What is an SWIFT file?
A SWIFT file is a source code file written in Swift, a programming language introduced by Apple with iOS 8 and OS X Yosemite. It is designed for writing and compiling apps and can be used with Xcode beginning with Xcode 6.
Swift uses a style familiar to iOS and OS X Objective-C developers, but makes programming easier and more like programming in a scripting language. Swift offers features such as automatic memory management and integration with existing Cocoa frameworks.
