You don't have to downgrade for this.

Perform the following things and it should work: - Clean your derived data (Xcode -> Preferences -> Locations -> Click on the small arrow next to Derived data). Make sure you read about derived data before performing this. If you have a complicated project and have made some silly mistakes (ex: deleted some file) you may have to figure out the issue before re running your app. But it won't be that difficult. - Delete your app form your device/simulator - Remove your Facebook app approval from Facebook (Setting -> App - > Click on the "x" to delete your app)

Rerun the app and everything should work.

Good Luck!
