Swift macros, a new powerful language feature for optimizing compile time and app size, was introduced WWDC 2023 🎉 From zero to hero 🦸🏾‍♀️, let’s save (optimize) our app size. In this talk, thetealpickle will introduce the concept and then we’ll live code some macros 🤤. During the live coded portion of this talk, we will help save a Rick and Morty themed multidimensionally used app, `Poopybutthole`. From exploring and implementing various macros use cases to writing tests for our macros. We will also create custom diagnostics and fix-its to help the future maintainers of `Poopybutthole`. ✨ It’s time to get schwifty with macros, join the fun 🚀
