This approach doesn't make sense. You're *immediately* removing the old view,
replacing it with the new view, and then trying to fade in/out the two.
You need both views to be in the window for the entire duration of the
animation. That means the new view must be in the window before the animation
starts, and the old view can only be removed after the animation ends.
Instead of swapping out the content view of the window, you need to add these
views as subviews of the content view, fade them as desired, and resize the
window as needed.
