Stepping into NSMakeRange every time I push the step over button where the debugging line has a call to NSMakeRange

Question

When I am debugging my app it steps into NSMakeRange every time I push the step over button where the debugging line has a call to NSMakeRange. Why do I get this error?

Answer 1

This happens because NSMakeRange is an inline function, which means it isn't a real function, the compiler copies its code wherever you use it (a bit like a macro), so its code is actually part of your code.
