XCode 7: Launch screens may not set custom classnames

I created a simple application using Xcode 7 Beta 2. The application simply contains class MyAppDelegate, MyViewController, MyMain.storyBoard

and has "Is Initial View Controller" checked:

You can only do one or the other. Somehow I had "Is Initial View Controller" still checked by mistake, and it took me a while to hunt that down!
