Navigate Between Projects in Xcode 7

Question

What keyboard shortcut can be used to navigate between open projects in Xcode 7?

Have seen these suggestions ([1], [2], [3]) for prior releases of Xcode, none seem to work in v7:

Cmd + `

Cmd + Shift + `

Cmd + Ctrl + ↑/↓.

Answer 1

System Preferences->Keyboard->Shortcuts->Keyboard->√ Move focus to next window.

then, use Cmd + `

Answer 2

Per the comments the answer here is to use Cmd + ` when Xcode is not maximized, otherwise you can use 3 finger drag.
