I recently updated to Xcode 7.3 , however while debugging at break points , the objects show in the debug area but clicking the triangle to reveal the variables does nothing
Phew ..
The pictured setting did it for me .
Also a Option Clean Build is imperative after making the changes .
Only changing the Clang Module Debugging also works , but halting at breakpoints displays a warning .
"could not load any Objective-C class information from the dyld shared cache"
Other observations : When changing the build settings back to original , clicking the triangle the variable values do still show (from memory I guess) for the last breakpoint (from the altered settings) , but variables at other breakpoints don't .
Again , Never had such issues with prior versions of Xcode .
Edit :
The DWARF setting can be avoided . Works fine without it .
Edit :
Also if you are using Cocoapods , you might need to recreate the xcworkspace .
