How to Work with Arrays

Create, update, and iterate arrays 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

var fruits = ["Apple", "Banana"]
fruits.append("Cherry")

for fruit in fruits {
    print(fruit)
}

Notes

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