Create a standalone view in storyboard to use programmatically

I'm trying to create and design a UIView using a storyboard but include it in a UIActionSheet programmatically. This is basically to avoid using CoreGraphics positioning functions with pixels

In old xcode I remember that it was possible to drag a UIView onto the nib without any controllers.

The view obviously has to be connected to the class, so it would have an IBOutlet, but not being added to the self.view

One thing that makes me feel like this should be possible is that if you drag a UIView into the controller black bar in storyboard it pops into place like so:

But its not shown on the screen itself. What is this feature for? Can I somehow open up this view and design it a bit?
