How to set CGBITMAP_CONTEXT_LOG_ERRORS environment

问题:

While using CGBitmapContextCreate I get error in XCode

CGBitmapContextCreate: unsupported parameter combination: set CGBITMAP_CONTEXT_LOG_ERRORS environmental variable to see the details

How can I set this var?

I tried launchctl setenv CGBITMAP_CONTEXT_LOG_ERRORS /Users/user/Documents/cgbitmap_errors.log and launchctl setenv CGBITMAP_CONTEXT_LOG_ERRORS 1 and restarting XCode with no success.

I also tried combination with defaults write com.apple.dt.Xcode UseSanitizedBuildSystemEnvironment -bool NO, no success too

I restarted computer too

Environmental variables can be set in the product scheme editor (in Xcode) like shown in the screenshot:

Product > Scheme > Edit Scheme... (⌘<)
