Apple launched Swift, a new programming language in 2014. This language can be used for mobile app development and has given iOS developers an alternative to the existing and age-old language that is Objective-C, an object-oriented superset of the C programming language that has been the core of iOS development thus far over the years. Swift has been designed from the ground up to be compatible with the existing iOS development tools- XCode, Objective-C, and the Cocoa framework- but because of its ease of use and improved features mean that it is quickly starting to replace Objective-C. In this article, we are going to explore some of the few reasons why you should get on-board with the Swift language for your next iOS app development (Swift vs Objective C) project if you haven’t already.

 

Swift is Faster, and easier, lets developers become more productive during work

Much of what OS X operating system is based on is developed and comes from the inherited technology that dates back to Apple’s humble beginnings, and OS X’s new components have all been based on the Objective-C that includes mobile apps. Objective-C strengths lie in its stronger graphical user interfaces and feature-rich frameworks. But when you compare it with the newer Swift language- it is a clunky one to write.

 

As the hardware and software of the iOS operating system has evolved over the years and improved with better memory and processors. Apple has been successful in developing a streamlined language that was far better suited for fast-paced app development, and also to solve and address some of the Objective-Cs disadvantages. By unloading some of the Baggage that comes with the 30+- year old language like C, Swift has been designed to make the iOS developer’s life easier and more productive.

 

Compatibility with the Cocoa Touch Framework as well as The Objective-C Language

Frameworks are nothing but libraries of coded modules that makes developing applications faster and much more streamlined for developers. The frameworks associated with Apple’s operating system are Cocoa(for OS X) and Cocoa Touch( For iOS). When the modules written in Objective-C language, Cocoa Touch becomes specifically designed and geared towards touch-based devices such as iPhones and iPads. So what should this mean for a newer language like Swift?

 

Swift is fully compatible with Objective-C and when it comes to developing apps in Cocoa Touch, for the mobile framework for iOS. It works along with Objective-C so that developers can interface with the two languages, create mixed-language apps, and it takes advantage of Cocoa Touch classes with Swift, and Swift classes with Objective-C. The interchangeable classes, design patterns, and APIs have thus made it easier for the developer to pick and choose.

 

Migrating code from Swift to Objective-C is easy too, and vice versa. Developers can take advantage of Swift’s advanced features by replacing chunks of app code written in Objective-C with Swift.

 

Swift designed from the ground up with the Cocoa Touch framework. You only need to set up a Swift development environment in XCode and then import Cocoa frameworks. 

 

Advantages of Swift:

 

1. Swift Runs Faster, almost as fast as C++, And with the newer versions of Xcode released in 2020, it is much faster than before.

2. Swift is easier to read and implement, and is easier to learn than Objective-C: Objective-C is over 30 years old now and that means that it has a more clunky syntax. Swift is able to streamline code and more closely resembles readable English, similar to C#, C++, JavaScript, Java, and Python. Developers experienced in these languages can easily pick up swift pretty quickly. Also Swift requires less code. Compared to Objective-C which is verbose when it comes to string manipulation, Swift employs string interpolation without the use of tokens or placeholders.

3. Unified files make code easier to maintain: Again, an age-old standard is holding the C language holds Objective-C back. This is the two file requirement. This means that programmers and developers need to update as well as maintain two separate files of code, compared to Swift, this becomes one. That means less work for programmers and developers, but this does not come at the cost of speed for the front end.

4. Better Compilers means a better coding experience for developers and programmers: Swift is built-in with a Low Level Virtual Machine(LLVM), this is a compiler that is used by languages like Scala, Ruby, Python, C# and Go. The LLVM becomes smarter and faster than previous C compilers. So more workload becomes transferred from the programmer to XCode and the compiler.

5. No pointer means Swift is more secure: Objective-C similar to C language makes use of pointers, a method that exposes values more directly to data. The problem with using pointers is that it makes and causes vulnerabilities in security. They also create a barrier for finding and fixing bugs. However using Swift, your code’s pointer is missing a value(a nil value) instead of continuing to run the app, it causes the app to crash and allows you to find and fix the bug on the spot. You will also have cleaner code and you will spend less time looking for bugs down the road, as time passes by.

6. Better management of memory: Memory leaks can occur in object-oriented programming, and apps and they are known to decrease the available memory for an app to run causing the app to fail. Typically, Cocoa Touch APIs used to support Automatic Reference Counting(ARC). This is a streamlined way to handle memory management. But when looked upon in the context of the core graphics API, ARC is not available, it is up to the developer. This is a common pitfall when an app is using big data buffers, video or graphics. When the amount of memory used is just too much during a memory leak, the app becomes shut down by the operating system. In order to fix this Swift supports ARC across APIs and this stability means that programmers have to spend less time focusing on memory management.

 

The future of Objective-C

While many existing apps written in Objective-C and maintained and this means Objective-C will not become obsolete any time soon. Apple’s existing APIs require a bit of code adaptation in order to work with Swift. Xcode updates have caused this to change along with newer releases as well.

Swift vs Objective C: which is better?

There are many elements to consider to decide the best between these two dialects. Relatively, Swift is a later language while Objective C has been there since the last part of the 80s. The capacity for the language to remain comparable to the market request will be delegated awesome!

Both these dialects can make a local iOS application that is practically unclear from one another. Thus, functionality is the deciding element! It is accounted for that Swift uses 60% lesser code than Objective C. As true C has been around any more time, the commonality of the language and openly accessible assets can be an essential variable as well!
 

Do I have to know Objective C to learn Swift?

This is perhaps the most legend around these two dialects. It is vital to comprehend that Swift isn’t the “replacement” of Objective C. Swift is created by Apple to make the creating system more straightforward, quicker, and more exact.

To learn Swift, you don’t require earlier information on Objective C. Indeed, Swift is simpler and requires no earlier coding information to learn it.
 

Is Swift quicker than Objective C?

Apple expresses that Swift is practically 2.6 times quicker than Objective C. The speed at which one can code utilizing Swift is essentially higher than on Objective C. The syntax on Swift is a lot less difficult and direct. One can focus more on the core center piece of the code rather than zeroing in on the standards whereupon the code must be composed.

Swift additionally performs better. The language is generally more youthful; henceforth the stage is viable with numerous other existing advances.

Swift is additionally an open-source language. This is fundamentally a bypass for programming dialects in the setting that engineers can continue refreshing the language over the long haul, making it stay important on the lookout.

 

Conclusion on Swift vs Objective C 2022:

There is no doubt that Swift is the future for iOS apps development. It is time Objective-C took a back seat and enjoyed the show put up by its successors.
