Xcode breakpoints greyed out and not working

You should also be able to right click directly on the break point and choose "Enable Break Point" from the pop up menu.

OK...

You have all your breakpoints generally disabled. This will gray out and ignore breakpoints even if they individually say they are enabled.

Go to the Debug menu in Xcode and select Activate Breakpoints.

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

Open your Debug Area:

Enable the Breakpoint and make it highlighted. BOOM!
