I could override printDocument, but I’m not sure how to get the printSettings that I need to pass through to printDocumentWithSettings. Looking at Apple's documentation, I think I can get these by calling dictionary() on an NSPrintInfo object. That returns an NSMutableDictionary, but the compiler won’t let me use this as a printSettings argument: "Cannot convert value of type 'NSMutableDictionary' to expected argument type '[String : AnyObject]’" Do I need to iterate through the NSMutableDictionary and create a Swift Dictionary from it? Maybe I’ve missed an easier way of doing this. All I want to happen is to be notified when the print operation is completed.
