How to Use Switch in Swift

Steps

1. Paste the code into a Swift file or playground.
2. Run it once to verify the output.
3. Adjust the inputs to match your use case.

Copy and paste

import Foundation

let status = 404

switch status {
case 200:
    print("OK")
case 400...499:
    print("Client error")
case 500...599:
    print("Server error")
default:
    print("Unknown")
}

Notes

• Keep functions small and focused for reuse.
• Prefer safe APIs like optionals and guards.
