Swiftify

When Apple rolled out Swift back in 2014, Objective-C was set to be replaced. Even nowadays, however, there are plenty of apps and projects that still use Objective-C, and developers are faced with the prospect of either starting again from scratch or attempting to convert them to Swift.

Swiftify for Xcode is designed to automate much of the conversion process, handling the task of replacing syntax while letting you focus on other aspects of migrating your project to Swift.

As the name suggests, the service can be accessed directly from Xcode. You can access it from the Editor menu, where you have the option of converting a selection of code or a whole file. You can also copy Objective-C code and paste it as Swift.

It's also possible to convert files directly from Finder without booting up Xcode. Simply select one or more files and start the conversion from the context menu.

Finally, the Advanced Project Converter app is designed to help you manage an entire project. It lets you explore it from a dedicated UI and select files to be converted. Processed items are automatically added to the project file. The app is included in Swiftify for Xcode, but it can only be used with a Cloud subscription or Swiftify Pay As You Go credits.
