Do you have Objective-C source code you need to convert to Swift 4.1 or 4.2? Swiftify can pull this off with a simple single click.

Install the Swiftify for Xcode extension from the Mac App Store to see a new Swiftify submenu in Xcode’s Editor menu. To ensure it’s enabled, visit System Preferences > Extensions and tick Xcode Source Editor under Swiftify for Xcode.

Here you’ll find three options: Convert Selection to Swift, Convert File to Swift, Paste as Swift. And the names pretty much say it all when it comes to their functionality.

Swiftify also has a Finder extension that you access by Control-clicking on a folder, ZIP file or project/source file, then selecting a conversion type from the contextual menu.

Introduced after the initial public release of Swift, Swiftify’s converter has come a long way. It now handles complex conversion issues, with full block and closure support, class hierarchy support and a deep understanding of data types and many complex Objective-C constructs.

If you’ve got an Objective-C code base, Swiftify is a must-have for your toolkit. And even if you already work exclusively in Swift, Swiftify is still handy for converting the Objective-C sample code you come across online.
