title: NSUnknownKeyException error with UILabel swift
body: <p>I keep getting this error with regards to a UILabel I have setup in a new class. <code>'NSUnknownKeyException', reason: '[&lt;UIViewController 0x7ff9c255d120&gt; setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key winnerLabel.'</code> (winnerLabel is the name of the UILabel). I have ensured that the class the ViewController's class is correct (in Main.storyboard>Select controller>Utility Area>Identity Inspector>Class). From asking around I have been told that 'The outlet name that's in the xib is out of sync with the name in the class,' if this is the case then how would I go about updating the the outlet's name in the xib/ storyboard. Any help would be greatly appreciated. </p>
  
  <p>Edit: My question has been marked as a duplicate of another question. I have already explained that my problem was not solved by the answer to that question (^^^"I have ensured that the class the ViewController's class is correct (in Main.storyboard>Select controller>Utility Area>Identity Inspector>Class).</p>
