Day 24: Designing Forms and Handling User Input Validation 📋 Let's go to the basics today with by creating forms and handling user input in SwiftUI. Forms are a core part of many apps for collecting data from users. Let’s jump in! Code SwiftUI provides the Formcontainer, making it easy to create user-friendly input forms. import SwiftUI

struct UserFormView: View {
    @State private var username = ""
    @State private var email = ""
    @State private var password = ""
    @State private var errorMessage = ""

    var body: some View {
        Form {
            // Username Input
            Section(header: Text("Username")) {
                TextField("Enter your username", text: $username)
                    .autocapitalization(.none)
                    .disableAutocorrection(true)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
            }

            // Email Input
            Section(header: Text("Email")) {
                TextField("Enter your email", text: $email)
                    .autocapitalization(.none)
                    .keyboardType(.emailAddress)
                    .disableAutocorrection(true)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
            }

            // Password Input
            Section(header: Text("Password")) {
                SecureField("Enter your password", text: $password)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
            }

            // Error Message

                    .cornerRadius(8)
            }
        }
        .navigationTitle("User Form")
    }

    // Step 3: Validate the form inputs
    func validateForm() {
        if username.isEmpty || email.isEmpty || password.isEmpty {
            errorMessage = "All fields are required!"
        } else if !email.contains("@") {
            errorMessage = "Invalid email address!"
        } else if password.count < 6 {
            errorMessage = "Password must be at least 6 characters!"
        } else {
            errorMessage = ""
            // Handle successful form submission (e.g., save data)
        }
    }
