Disable -optimize-debug for Clang
It results in Xcode outputting a warning when debugging:
[app name] was compiled with optimization - stepping may behave oddly;
variables may not be available.
And the warning is correct, debugging is broken in this situation.
Likely caused by Clang treating -Og as -O1:
