Debugger not working

My code is crashing and I wanted to trouble shoot and turned on the breakpoints and nothing happened (it did not stop at the break points). I opened up Edit Schemes and selected the Run selection on the left. I noticed it was set to Release and set that back to debug. Then under the debugger pulldown the only selection was GDB so I selected that.

But now when I try to run the program I it just stalls saying and in the information window it has a progress bar and it says "Attaching to Money List" and that is it. I went out to dinner for an hour and came back and it is saying the same thing?

I have never seen this?

 

I reinstalled it and it is working again. Don't know what I did.
