  • You should post the Swift code that actually caused the error, not the compiled code. Also stack traces help too. – Alexander Jun 22 '16 at 23:09

It means that there there are instructions that lead to a crash, such as force unwrapping something that doesn't exist, and getting a value of nil.

Take a look through your code and see if there are any situations where you force unwrap something that does not necessarily exist.
