libc++abi.dylib: terminating with uncaught exception of type NSException

·1 min

I ran into this error today in Xcode while learning iOS app development. I had wired up the objects in the Interface Builder and then changed the name of one of the outlets in my code.

To identify the issue, go to Main.storyboard, and right-click on View Controller at the top of the phone outline and remove any outlets with yellow flags.
