Swift Environment Setup

Installation Options

🔹 Installing Xcode (Recommended)

Xcode is the official IDE for Swift development:

🔸 System Requirements:

• macOS: 12.5 or later
• Storage: 15GB free space
• RAM: 8GB recommended

🔹 Creating Your First Project

Start a new Swift project in Xcode:

// This code appears in ContentView.swift
import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            Text("Hello, World!")
                .font(.largeTitle)
                .foregroundColor(.blue)
            
            Button("Tap Me!") {
                print("Button was tapped!")
            }
            .padding()
        }
    }
}

🔹 Swift Playgrounds (Beginner Friendly)

Perfect for learning Swift without complex setup:

🔸 Getting Started with Playgrounds:

// Try this in Swift Playgrounds
import UIKit

// Variables and constants
var greeting = "Hello"
let name = "Swift Learner"

// String interpolation
let message = "\(greeting), \(name)!"
print(message)

// Simple function
func addNumbers(_ a: Int, _ b: Int) -> Int {
    return a + b
}

let result = addNumbers(5, 3)
print("5 + 3 = \(result)")

🔹 Testing Your Setup

Verify everything works correctly:

// Complete test program
import Foundation

// Test basic Swift features
print("=== Swift Environment Test ===")

// Variables and types
let version = "Swift 5.9"
var isWorking = true

print("Language: \(version)")
print("Status: \(isWorking ? "Working!" : "Not working")")

// Arrays and loops
let frameworks = ["UIKit", "SwiftUI", "Foundation"]
print("\nAvailable frameworks:")
for framework in frameworks {
    print("- \(framework)")
}

// Functions
func calculateArea(width: Double, height: Double) -> Double {
    return width * height
}

let area = calculateArea(width: 10.0, height: 5.0)
print("\nArea calculation: \(area) square units")

print("\n✅ Swift environment is ready for development!")
