Tuples with Pattern Matching in Swift

.swift

import Cocoa

func processCoordinates(coordinates: (Double, Double)) {
    switch coordinates {
    case (0, 0):
        print("You're at the origin!")
    case (let x, 0):
        print("You're on the x-axis at \(x)")
    case (0, let y):
        print("You're on the y-axis at \(y)")
    case (let x, let y):
        print("You're at coordinates (\(x), \(y))")
    }
}

// Call the function with different tuples
processCoordinates(coordinates: (0, 0))        // Output: You're at the origin!
processCoordinates(coordinates: (3, 0))        // Output: You're on the x-axis at 3
processCoordinates(coordinates: (0, 5))        // Output: You're on the y-axis at 5
processCoordinates(coordinates: (2.5, 3.5))    // Output: You're at coordinates (2.5, 3.5)
