⚠️ Compiler Error

This week's theme: Swift Actors!

  1. Actors are a reference type distinct from classes that enable thread-safe access to the data within the actor by gating access behind async members.
  1. Actors can be used from Objective-C so long as the type is marked with @objc, and only non-isolated and asynchronous methods are called.
  1. Actors can be accessed from non-asynchronous code within the same module so long as only let properties or non isolated methods are called.
  1. Actors are implemented using special GCD queues and locks under the hood at compile time, minimizing bugs that arise from incorrect usage of isolated properties.
