That’s it! Thank you, Quincey!

It no longer crashes if I put a question mark after replacementString:String and then ignore XCode’s warning, but I went ahead and implemented the “shouldChangeTextInRanges" method instead. Thanks for the quick, correct response!

Is this a disaster in Swift-to-ObjC bridging, or have I done something wrong to cause it?

  func textView( tv:NSTextView, shouldChangeTextInRange range:NSRange, replacementString:String ) -> Bool

The problem is that the replacement string can be nil (if only attributes are being changed, which is what happens when you Command-B), but the bridged signature is missing a ‘?’ on the replacementString type. (You can see this if you change the type to ’String!’, ignore the warning, and see the log message when you run.) Why this is, I don’t know, but I doubt it’s your fault.

This delegate method is described as “superseded” in the header file. I suggest you try using the recommended method:

   func textView(textView: NSTextView, shouldChangeTextInRanges affectedRanges: [AnyObject], replacementStrings: [AnyObject]?) -> Bool
