Xcode 6 how to enable storyboard zoom?

I've updated to Xcode 6 beta 3 and see that the [+ = -] buttons in the storyboard corner are gone. Is there a way for me to zoom in and out on view controllers within a storyboard in Xcode 6?

You can zoom the storyboard by double-click canvas or using top-menu(Editor > Canvas > Zoom).

Alternatively: Right click blank space on canvas and choose zoom level (allows to zoom out further than double click)

If you have a magic trackpad (external or embedded in the macbook) you can also pinch to zoom... It sounds quite obvious, but I've just discovered it.

double cick is best for zooming IN and OUT... just do a DOUBLE CLICK in the story board in Xcode 6
