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

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 .

The easiest way with a project that has the default set up for schemes is just to do Product -> Build For -> Profiling.


When you want to generate a release build, choose Product -> Archive. That is a Release build. Now you can export as a Mac OS X app.
