Xcode Visual Debugger

Built on the powerful LLDB debugging engine, the Xcode visual debugger in Xcode 5 is cleaner and more readable, and the Data Tips that hover over your code are more responsive. Variables in either view are formatted to be easier to understand at a glance, and you can now use Quick Look to quickly peek at an image, web page, bezier curve, or a document in memory. You can even print the object within the editor using a single click.
