FlowForm bindings

The FlowForms iOS library is designed to simplify the process of handling form data in your Swift code. It provides a function that allows you to bind a publisher in your Swift code with the real-time status generated by the FlowForm.

    formModel.form.bindStatus(withPublisher: &$formStatus)

The above code allows you to observe the status of the formModel and determine whether it is valid (i.e., when all the fields are valid).

Fields binding

Also there are functions that allow us to bind the form fields to swift @Published variables and react to them directly from the view

     var username: Binding<String> {
        formModel.form.bind(
            fieldValue: formModel.username,
            id: FormModel.companion.USERNAME
        ) {
            self.formModel.username = $0
            self.objectWillChange.send()
        }
    }

The above code allows you to observe and bind the `formModel.username` field with its ID, enabling it to update in real-time. Additionally, it validates its content using the `validateOnValueChange` feature.

Switcher binding

For switcher controls, we have a special function that allows you to observe the termsAccepted state and react to it:

     var termsAccepted: Binding<Bool> {
        formModel.form.bindSwitch(
            field: formModel.termsAccepted,
            id: FormModel.companion.TERMS_ACCEPTED
        ) {
            self.formModel.termsAccepted = $0
            self.objectWillChange.send()
        }
    }

This code example demonstrates how to bind the formModel.termsAccepted with its ID, allowing you to observe the switcher's state changes and react to them in real-time.
