How to Write a For-In Loop

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 names = ["Ava", "Liam", "Noah"]

for name in names {
    print("Hello, (name)")
}

Notes

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