About the Debug Navigator

The debug navigator displays the call stacks of your paused app. With this navigator you can debug C-based code and OpenGL frames.

Selecting an item in the debug navigator causes information about the item to be displayed in the editor area and in the debug area.

Debugging C-based Code

When debugging C-based code, the navigator groups the stack frames by threads or queues, and lists the memory locations you’re interested in. Use the debug navigator to navigate the stack frames of your app’s threads, and to manage viewed memory locations for the current debugging session.

The debug navigator opens automatically whenever you pause your application (by choosing Debug > Pause), or it hits a breakpoint. (You can change that behavior in Alerts preferences.)

Note: The debug navigator shows content only when your application is paused.
