Thank you Kyle. I'm taking a look at the layout. I have a question. I don't need to auto-align the NSView. I need to let the user enter origin and size of the view (excluding the shadow and frame) and get the view on those coordinates and size.
Let's say I learn how to configure the layout with e.g. setTranslatesAutoresizingMaskIntoConstraints, alignmentRectInsets, alignmentRectForFrame, frameForAlignmentRect and such... Then which properties should I bind to the NSStepper and NSTextFields on the UI in order to place the view with the right origin and size?
