Creating our layouts with UIStackView

Now we've got the foundations all set up, let's look at how we are going to build our details page.

We have several options. One way is Autolayout, which is exceptionally powerful and will certainly give us what we need. However, there is a much simpler way we can achieve this, by using a powerful component called UIStackView.
