My Custom keyboard extension doesn't appeared in "Settings -> General -> Keyboards -> Add new keyboard-> Third party keyboards" on simulator and real device. My keyboard extension has been working on previous versions.I tested on Xcode11 - beta2 1. File -> new -> Project... -> iOS -> Single View App 2. File -> new -> Targets... -> iOS -> Custom Keyboard Extension 3. Run on iPhone simulator iOS13 4. Go to Settings -> General -> Keyboard -> Keyboards -> Add new keyboard on Simulator. I couldn't find 3rd party keyboards. I tested same thing on xcode10 on iOS 12 simulator. It was fine and I was able to select 3rd party keyboard.It's strange that gboard and swiftkey are normally working on iOS13. Is There something that I miss new configuration or AppReview requirements?
