On June 2, 2014, Apple announced a switch to Swift as the programming language for their operating systems. We need to start paying attention to this shift, because Apple is slowly fading out the previous language, making a switch to Swift a necessity.
Swift replaces the previous language used by Apple, Objective C. Swift provides more secure programming patterns, adds modern features for easier programming and is more flexible. Just as important, Swift is more fun.
Apple has been developing this programming language for many years before it reached us – the developers of the Xcode environment - about two years ago.
Languages do not die easily. Objective C still exists in many parts of Apple’s code and will always be there. However, applications and developments that are dependent on past technologies become difficult to maintain and will finally die. So should we move on to other languages? And if so, when?
The company has brought many changes in the past few years. It is a good idea to progress with Apple; their changes bring support for new resolutions in new devices, better performance, tools to deal with graphic challenges, as well as interfaces that were originally complicated and are now becoming easier to implement. Therefore, we should heed the changes the company brings to the development environment.
In some cases, previous functionality is outdated and Apple or any other third party provide newer and faster methods/algorithms that can be used by developers.
There is no easy or magic way to move quickly to Swift.The change will require the investment of a great deal of thought. You will be adopting safer programming patterns and possibly even a new design, as the only way to upgrade may be to rewrite your application.Yes, it’s time to move to Swift. And today, it’s a really good time, as Swift Ver. 3.0 is considered stable and safe to implement.Another important reason to make the change, in my opinion, is programmers. Colleges in Israel and abroad have been teaching Swift in the past two years. New Objective C developers have not entered the workforce.A graph illustrating developers' love for Swift (stack overflow):
So where should you begin? There are a lot of great ways to implement and rewrite code. However, when approaching this task, make sure to plan the code correctly and in a considered manner, because Swift is here to stay for many years.
