I’m following the tutorial and have downloaded the images etc. I know the version I’m using is newer, so things are slightly different. I have adjusted background image to “scale to fit” but doesn’t turn out how it does in tutorial. I can change image size manually yes, but think it causes issues moving forward.
The other thing that you probably should do is embed the label and the 3 buttons into a StackView since that offers some streamlining in terms of the spacing of each element and it will line up each item so that they have the same width as in my version above.
It also means that you only have to apply 1 set of constraints to position the StackView and the elements embedded within it will align to the edges of the StackView.
