It seems to have nothing to do with my code. I can only guess maybe it is caused by SFSafariViewController since it is xpc?

Comments

We have this exact same crash. It's also the top crash for us. However, the app was built using XCode 6 before iOS9 came out and doesn't use SFSafariViewController so that's probably not the cause
