Xcode ignores the breakpoints

Question

While working on an old objectiv-C project, in order to prepare an update for the appStore, I hit this problem: X code totally ignores my breakpoints. I can see by using NSLog() that the code is executed as expected, but it doesn't stop as it should at breakpoints.

I am using OS X Version 10.11.4 and Xcode Version 7.3.1.

I have seen a number of posts on the net about this issue, but none of the tricks proposed fixed my problem.

3 - force quit x-code .
4 - delete tha Derived Data .
