Live Layout Inspector

Debug your layout with an updated Live Layout Inspector that provides complete, real-time insights into your app's UI while it's deployed to a device. Along with many of the same features of the existing Layout Inspector, the Live Layout Inspector also includes:

• A dynamic layout hierarchy that updates as the views on the device change.
• A property values resolution stack to drill into resources right from the view.
• Advanced 3D visualization of an app's view hierarchy at runtime.

For more information, see the release notes.
