For more information on the Delegation pattern used by Apple, see the relevant link in the Further reading section.

To implement our UITextViewDelegate, we'll need to make the following changes. We'll continue this with the TestRepresentableView we started earlier.

Inside the TestRepresentableView struct, create a class called Coordinator. This will need to extend NSObject, as well as the delegate we want to use (in this case, UITextViewDelegate):

class Coordinator : NSObject, UITextViewDelegate

Once created, we'll need to add a property called parent that will be of the TestRepresentableView type. This is our link to the parent view from our coordinator:

var parent: TextView

Next, we'll add the highlighted initializer for our coordinator:

var parent: TextView
