Terminating app due to -[GLKViewController loadView] loaded the "2-view-3" nib but didn't get a GLKView.'

Question

1. i am using OpenGL framework in first time.Nothing i have written in code.
2. #import

@interface ViewController : GLKViewController

@end

Answer 1

Delete the view from storyboard and add GLKView instead. It should resolve the problem.

Answer 2

It looks like the xib that has been loaded doesn't contain a GLKView. Make sure you add a UIVIew and change the type to GLKView in the inspector panel on the right hand side of xCode.
