Screenshot of an email that reads "Hi there (this is for Natalia) — I just wanted to say thanks for writing the SwiftUI books — I’ve been working on my own apps for a few weeks and kept running into walls and warnings and a great deal of frustration — I knew I was approaching the app’s construction wrong, but couldn’t figure out how. I saw your books mentioned in a newsletter, bought them... and the explanations of view identity and data flow made sense in a way that just hadn’t gotten through to me no matter how many other tutorials or bits of Apple documentation I read. I’m not even 20% through the first one and I’m already so much better off. Thanks again, and really, great job on the writing. It’s so clear and easy to follow, and makes it so much easier to think in a model that works with SwiftUI instead of against it. I will be recommending them to anyone I run across who needs help. Well done!"

Got the nicest feedback about my SwiftUI books, it made me really happy 🥰
