Xcode 6.4 Scheme Option Disappeared in El Capitan Beta

Question

After I upgraded my Mac from Yosemite to El Capitan developer beta, the scheme option button in Xcode 6.4 is disappeared from the tool bar:

But Xcode 7 beta works fine

Is this an El Capitan bug? Is there any solution to fix this apart from rolling back to Yosemite? Thank

Answer 1

You don't need that button; the same options are available from the Product menu. So even though it's a bug, you can work around it for now, easily enough.

Answer 2

It is a UI bug and will probably be fixed soon. I've been working around the issue by dragging the Xcode window so that it is very wide (wider than my monitor). After a certain width, the scheme selector comes back into view.

Answer 3

Make xCode fullscreen. It works properly only in fullscreen mode.
