i had same problem xcode8/ios10. problem due call save core data context inside following method.
- (void)controllerdidchangecontent:(nsfetchedresultscontroller *)controller { [self methodcallingsavecontext]; } the
methodcallingsavecontext calls save core data context. in order break recursive call rewrote method in following way:
- (void)controllerdidchangecontent:(nsfetchedresultscontroller *)controller { dispatch_async(dispatch_get_main_queue(), ^{ [self methodcallingsavecontext]; }); } now working again.
