How to Create a Struct

Use structs for lightweight data models.

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 User {
    let id: Int
    var name: String
}

var user = User(id: 1, name: "Ava")
user.name = "Ava Lee"
print(user)

Notes

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