The tutorial hints on page 46 suggest adding a Visual Effect Views with Blur and Vibrancy as so does the text. On page 48, we are required to add a label as a child of the Visual Effect Views with Blur and Vibrancy but it has been such a pain for me as the auto-layout is complaining of the set constraints until I checked the final project and found out the tutorial uses the Visual Effect View with Blur. Refer to the screenshot below.
Errors reported are: missing constraints for X position or width | Y Position or height.
Therefore it’s a typo and it should state the correct view used.
