Since ios 8.0 views have additional layoutMargins which by default has an 8 points values for every side.
When I try to change margins in viewDidLoad it seems to have no effect on the child views:
override func viewDidLoad(){
super.viewDidLoad()
self.view.layoutMargins = UIEdgeInsets(top:100, left:100, bottom:100, right:100)
}
..itd does not seem to have any effect and

Overview. Edge inset values are applied to a rectangle to shrink or expand the area represented by that rectangle. Typically, edge insets are used during view layout to modify the view's frame. Positive values cause the frame to be inset (or shrunk) by the specified amount.
A layout guide representing the view's margins.
Layout margins provide a visual buffer between a view's content and any content outside of the view's bounds. The layout margins consist of inset values for each edge (top, bottom, leading, and trailing) of the view.

You are trying to set the layout margin of a root view of a view controller. The root view behaves differently than any other view in the hierarchy in regard of the layout margins.
Layout margins of a root view are managed exclusively by the view controller, you can not set them.
From Apple documentation:
If the view is a view controller’s root view, the system sets and manages the margins. The top and bottom margins are set to zero points. The side margins vary depending on the current size class, but can be either 16 or 20 points. You cannot change these margins.
