Thanks Brent!

This solved my different but related issue on iOS:

Taking the standard template for a Master-Detail Application with Core Data and making all the changes so that it compiles, leads to NSFetchedResultsControllerDelegate’s controller(_:didChange:at:for:newIndexPath:) function not being called.
Adding @objc(controller:didChangeObject:atIndexPath:forChangeType:newIndexPath:) makes it get called. Fantastic!

Running the app gives me errors such as "Must implement numberOfRowsInTableView: and tableView:objectValueForTableColumn:row:” when the swiftified version "numberOfRows(in tableView: NSTableView) -> Int” and the required methods to support a view based table exist -- unless I got them wrong.
