Cannot zoom in and out of nib in the new Interface Builder
I filed a bug report a week or two ago - in short, they're aware of it.
I won't paste the email here as it said it was under NDA.
Here's hoping for 4.0.3 or similar with some zooming :)
Xcode 4.2 and no zoom and needed it badly.I have used the OS zoom: - no better alternative
For those of us who come upon this question because they removed the +/- in Xcode 6 Interface Builder, you can do it from the Editor menu, or if you have a trackpad, using pinch gestures works too. See attached SS. --Edit-- This is only for Storyboards. Zooming is still gone for individual nibs.
