Defensive Programming

  • Wallace Wang

Abstract

Programmers tend to be optimistic because when they write code, they assume that it will work correctly. However, it’s often better to be more pessimistic when it comes to programming. Instead of assuming your code will work the first time, it’s safer to assume your code won’t work at all. This forces you to be extra careful when writing Swift code to make sure it does exactly what you want and doesn’t do anything unexpected.
