How to Read User Input from the Console

Use readLine to capture simple input in CLI tools.

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

print("Enter your name:")
if let name = readLine() {
    print("Welcome, (name)!")
}

Notes

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