SwiftUI forms

SwiftUI provides several form controls that we can use to get input from the user.

Think about the Settings app on your iPhone.

That app can be built using the built-in form controls that we’re going to soon see, like:

• TextField
• Toggle
• Picker
• and others

All of those are going to be wrapped in a Form view:

Form {

}

This tells SwiftUI that this is a form, and SwiftUI will present the content in a way that it conforms to how a form should look, on the specific platform you run it on (iPhone, Mac, Watch..).

This is part of the declarative aspect of SwiftUI. We wrap our form controls in a Form view to tell it it’s a form, then it makes decisions for us.

We’ll see more about forms by covering each individual form control.
