Future of Swift for iOS App Development

A brief history of Swift

A team began to work on Swift in 2010 before Apple publicly launched it in 2014 at the Worldwide Developers Conference.

Several startups and indie developers started experimenting with the features of this language, including brief syntax and reduced crashes. Swift had been created to be a clear and short language that was powerful and simple to understand. Nevertheless, to many individuals, it appears to be an evolution of Objective-C.

• The initial version of Swift had been 1.0, which was upgraded to Swift 2 in 2015.

• On 3rd December 2015, an updated version, namely Swift 2.2, become available as an open-source application for Linux and Apple’s platforms.

• The 3rd version, namely Swift 3.0, likewise underwent a significant evolution where there was a modification in its syntax.

• Afterward, Swift went through lots of changes in the 4.0 version where it is possible to update the code written with earlier versions by making use of migration functionality.

In a nutshell, it can be rightly asserted that Swift has turned out to be a powerful and extremely popular iOS programming language at present. In case you have any doubt, we have mentioned the main features of Swift to convince you that it is the future for iOS app development.

Top 6 Features of Swift

1. Open-Source
Swift.org, which performed the Swift application development, is a site dedicated to the Swift community. It has been created with a bug tracker, source code, normal development lists, and mailing lists.

A Linux version is likewise provided by Swift.org and a Linux toolset consisting of the LLDB debugger, package manager support, and the REPL. Using Swift, you will hire iOS app developers and create applications for iOS, tvOS, OS X, and watchOS. However, it runs only on a Mac.

Put simply; Swift helps to make the process of developing applications faster and safer.

2. Advancement in syntax
It will be feasible to write more expressive code using the innovative syntax features of Swift. In addition, innovative features of Objective-C, like generics explanations, have been used by the SDKs, which help to make code cleaner and safer.

3. Interactive playgrounds
Playgrounds of Swift are extremely beneficial for professional programmers. It enables them to test out new algorithm routines or graphics without building an entire iPhone application.

Apple has likewise added inline code execution to playgrounds that assist the developers in writing an algorithm or creating lots of codes while receiving feedback. Again, this will help to enhance the speed of writing the codes to a great extent.

4. Safety
Swift helps to remove entire concept code groups. For example, variables will be initialized before usage, integers will be verified for overflow, and memory will be handled automatically.

One more positive aspect regarding Swift is that it is impossible for the Swift objects to be zero, implying that a compiler error can be produced once you write a bad code. Put simply, it will be feasible to fix any problem while the code is written, and this will minimize the money and time that you will be spending on fixing glitches.

5. Powerful and fast
There has been a significant improvement of Swift by dropping legacy C conventions. Instead, it uses an extremely powerful LLVM compiler to convert Swift code into highly optimized native code.

Object categorization has become considerably faster, unlike Python with the help of Swift. It offers essential object-oriented features to the programmers, such as protocols, generics, and classes.

6. Objective-C Interoperability
The complete compatibility of Swift with Objective-C enables you to create a project that consists of files created in any of the two languages. Thus, it is possible to build up applications having a mixed-language codebase. Moreover, elements of the functionality of your app can be implemented by making use of the most recent features of Swift, and you can add it easily into the current Objective-C codebase.
