Answer 1

Generally, this kind of error occurs due to duplicate classes and xibs in your project folder. For example, in my project I had some class files duplicated(.h/.m files). You can see these duplicate classes under target->Build phases->compile sources.

Just look and remove extra classes. Problem will be solved.
