performance.
During an app development process, you can solve performance issues by adjusting different app architecture techniques, caching, or using algorithms.
However, squeezing your Swift engine is a sure way of achieving optimal speed.
Tips and tricks to enhance iOS/iPhone app performance
There are several tips and tricks that you can use to improve the performance of the iOS app
Use a launch screen that looks like the initial screen
When a user opens an app, the launch screen appears first that is quickly followed by the Start screen. The change between the two screens must take minimal time so that it does not give the user the impression that the app is slow.
When designing the launch screen, make sure it is almost identical to the first screen of the app. when the two are loading, it gives the user an impression that the app launches quickly and is ready to use. The user perceives the app to be very responsive.
When you have a launch screen that looks different from the first screen, the user will experience the unpleasant change from one screen to another. The user will notice the time taken to change from one screen to another and conclude that the app is not very responsive.
You should not use the launch screen for any artistic expression, but it should solely enhance the perception that the app launches quickly and is ready to use. Also, you should not put any text or use the launch screen for loading or advertisement purposes as it may give the user a feeling that the solution is slow.
Sometimes when using a multitasking screen, upon resuming the app, it shows a different screen from the one in the multitasking view. This means that state restoration has not been implemented in the app. The data displayed in the multitasking view was lost when the app was terminated in the background and could not restore to the state the user left it in. When this happens, the user perceives that the iPad app is slow and unresponsive.
State preservation and restoration
Apps installed on devices such as iPhones and iPads are often interrupted by messages, calls, and alarms, among others. Your app should restore to the state the user had left it. In some cases, like where there is a shortage of memory, the operating system might remove the app from memory, making it lose track of the last UI state. In such a case, your app should be able to preserve the last state to avoid losing the user's progress.
When the user is multitasking, they see the other apps placed in the background. The user assumes that the apps are running in the background, but in the real sense, they might be terminated to free up some resources. Those apps take a snapshot of the last state the user left them in, and that what the user sees first and assumes that the app is still running.
You should employ this trick when you develop iOS apps. iOS device supports the use of screenshots to give the user the impression that the app is still running in the background, whereas it has been killed or restarted.
You should use UIkit as it preserves the state of the app and view controllers, and saves them in an encrypted file stored on the disk. When the user resumes an app, the UIKit reconstructs the views and view controllers using the data that was stored on the drive.
Use opaque views
Opaque views are not transparent, meaning that they do not allow the user to view any UI elements placed behind them. Setting a view to opaque can either be done in the interface builder, as shown in the image below, or it can be coded.
You can code an opaque view using the isOpaque property of UI view as shown in the code below :
view.isOpaque = true
When you set a view to opaque, it makes the drawing system to optimize the drawing performance while rendering the screen.
If you use non-opaque views, the iOS platform will perform extra tasks of calculating what should be displayed behind the different layers of transparent views. With opaque views, the drawing system puts the current view in front and saves the iOS from performing the extra tasks of blending more layers behind the non-opaque one.
To check which layers the iOS simulator is blending, you go to Debug, then check the color blended layers option as shown below.
Some views will appear red and others green. The red view will be indicating a non-opaque view and that there are layers blended behind it. Green shows that the view is opaque and no layers blended behind it.
If transparent views have to be used, then limit the number of views highlighted in red. When you limit the views in red, you spare the iOS the work of blending the two layers. This optimizes the app performance. To reduce the red views, you change the code to white.
label.backgroundColor = UIColor.clear to label.backgroundColor = UIColor.white.
The use of opaque views makes a significant improvement in the performance of the app. When you set the UIView to opaque, you are instructing the drawing system to provide a solid background color.
You should recheck the view as the simulator may still show red in the image view, even after you set UIImageView. Typically, that occurs if the image used has an alpha channel. You should remove this alpha channel by using the preview app to duplicate the image (Shift ⇧ + Cmd ⌘ + S). The next step is to uncheck the “Alpha” box and then save.
Use Grand Central Dispatch (GCD)
Have you ever used an app that becomes unresponsive all at once? Sometimes the iPhone app becomes unresponsive to the user's touch input, and it hangs. This mostly happens when heavy tasks are running on the main thread.
UIKit only runs on the main thread, and therefore assigning any heavy processing to the main thread slows down the UI and may make it hang. The UIkit uses the main thread to capture the user input and produce output and draw the screen.
To make the app more responsive, you remove the heavy processing from the main thread and assign them to run on background threads. Such operations include heavy input/output operations, networking, and complex calculations.
In the main thread, UIKit tasks usually alternate with light tasks in small intervals. When a heavy task executes on the main thread, the UIKit has to wait for it to finish so that it can execute its tasks. This time is when the app acts as if it has hung.
The GCD will help you in moving the heavy tasks to the background. Basically, GCD is another name for the libdispatch library, which provides concurrency support by moving some tasks to the dispatch queues managed by iOS. These are codes for used for switching queues
Any other tasks that do not have to run synchronously and interact with the UIKit, is switched to the background threads. This ensures that the UI does not become unresponsive while waiting for other tasks to finish running on the main thread.
You should ensure that no UIKit tasks run on the background threads. Modifying the UIKit objects to run on the background thread leads to the UIKit updating appropriately and result in crashing.
Use Xcode Instruments to improve performance
Instruments is a powerful tool for analyzing performance and profiling. Instruments profile your app using different metrics such as CPU usage, file activity, and memory usage, among others.
The instruments will help you make the necessary changes to your app to improve performance.
iOS app development FAQs
How to build an iOS app on Windows?
iOS app development on the Windows platform is not possible, but there are ways around that, where you can use a Windows PC.
The reason why you cannot build IOS apps on Windows is that Xcode, the IDE used to design, develop, and deploy IOS apps, only runs on MacOS. However, you can still deploy, run, and test your iPad app directly from Windows using Microsoft's Xamarin.
There are several ways you can develop iOS apps on Windows Platform without having to buy a Mac.
Using a virtual machine and installing macOS on the Windows PC
This is the easiest way as you make use of a virtual machine, which creates an environment for a guest OS, macOS, to run on a host OS, Windows, as if it is running on the hardware. This is the virtualization process.
You will require a copy of a macOS installer or virtual image and a virtual machine such as VMWare or VirtualBox to carry out the virtualization process. First, you have to install the virtual machine on Windows OS. Then, you mount the macOS onto the virtual machine. From there, you can install Xcode on macOS to enable you to develop your iPhone app.
Rent a Mac
This is a cloud service where you use your Windows PC to rent a Mac on the cloud. You use the remote desktop connection (RDP) to access the Mac products in the cloud. Such services include MacinCloud and MacStadium, which you pay for every month. Once you log in to the Mac product of your choice, you can install Xcode and develop iOS app on Windows platform. Monthly charges range from 20 to 30 dollars.
Build a Hackintosh
A Hackintosh is a computer that runs on macOS. To build a Hackintosh, you need to install macOS as the bootable OS on your computer. In the case of a Windows PC, you could create a dual boot, and upon switching the PC, you select the OS that starts. This is a tricky process, and you have to be familiar with computer hardware and creating custom installations. Some hardware are not compatible with macOS.
Use Cross-platform Tools
How to make an iOS/iPhone app more user-friendly?
App users interact with the user interface (UI). Therefore, you should design the UI in a manner that gives the user a great experience. The iPhone app must have high performance to be able to deliver quick and consistent results. Here are the tips from iOS app development service providers to ensure more user-friendly mobile app.
- State value proposition
Your iPhone app should tell the users what it will do for them and how it will do it. This informs the user of what to expect and should be done on the onboarding process.
- Load swiftly
When the user launches the app, it should take minimum time to load, just a few seconds. The solution must be highly responsive especially to the touch input.
- Minimize the need to type
Users do not like typing on a phone screen due to its small size. Therefore you should ensure that there is little typing on the app. The form should be simple and short, and you should implement auto-complete wherever possible.
- Reduce cognitive load
Too much text could be in the form of questions or choices that increase the users' cognitive load, and that defeats the purpose. You can do this by using more graphics and less text to reduce the cognitive load.
- Easy and efficient navigation
The user should be able to accomplish their goal as fast as they can. Good navigation should have few barriers and be comprehensible so that the user does not get lost and end up in random pages.
