Swift Syntax and Tutorial

Basic Syntax and Data Types

// Variables and Constants
var name = "John"  // Variable
let age = 25       // Constant

// Data Types
var score: Int = 100        // Integer
var price: Double = 99.99   // Double
var isAvailable: Bool = true // Boolean

Control Structures

// If-Else Statement
let temperature = 30
if temperature > 25 {
    print("It's hot!")
} else {
    print("It's cool!")
}

// Loops
for i in 1...5 {
    print(i)  // Prints 1 to 5
}

var count = 0
while count < 3 {
    print(count)
    count += 1
}

Functions

// Function Declaration
func greet(name: String) -> String {
    return "Hello, \(name)!"
}
print(greet(name: "Alice"))

Optionals

var optionalName: String? = "John"
