How to add top-level restrictions and disable translatesAutoresizingMaskIntoConstraints in the interface of the Builder.xib file

When loading a UIView from a nib file, the view is usually translatesAutoresizingMastIntoConstraintsset to YES.

As a result, you cannot add top-level constraints to the view (for example, width and height).

In the past, I was able to create a top-level view that allows me to create top-level constraints and sets translatesAutoresizingMastIntoConstraintsto NO.

How can I get this behavior when loading a UIView from nib without subclassing it?
