[SOLVED] __CRASHING_DUE_TO_PRIVACY_VIOLATION_

__CRASHING_DUE_TO_PRIVACY_VIOLATION__

In Crashlytics, I can see iOS 10 users are getting this crash frequently. However, when I test in Simulator using iPhone 7/10.2, I'm unable to reproduce the crash. In my plist, I already have strings for

NSCalendarsUsageDescription, NSMicrophoneUsageDescription, and NSPhotoLibraryUsageDescription.

Here is the stacktrace from Crashlytics:

Any clue how to reproduce or fix this? I do allow user to access contacts, but I am not prompted for any permission when I test that feature in simulator. However, when the user accesses the camera from my app, the simulator does prompt me for a permission. That makes me think that a string is not needed for accessing contacts.

Solution

I had to add a string for NSCameraUsageDescription in the plist because user is allowed to take photos.
