How to Use Access Control

Restrict visibility with public, internal, and private.

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

struct Profile {
    private var token: String
    let name: String

    init(name: String, token: String) {
        self.name = name
        self.token = token
    }
}

Notes

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