Developers will find that they write less code in Swift, and modern language features support them in keeping lines of code more readable. Swift will keep the entire Apple ecosystem at the forefront of programming as it continues to evolve, thanks to dynamic library support in iOS and Swift. Open source projects, third-party SDKs, and frameworks that integrate with home automation, devices, and social services will be easier to integrate without increasing build times. Swift is almost as fast as C++ in some algorithms and the latest release of Xcode 6.3 and Swift 1.2 point to additional performance optimizations on the horizon.
