Xcode debugger sometimes doesn't display variable values?

Question

This happens to me pretty often. For example, right now I have the debugger stopped at a breakpoint in a method . . . and it isn\'t displaying any variable values at all.

Answer 1

A possible solution is to set the Optimization Level for your current target Debug scheme to none.

Project -> Target -> Build settings -> Optimization level -> Debug (or whatever fits your project) -> None
