Absolutely agree with the last point. While I wouldn't expect a designer to throw down much Objective-C quickly, the "move this element 5 points to the right" game can be played by a designer.
Add 5 minutes of guidance from a developer and some forethought (subclasses for common button idioms in your app and how to apply them to elements; storyboard overview; a hand from a developer to hook up a table view cell nib, etc) could save the developers a lot of time. Even gawds, understanding the naming conventions around assets.
