Every mobile app developer should really take a look into Swift if they haven't already. It is quickly ramping up, not only as a supplement to Objective-C for the Mac, iPhone, iPad, Watch and the like, but it will be replacing C for embedded-programming on all Apple platforms. It was designed to make programming for Apple safer and easier than it was with Objective-C. Due to multiple main features, Swift is in the running for the go-to programming language used to create immersive consumer-facing apps.
Easier to read and maintain.
Most importantly, Swift is safer.
While Swift is faster, requires less code and allows for memory safety in iOS programming, it's unlikely that apps written in Swift for Apple will complement any other systems that use more than a generic code. It probably won't be able to extend software freedom beyond Apple's restricted range of information.
