FormCraftControllerView Struct

FormCraftControllerView binds a SwiftUI input control to a specific form field.

It provides:

• typed binding to field value (Binding<Field.Value>)
• access to current field object (Field)
• automatic mounted/focus synchronization
• automatic per-field validation when value changes

Constructor

init(
    formConfig: FormConfig,
    key: WritableKeyPath<FormConfig.Fields, FormField>,
    @ViewBuilder content: @escaping (_ value: Binding<Value>, _ formField: FormField) -> Content
)

Arguments

• formConfig: FormConfig - form configuration object.
• key - key path to target field in formConfig.fields.
• content - builder that receives value binding and field object.

Example:

FormCraftControllerView(formConfig: form, key: \.email) { value, field in
    TextField("Email", text: value)

    if let firstError = field.errors?.messages.first {
        Text(firstError)
            .foregroundStyle(.red)
    }
}
