iSwift Objective-C to Swift converter. As you type. iSwift is the easiest way to convert your Objective-C code to Swift. Apple has developed the Swift programming language to provide a more intuitive resource for building both macOS and iOS application. Swift is intended to be more concise and easier to learn, so there is no doubt that, in time, it will completely replace Objective-C, even though at the moment both languages are supported.
