Thanks so much! For accessing the NSCameraUsageDescription key, we need to verify and request authorization as suggested in documentation. Was it compulsory or not? Because one of my app review messages said, "1. The app crashed the first time after tapping 'Allow' in the camera permission request. The app then kept crashing upon relaunch." Here's the documentation https://developer.apple.com/documentation/avfoundation/capture_setup/requesting_authorization_to_capture_and_save_media
