Creating new question label constraint


I think the following instruction is incorrect:

Then Control-drag upward from the nextQuestionLabel to its superview and select Center Horizontally in Container.

When I Control-drag upward, I can “Center Vertically in Container.” If I want “Center Horizontally in Container,” I have to Control-drag sideways.

Which is correct? Should this be in the errata?


Control-drag sideways to select “Center Horizontally In Container”, since that was the intended consequence. This should be in the errata.
