Adding Auto Layout


If we do not add Auto Layout to our cells, they will not look correct; so, let's do that now:

  1. Open RestaurantDetail.storyboard.
  2. Next, select the Container View, the one used for reviews, and then the Pin icon. Enter the following values:
    • Top: 0
    • Right: 0
    • Bottom: 0
    • Left: 0
    • Constrain to margins: Unchecked
  1. Click Add 4 Constraints.
  2. Now, select the Collection View, the one used for reviews, and then the Pin icon. Enter the following values:
    • Top: 0
    • Right: 0
    • Bottom: 0
    • Left: 0
    • Constrain to margins: Unchecked
  1. Click Add 4 Constraints.

Build and run your project and add a couple of reviews; you should now see reviews appearing in your restaurant details:
