<!DOCTYPE html>
<html>
<head>
  <title>My iOS Web App</title>
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <h1>Welcome to My iOS Web App</h1>
  <p>This is a simple web app for iOS devices.</p>
  <script src="script.js"></script>
</body>
</html>

Styling with CSS

Next, create a CSS file (e.g., style.css) to add some style to your web app. Here's a basic example:

body {
  font-family: Arial, sans-serif;
  background-color: #f0f0f0;
  text-align: center;
}

h1 {
  color: #333;
}

Adding Interactivity with JavaScript

Create a JavaScript file (e.g., script.js) to add interactivity. Here's a basic example:

alert("Hello, iOS Web App!");

Testing and Deployment

Save the files and open the index.html file in your Safari browser on your iOS device or simulator. You should see your web app with the text and the alert box.
