title: safeAreaInsets return wrong values in viewDidLoad, where's the best place to get it?
body: <p>When I try to retrieve the safeAreaInsets in viewDidLoad in my view controller, it returns (0, 0, 0, 0) on the iPhone X, which I know is wrong. The documentation says that this will happen if the view is not part of the hierarchy or the view isn't visible. So my question is, where is the best place to retrieve the safeAreaInsets and then layout my subviews using these insets? </p>
