How do I toggle between Debug and Release builds in Xcode 6 / 7 / 8?

Question

How do I get Xcode to build an OS X app in release mode? I can only seem to find instructions for earlier versions and none of the screenshots match. I didn't see anything when I put "release" into the help menu's search.

In Xcode 6 - 10:

Choose Product -> Scheme -> Edit Scheme. Change the Build Configuration under the Info tab.

Shortcut: hold Alt⌥ and click the run button ▶.
