What's the difference between "Build and Go (Run)" and "Build and Run" in XCode?

Question

What's the difference between "Build and Go (Run)" and "Build and Run" in XCode? Why is this so Ambiguous?

Answer 1

Build and Run will always Run. Build and Go will load the debugger, if relevant.

Answer 2

If you just click "Build and Go" it's the same as "Build and Run"... any modified files are compiled and linked then your application is executed.

But if you click-and-hold on the "Build and Go" icon then after a second or so you should see a pop-up appear that presenets the choices "Build and Run", "Build and Debug", "Run Executable" or "Debug Executable". (Not the best use of UI IMO :) )
