To install Swiftify for Xcode in Xcode 14 (or Xcode 13) on macOS Monterey (or Big Sur):
• Quit Xcode
• Launch “Swiftify for Xcode” from your Applications folder and follow the link to get your API key
• 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

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.
Email contact@swiftify.com if the issue persists.

Gets you about 90% there.

This tool is a godsend. Apple should buy it and roll it into Xcode. It doesn’t get everything right, but it’ll still save you hours or days. A small app can be converted to Swift in a day or two. A medium-sized app in less than a week. Much better than starting from scratch because you can compare your files side-by-side after converting your project with the subscription-level purchase. Many thanks to Alex for providing this!

Great tool still in 2021!

I'm finally getting around to converting one of our large apps and I can't imagine doing it without this tool. It's incredibly well priced and will get most of the boilerplate stuff done for you, although it does still take a fair amount of work to convert everything. One tip is to annotate nullability and generics before you convert the file so the tool can use those as a guideline. Honestly, this tool saved me so many hours it has paid for itself 100x over.

Excellent Starting Point

I recently had to convert a project from Objective-C (which I do not know) to Swift and found Swiftify to be an excellent way to start that process.

In addition to a time-saver, over the course of using Swiftify for a few weeks I've learned quite a bit about Objective-C. I now feel much more comfortable taking the starting point in the conversion process that Swiftify provides and doing the last bit of conversion to Swift myself faster & more accurately. Highly recommended!

Thanks for sharing a really interesting user story!
Sounds amazing that Swiftify even helped you to learn Objective-C.
It's also great to hear that you have successfully used the converter even without prior knowledge of Objective-C!
Wish you all the best with your projects :)
