Filling out forms easily using Focus and Submit

Filling out forms can be tedious if the user has to manually click on each field, fill it out, and then click on the next field. An easier and faster way would be to use a button on the keyboard to navigate from one form field to the next.

In this recipe, we will create an address form with easy navigation between the various fields.

Getting ready

Create a new SwiftUI project named FocusAndSubmit.

Check the project's build settings and make sure the iOS target version is set to 15.0 or higher.

How to do it…

We add some text fields for various address fields within a VStack component and use @FocusState to navigate between them and submit the filled-out form at the end. The steps are given here:

1. Open the ContentView.swift file and add an enum for the fields of an address:

   struct ContentView: View {
       enum AddressField{
           case streetName...
