Important: if you don't see the “Xcode Source Editor” menu item under System Preferences -> Extensions, this is most likely due to a corrupt installation of the Xcode itself.
If this happens, reinstall both Xcode and Swiftify from the AppStore.

Swiftify Xcode Extension allows converting your Objective-C code to Swift 4.2 or 4.1 right in Xcode.
The app includes Xcode & Finder extensions and the Advanced Project Converter app best suited for gradual project migration.

To install Swiftify for Xcode in Xcode 10 (or Xcode 9) on macOS Mojave (or High Sierra):
• Quit Xcode;
• Launch “Swiftify for Xcode” from your Applications folder and follow the link to get your API key (if you leave it blank, the output will be limited to 1 KB);
• Enable Swiftify extension in System Preferences -> Extensions -> Xcode Source Editor;
• Restart Xcode;
• Use Editor -> Swiftify menu to convert selection, whole file or clipboard contents from Objective-C to Swift.

The converted code is transferred over an encrypted HTTPS connection and is NEVER stored on our servers!

Great tool, but over priced

There is no mention of cost until you actually go to run the tool. It costs $99 a month yes A MONTH for anything useful. Save yourself some time and just move on to somethign else.

Thanks for your valuable feedback!

The included Xcode extension can be used for free, and should be still useful for occasional usage. The Advanced Project Converter (which requires a paid plan) is our own Xcode-like IDE that covers some essential functionality missing in the Xcode itself.

We will improve the UI to make all of this more clear to our users!
