ios - unexpectedly found nil while unwrapping an Optional value uint32 swift -


when try set results label string containing uint32 app crashes , error message "unexpectedly found nil while unwrapping optional value".

i figured meant have add ! variable when try issue "operand should have optional type, has type uint32.

var fingers = arc4random_uniform(6)  result.text = "incorrect, holding \(fingers) fingers"

this surely work:

var result: uilabel = uilabel() var fingers: uint32 = arc4random_uniform(6)  result.text = "incorrect, holding \(fingers) fingers"  println("\(result.text)")
