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!
If you are interested in the offline version with a similar functionality, it's also available at https://objectivec2swift.com/#/offline-converter/

Added support for Swift 5.
Now you can switch between the Swift 5 and Swift 4.2 outputs in the Preferences dialog.
Ratings and Reviews
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 :)
I have to echo the other feedback here. This tool does exactly what it says: converts Obj-C to Swift.
For me, it took a medium-sized project I was considering keeping in Obj-C for timing reasons and made porting it to Swift realistic.
It might not match your exact naming style on an "if let" or other preferences you might have, but it gets the bulk of everything correct — especially functionally — and saves a *ton* of time. And honestly, once you know that you've saved so much time, the clean up is kind of fun.

Thanks for your awesome feedback!
We have just completely refined naming of conditional unwrapping (`if let`) variables, to use shadow variables as suggested by Ray Wenderlich style guide.
Stay tuned for further updates!
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!
