- [Instructor] One of the most frustrating things about working with layout constraints is debugging them in code. Luckily Xcode lets us add identifiers to our constraints to make finding them a little bit easier. Let's go into the storyboard and select the newsletter view from the document outline. We want to find its height constraint, so we'll go into its sub folder called Constraints, select height. Make sure the Utilities panel is open and that we're in the Attributes Inspector tab.
