cannot decode object of class (AMPathPopUpButton)'

Question

I'm new to Swift and I'm using xCode 6 Beta 5. My issue is I'm getting compiler error:

"Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '* -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (AMPathPopUpButton)'"

when adding AMPathPopUpButton to my application UI. Any one can help??
