These two errors keep popping up and i can't seem to figure what the problem is. Im making an app and wanted to have scenes so I followed the tutorial and then copy and pasted my code into what was in the tutorial and these errors popped up.

let smileyScene = SmileyScene(fileNamed: "SmileyScene")     
self.view?.presentScene(SmileyScene, transition: doors)

Cannot find an initializer for type 'SmileyScene' that accepts an argument list of type '(fileNamed: String)'
Could not find an overload for 'init' that accepts the supplied arguments
