Swift 3.0 Empowers Apple to step in the world of Linux!

Ted Kremenek, Senior Manager, Languages, and Runtimes at Apple said,

“With the diverse ecosystem, either working on servers or applications, we want swift for everyone. Swift 3.0 is a big update since swift went on Linux platform.”

You might have read my previous article– ABCs of Swift Programming language. So now you can have the clarity about the Swift and its related programming aspects.

Swift Programming Language

Along with the features of 2.0, Swift 3.0 has come with many key features.

API Access

Swift community has drafted Swift API design guidelines for the revolution in open source process. For core frameworks like foundation, Grand central dispatch, core graphics, these guidelines were strictly adhered to achieve the optimisation. The frameworks which were developed in Objective-C will also feel the difference in Swift 3.0.

Playground support

In Xcode 8, support for the playground is featured inside. The output from the Playground can be like graphics, lists, graphs or a value over a time. A Timeline Assistant helps for the complex view which may evolve or animate. It enables you to experiment with animated SpriteKit scene as you code for it. If the code results in perfect shape in the playground, you can attach your code to your project.

Read Eval Print Loop (REPL)

It is an LLDB debugging console in Xcode. In your running app, you can take swift syntax and evaluate and interact with the app. Or you can check, how it works in script environment.

Parameter labelling

Swift 2.0 was more inspired from Objective-C but this version of a swift programming language is more into parameter labeling. Since inception, this language is changed so much, so parameter labeling had to be taken care of.


For example, new Date and Calendar types are now easy to use and faster to implement. Signatures are upfront now and constraints come after signatures.


Suppose if any unused variable or unused result is remaining in the application, a warning will be issued for it. Warnings have become more sensitive now.

Ensuring safety

Swift is now designed such that variables needs to be initialized before usage, and check for overflow for variables. Automatic memory management is there. More guidelines for syntax formations. Main safety feature from Swift is that it eliminates the nil object. A compiler will stop you from using nil object.

With Swift 3.0, Apple has stepped in the world of Linux. Now developers are waiting for its Android presence and if Apple succeeds in that, then nobody will stop Swift programming language from winning the race.
