How to Define an Enum

Group related values with enums.

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

enum Direction {
    case north
    case south
    case east
    case west
}

let heading = Direction.north
print(heading)

Notes

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