• Protocol-Oriented Programming
  Protocol-oriented programming enables writing code that is more modular, decoupled, and flexible, compared to traditional object-oriented programming. Not surprisingly, protocols are at the heart of protocol-oriented programming. In this article, I'll explain what protocol-oriented programming is and how to adopt this paradigm using protocols to define requirements and provide default implementations, while also ensuring optimum performance.
  
  
• Capture Lists
  Capture lists have been available in Swift since its debut at WWDC 2014. They play a crucial role in ensuring your asynchronous code does not leak memory or cause exceptions at runtime. In order to use capture lists correctly, you'll need a good grasp of related topics including value vs. reference types, strong reference cycles, and escaping vs. nonescaping closures. In this article, I'll cover these supporting topics first, and then explain why, when, and how to use capture lists effectively.
