NSOperation has a property with `-finished:` as the setter and `-isFinished` as the getter.  It’s not uncommon for method names used by an operation’s author to collide with these, depending on exactly how the importing is importing those methods, how the overlays are set up, and so on.

IMO the best way to fix your specific issue is to adopt Swift 3 naming for your methods:

    final func finish(receivedErrors: [Error])    
    final func finish(receivedError: Error?)

which lifts you out of the ‘finish’ space entirely.
