Things To Consider Before Choosing Swift For App Development

Since its announcement in 2014 by Apple, Swift has grown to become quite a popular programming language for iOS app development. Swift is fast, safe and an expressive programming language. It has the ability to improve runtime performance through the ways of low-level optimizations. Swift seems to be very attractive due to its features still you need to consider a few things before choosing it for app development.

Swift Binary Size

Do you want your application to be binary size so that it becomes easy to be downloaded and installed by people? Then in that case you need to know the additional components which are embedded in it and how the bundle is structured. Compared to Objective-C, the application build on Swift is bigger as XCode embeds a swift runtime library in the application bundle. Until the time it stabilizes the ABI, Swift will keep on evolving. Apple keeps on embedding runtime libraries in the app to make sure the Swift version remains consistent throughout the versions of different OS releases.

ABI stability

The ABI stability feature in Swift has been deferred to the Swift 4.x release which is expected to take place at the end of this year. So before we get any further, lets understand how it is going to affect development.

By making use of ABI stability, developers will be able to get the pre-built libraries compiled using a random compiler linked. Using the ABI stability, it is possible to interact and interface with the codes compiled in different versions of Swift. This means the developer will not have to worry about the compiler version when compiling the code. In the absence of ABI stability the binary libraries will break in the future version of compilers. The need to embed Swift runtime libraries and framework within the application bundle will be removed with ABI stability.

Today more number of iOS apps are developed on Swift programming language. There are a number of reasons to do it and to know more about the same click here. So if you are planning to opt for Swift for iOS app development, make sure you keep these things in mind.
