Find the ${PROJECT_DIR} for an Xcode project

Question

How do I figure out what my absolute ${PROJECT_DIR} path is for my Xcode project? Is there a way to print this in Terminal? How?

Answer 1

Build Settings -> Preprocess Macros

PROJECT_DIR=@\""$PROJECT_DIR"\"  BUILD_ROOT=@\""$(BUILD_ROOT)"\" 

Then you can log it directly

NSLog(@"project dir=%@, BUILD_ROOT_=%@", PROJECT_DIR, BUILD_ROOT); 

Answer 2

Run this from Terminal

For a project:

xcodebuild -project yourProject.xcodeproj -target yourTarget -showBuildSettings | grep PROJECT_DIR 

For a workspace:

xcodebuild -workspace yourWorkspace.xcworkspace -scheme yourScheme -showBuildSettings | grep PROJECT_DIR 

As you can see, you can retrieve any other build settings value
