Swift : The Make Over for iOS App Development
Since Apple opened up iOS SDK to developers way back in 2008, Objective C has been heart and soul of any iOS app. But now with the launch of Swift, game is going to be changed.
To understand how Swift will impact future of iOS apps we need to know 3 things:
1. Why Swift (a new programing) language has been required?
2. Benefits of Swift over Objective C.
3. Developer community acceptance of Swift.
I will start with my first question, which is Why A new language… “Swift”.
My response to this is very simple, “A smartphone programming language has to be equally smart”. While Objective C do all the jobs of app development, it’s not smooth and sometimes its very hard to compile multi level libraries. With the launch on iOS 9, Apple vision to give more power to developers came to light. However App approvals and listings will be hold by Apple, but with swift, iOS development can be done from any OS/Platforms. It will give power to developers to create their own tools for an iOS app development. I like the way we code in Swift. It’s no more like writing a machine language. It closely resembles with our everyday language. Its an modern programming language with advanced error handling modules and a lot of syntax improvements. The one thing I like most is that you can still use your Objective C commands, thanks to interoperability. Moreover it’s going to be an Open Source.. 🙂
In above we have noticed key differences between Objective C and Swift but “there is much more”.
First thing I would like to quote here is that whatever language you use framework for an iOS app development is going to be same. For iOS app development its important to have knowledge of frameworks which produces same APIs either to use in swift or objective C. Swift has to offer a lot on top of Objective C, but always keep in mind that you can use Objective C codes inside swift as well.
For me the best features of swift are Dynamic Library Support, unified memory management, real time debugging and faster processing. Icing in cake is easy to understand code and low learning curve.
First thing I would like to quote here is that whatever language you use, the frameworks/libraries for iOS app development are going to be same. Apple already provides with same APIs to the existing frameworks in both Objective C and Swift.
Developer Community Acceptance of Swift: More than 16K repositories on github itself defines the story.
Developers will love simpler way to code and swift is designed for that. Swift Playground is boon for developers to test a part of their code without compiling whole code instantly. I believe Swift will be used for most of the new applications from 2016 and by that time the community support and developer engagement will be too high for swift. Its already been voted as most loved language. And the most loved word among developer community, it will be an open source.
After having all three points illustrated in above paragraph, now its time to conclude that how swift will impact iOS app development. The apps developed using swift can be crash proof, more secure, low on device memory and faster on processing. These are the features which will improve gaming and enterprise app space a lot.
