Try placing the translations in the InfoPlist.strings file, your image links are dead so I can’t check them.

Does it work if you use Xcode 13?

Turns out Xcode 14 removes the entitlement from the xcent file before embedding that in the code signature. You should be able to do something like: /usr/libexec/PlistBuddy -c "Add :aps-environment string development" "$TARGET_TEMP_DIR/$FULL_PRODUCT_NAME.xcent" In a build script towards the end of the build.

@MarkT I configured a new project in Xcode 16.2RC and the BUILD_DIR environment variable doesn't vary between a normal build and a preview build anymore.
