Hi,
I'm having difficulties figuring out how I can reliably detect if the macOS system PHPhotoLibrary is available.
If I place the system Photo Library on an external drive and then eject it, other apps on startup, such as Photos, will tell me that the library isn't available. How can I replicate this behavior?
The only API I can find for this detection on startup is "PHPhotoLibrary.shared().unavailabilityReason". However this always returns nil.
Another strange behavior is if I register a PHPhotoLibraryAvailabilityObserver class on startup when the library is available and then eject the drive, I do get a notification via photoLibraryDidBecomeUnavailable, but then directly after the call the app is terminated. This prevents the app to perform any kind of graceful termination. Is this the expected behavior? It would make sense that it's up to the developer to decide what happens if the library becomes unavailable.
Thanks
