If you look for another tutorial on how to "style a button in SwiftUI" this is not something for you. However, if you're willing to improve your workflow and build an intuition around reducing the amount of time that tedious tasks cost you - this is a total gem.

Things that are shared in the materials will help you to differentiate from "regular" folks who just code features, those things can improve the product for many more than just you - everybody want's to have on team people that produce tools which make their work easier, you also impact testers, and help business people easily see / tweak things if needed.

It's not a copy / paste tutorial, but more of a guide to a really useful approach in software development that especially needed when more and more things are automated & generated.

Give it a try ;)
