iSwift

iSwift is the easiest way to convert your Objective-C code to Swift.

Features

• Ultra fast: Automatic as-you-type conversion, so that you don't lose even a single second. Yep, instantly.
• Drag-and-drop: Drop your Objective-C source onto the app icon, import the file and have it instantly converted. Yep, just like that.
• Smart: Syntax highlighting, autocompletion, live syntax checking and error reporting, and lots of advanced editing options. (Powered by Peppermint)
• Friendly UI: A neat editor, your sources side-by-side and all that packed in a beautiful easy-to-use User interface. What more can you need?
• Sophisticated: iSwift tries to recognize, parse and convert all Objective-C code (2.0 too!) to valid Swift code.
