Where is the "Canvas" option in Xcode?

Question

I'm new to Xcode and when reading a tutorial, it tells me to do this in my storyboard file:

First, click on the view controller and go to Editor > Canvas > Show Bounds Rectangles

I'm with the interface builder opened but I can't see where is the "Canvas" option (or menu, I don't know).

Answer 1

Canvas option (under Editor) is only available if you have a .xib file selected in Project Navigator.
