xCode 6 - Corrupt Breakpoints (Limited Variables / Chinese Characters)

Question

My xCode 6 Swift Project breakpoints don't seems to be working correctly.

When placing a breakpoint in any method the variables are either blank or populated with Chinese characters (see below).

I believe there must be a corruption with my target because earlier today I ran my Today Widget and this works correctly and can see the variables and contents BUT when running my main target I get what you see in the image below.

Please help this is driving me mad!!!

For anyone getting the same issue / coming across this stack post. I fixed the issue by changing the Optimization Level all to None instead of "Fastest, Smallest [-Os]".
