问题
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
回答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.

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.

Make xCode fullscreen. It works properly only in fullscreen mode.
UPDATED Method valid only for MBP 15 inch (retina)

Confirm that you are not using any variant of xcode 6. I also got the same issue with xcode 6.4, but when I used xcode 7, everything was working fine.
So get xcode 7. It will work
Here is a snippet of bug with OS X El Capitan Developer Beta 7 Release Notes

that was a UI bug and just expand your Xcode window, than you can see that option will appears in Xcode.
