If you look below, you'll also see an element called that describes the change in position based on the size class. In order to fix the position for this, we have to use the following steps:

1. Take a look at the warning that shows up in Xcode. Take note of what needs to be changed for that UI element.
2. Open the storyboard in an external (text) editor.
3. Find the UI element in the storyboard.
4. Change the value to match what the warning is suggesting in both and .
5. Save the file in the external editor.
6. Go back to Xcode. Let it re-calculate all the constraints.
7. Accept the warning for the UI element that pops up again.
8. If you go back to the external editor, you'll notice that the element is gone.
