struct ContentView: View {
    
    @State var email: String = ""
    @State var phone: String = ""
    
    @State var emailFailedRules: [TextValidationRule] = []
    
    var body: some View {
        FormView {
            ScrollView(.vertical) {
                FormField(
                    "Email",
                    text: $email,
                    validationRules: [.email],
                    failedValidationRules: $emailFailedRules
                )
                if emailFailedRules.isEmpty == false {
                    Text("Email")
                        .foregroundColor(.red)
                }
                FormField(
                    "Phone",
                    text: $phone,
                    validationRules: [.digitsOnly],
                    inputRules: [.digitsOnly]
                )
            }
        }
    }
}

ValidationRules are used for automatic validation of text during input. All rules that have not passed the validation come with the failedValidationRules.

InputRules are used to prevent incorrect input.

You can also use a .formView() modifier instead of FormView:

ScrollView(.vertical) {
    ...
}
.formView()
