👋 FirstSwiftUI

A beginner iOS app built with SwiftUI that introduces core declarative UI concepts including state management, text input, buttons, toggles, and sliders — all in a single composable view.

---

✨ Features

• Welcome Image — Displays a custom image at the top of the screen
• Text Field Input — User enters their name with a rounded border style
• Show Greeting Button — Tap to reveal a personalized greeting
• Toggle Switch — Alternatively show or hide the greeting using a UISwitch-style toggle
• Font Size Slider — Dynamically adjust the greeting's font size from 10 to 50pt in real time
• Conditional Greeting — Displays "Hello, [name]!" (or "Hello, World!" if no name is entered) with a green border

📖 Concepts Demonstrated

This project is a hands-on introduction to foundational SwiftUI concepts:

• Using @State to manage local view state reactively
• Two-way data binding with $ (binding syntax) for TextField, Toggle, and Slider
• Conditional rendering with if inside a View body
• Composing built-in SwiftUI views: VStack, Image, TextField, Button, Toggle, Slider, Text, Spacer
• Applying modifiers like .font(), .fontWeight(), .padding(), and .border()
