What makes Swift the best programming language for iOS developers?

When it comes to developing mobile apps, we have the convenience of choosing from a wide collection of programming languages. Swift is one such programming language that has been embraced and used by hundreds and thousands of iOS/OS X developers across the globe.

Whether you're targeting the iPhone, iPad, Mac or the Apple Watch device; Swift will offer you a brilliant flexibility of building consuming-oriented apps that are fully responsive and immersive. Continue to stay on this post as I'll be highlighting the key reasons which make Swift a de-facto programming language for an Iphone app development expert.

1. Swift comes with optimal readability

Unlike its counterpart Objective C, Swift is a lot more readable programming language. For instance, Swift can be used for unifying different keywords and eliminating multiple @ symbols that are placed in front of every object-related keyword. All the legacy conventions have been dropped off in Swift. That means, you aren't supposed to use semicolons for marking the end of different lines. Yet another interesting thing about Swift is that the method calls never nest within each other; thereby preventing the occurrence of numerous brackets. All the method and function calls within Swift utilize industry-standard list of parameters included within parentheses. Therefore, it won't be wrong to say that Swift is a clean and utmost expressive programming language accompanied by effectively simplified grammar and syntax.

2. Swift codes are faster and safer

The excellent type interface of Swift makes it type-safe. In simple words, Swift is a strong-typed programming languages that allows you to reduce the code length by a noticeable level. Since Swift's default setting is in place, any chances for false coding due to improper coding are removed as a whole. Plus, there is a memory management feature which allows you to keep a track of your coding in addition to marking red flag against a faulty piece of code. Saving you from the hassles of importing references in order to set up the main function, you can continue to code faster and with complete ease. A majority of Iphone or OSX user interface is being handled with the help of libraries; thereby playing a vital role in pacing up the iOS/OS X app development process.

3. Maintaining Swift is a hassle-free job

Unlike C which expects the developers to maintain two separate code files for improving the build time, Swift has the Xcode and LLVM compiler which can easily detect dependencies and undertake incremental builds in Swift 1.2 version. Therefore, the monotonous task of separating header file from implementation file doesn't exist any longer. Swift programming language simply combines Objective-C header i.e. .h and the implementation files i.e .m into a single code file i.e. .swift. iOS app developers using Swift can easily do away with bookeeping and spending a lot of time on creation of an impressive app logic. All the boilerplate work is being cut down and hence the quality of code and comments gets improved tremendously.

4. Interactive coding is encouraged via Swift playgrounds

Swift's all new feature called Playgrounds has worked wonders for offering an interactive coding environment to the app developers. Partially inspired by work of a former Apple employee namely Brett Victor; the Playgrounds feature allows the programmers to test all new algorithms and graphics without the need for creating a complete iPhone app. In addition to this, Apple has also added inline code execution to these Playgrounds in order to aid the programmers in creating huge chunks of code and writing algorithms while receiving the client's much awaited feedback.

5. Lesser app crashes are guaranteed with Swift Programming language

App crashing is indeed the most important concern of every app developer. Reason being that if an app crashes, the developer has to do all the coding right from scratch. It is here that the Memory Management feature of Swift comes to your rescue. It handles all the minor programming mistakes, thereby preventing app crashes to the maximum.

6. Optimum app compatibility is a default feature of Swift apps

It is interesting to know that Swift apps are fully compatible with the most recent iOS8 and OSX Yosemite. The reason for this is that the Xcode include a tiny Swift runtime library that's already embedded within app bundle, further enabling the app to utilize the latest Swift version for work efficiently on all past, present and future operating system(OS) releases.

7. Swift has fewer name collisions with multiple open source projects

As compared to the lack of formal namespace support in Objective-C programming language, Swift comes with an implicit namespace which enables the same code file to be available across numerous open source projects without the need for any names like CGPoint or NSString. Swift's infleunce with common names like Dictionary, Array and String has turned the developers more productive.


The varied benefits associated with Swift have undoubtedly encouraged iOS/OSX developers to ditch the commonly used Objective-C programming language. Here's hoping the above post would have helped you in digging deeper into Swift-making the most of this new iOS/OSX app programming language.
