I am trying to implement BWWalkthrough in my project. However I get an error stating
Unknown class _TtC20BWWalkthroughExample27BWWalkthroughViewController in Interface Builder file.
Could not cast value of type 'UIViewController' (0x195bca580) to 'AppName.BWWalkthroughViewController' (0x10042c3a0).
let walkthrough = stb.instantiateViewControllerWithIdentifier("walk") as! BWWalkthroughViewController
Your storyboard doesn't seem to be linked to a
BWWalktroughViewController. Find where the view controller should be a
BWWalktroughViewController, and check if it is one.
