Hi all.
This looks like a compiler bug of some kind, which has halted my progress. I'm trying to instantiate a view controller from a storyboard, using syntax that Xcode's auto-completion suggested and that is perfectly valid. But it is complaining that it has an extra argument. I've deleted the build-products directory, rebooted, checked the file for invisible characters... WTH?
Anybody see this kind of thing before? Note the double-flagging, including a line that doesn't even have instructions on it.
