Objective-c – Error: This class is not key value coding-compliant for the key keyPath

iphoneobjective-cxcode

 UIStoryboard*  sb = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    UIViewController* vc = [sb instantiateViewControllerWithIdentifier:@"SettingsViewController"];
    [[self navigationController] pushViewController:vc animated:YES];

Trying to push a viewcontroller from my NavigationController in Storyboard and I keep getting this error.

* Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<SettingsViewController 0x1f98f100> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key keyPath.'

libc++abi.dylib: terminate called throwing an exception

Best Solution

I got this error becouse I had put something in the "User Defined Runtime Attributes" field in the "Identity inspector" tab. By mystake I left the default keyPath value for the Key Path column and that caused the problem.
