The first image shows the constraints on the bottom container view. "Bottom space to superview" is set to 0. I want the container to be anchored to the bottom of the screen no matter what the screen height.
I do not want a constraint on the distance from the bottom container view to the top of the screen, but Xcode is creating one automatically (top space to superview = 508) and won't let me delete it. Why is it doing that? My container view's position is fully defined by the other 3 constraints and its height (60 px).
More importantly, when I run the application, the container view does not fit on screen. It is partly cut off. The bottom of the container view is cut off even though "bottom space to superview" is constrained to be 0. What is going on?
