The source editor extension supports `APLConfiguration` subclasses written in both Objective-C and Swift.

* In Xcode, open your `APLConfiguration` subclass .m or .swift source file.
* Tap Editor ‣ Appfigurate SE ‣ Encrypt strings.
* All instances of `ENCRYPTED_STRING` will be updated automatically with the generated ciphertext.

If the source editor extension could not parse your .m or .swift source file, an error message will be displayed at the top of the Xcode source editor window. Follow these [Troubleshooting](/appfigurate-se-user-guide/xcode-source-editor-extension/troubleshooting.md) tips.
