Development Environment: Xcode 15.4, macOS 14.5 Run-time Configuration: macOS 14.5 (not iOS) Description of Problem: I want to add a QuickType bar for password autofill to provide a password by tapping a suggestion from the QuickType bar. I need to get prepareInterfaceForExtensionConfiguration called in the Autofill extension when enabling the following path: Settings -> Privacy & Security -> Extensions -> Password Auto Fill -> Select App Extension. I have followed the documentation: prepareInterfaceForExtensionConfiguration() Set the Property List Key ShowsConfigurationUI to YES. Implemented override func prepareInterfaceForExtensionConfiguration() {} However, the method prepareInterfaceForExtensionConfiguration is not being called as expected.
