In my application, the user is allowed to edit his contact using native contact screen (ABPersonViewController). But since iOS 9 I have noticed that the avatar edition doesn't work anymore : everytime I try to take a photo for the contact, the camera screen is black and I can only cancel. I have made a test project to test if this happened with the new contact screen (CNContactViewController), and I have the same issue too.
I have also noticed that the first time I try to go to this screen, even if I accept the popup asking me for access to the camera, this setting is not saved (if I got to settings > privacy > camera on my iPhone, I don't see my app in it). But if I take a picture from another part of my app (which allows image sending), the setting is written correctly (but this doesn't solve the contact avatar edition issue).
Anyone noticed that too ? I've tested on a random application from the app store too (Simpler) and they have the same issue.
