Detox 14.0.0 drops support for iOS 9.x simulators, and thus it also drops support for any API that is deprecated in iOS 10 and above. This includes legacy remote and local notifications handling API. These APIs have been deprecated since iOS 10, and we believe we've given app developers enough time to use the modern APIs. Make sure you transition to the UserNotifications framework as soon as possible.
Please note that for React Native apps, PushNotificationIOS (RCTPushNotificationManager) is severely outdated and does not support these modern APIs. It is recommended to transition to a more modern solution. While it is sad that such an important app feature is let to stagnate so much by Facebook, it cannot be the concern of Detox. It is up to RN users to keep their apps up to date with the latest Apple APIs.
Our own React Native notifications solution supports these modern APIs.
