Answer 1

When you are using auto-layout, the subviews are laid out after the viewDidLayoutSubviews function. Therefore, if you call tileContainer.frame.size before that, such as in viewDidLoad, it will always be 600 by 600 (which is the default size in storyboard).

viewDidLayoutSubviews: Called to notify the view controller that its view has just laid out its subviews. reference

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    print(tileContainer.frame.size); // This is actual size you are looking for
}
