Xcode breakpoints greyed out and not working

Question

I'm debugging an Objective-C app on the iPhone simulator. The app compiles and works. Xcode settings previously let me set debugger breakpoints and have the debugger actually break.

Now, the breakpoints show up in grey and the debugger doesn't stop on any breakpoint. Clicking on the breakpoint makes it light grey, but not blue like normal.

Can someone tell me which setting I need to revert to enable debugging again? Thanks.

Answer 1

Open your Debug Area:

Enable the Breakpoint and make it highlighted. BOOM!

Answer 2

In the top menu, open Debug and click Activate breakpoints. You can also use the keyboard shortcut: Command ⌘ + Y.
