# Lightweight Form Validation in SwiftUI: A Property Wrapper Approach That Actually Works

Form validation in SwiftUI has always been a pain point. Most solutions either require you to wrap every input in custom controls, pollute your views with validation logic, or force you to use heavyweight third-party libraries. What if there was a simpler way?

In this article, I'll walk you through a lightweight form validation approach that leverages Swift's property wrappers and SwiftUI's view modifiers to create a clean, type-safe, and extensible validation system. No custom controls required.

## The Problem with Existing Approaches

Before diving into the solution, let's acknowledge why form validation in SwiftUI is challenging:

import 'package:flutter/widgets.dart';

// MARK: - Iterable Extensions

extension FlutterishIterable<T> on Iterable<T> {

  List<Widget> toWidgets({
    required Widget Function(T element) itemBuilder,
    Widget Function()? separatorBuilder
  }) {
