📓
Scenario:
Just found some environment variable in the build phase tab (or other tabs) in Xcode project setting and what do these variables mean?
Solution:
When we work with a workspace ,use the command xcrun xcodebuild -workspace XXXXX.xcworkspace -scheme XXXXX -showBuildSettings to show these variables.
Other than workspace, we use -project options with project like xcrun xcodebuild -project myProj.xcodeproj -target "myTarg" -showBuildSettings
