How to Use Optionals Safely

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 nickname: String? = "Ace"

if let name = nickname {
    print("Nickname: (name)")
} else {
    print("No nickname")
}

Notes

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