I'm looking for a hot-key, e.g. spacebar + Click 'n drag, that will enable me to use the mouse to pan Xcode Storyboard.
Obviously I can use the mouse-wheel to pan the storyboard, but it's far more tedious that clicking and dragging it to the exact location I want.
Is there a way to pan the Xcode storyboard with a click-and-drag motion?
There isn't a way to do this unfortunately... Instead, there are a couple of tips on alternatives ways of moving things around in the Storyboard in this answer here: Moving UI-elements in storyboard editor
