UPDATE (2024): app still rocks, cannot believe they keep adding content for the app that I have purchased like 3-4 years ago. That is exactly how Apple should have done it. Love the app.

I hope All Developers Use This App

I do a lot of swiftUI and wouldn't have thought i'd appreciate it this much.

It's the documentation that Apple forgot.

I can't stress this enough. Owning this app is my proudest achievement.

If you are using and/or learning SwiftUI, getting this app will be the best $50 you spend this year. It's a tremendous resource and beautifully crafted.

This app has API docs with some sample code. That's it. There are no high-level explanations, nor really any content not available from Apple in other forms. The only value-added is navigating by API, just like XCode's docs. I bought it, looked at a few things, and now find myself never, ever opening it. It would be fine for $5-10 dollars, but the $50 price leaves me with the bad taste of a scam.

Not only did the latest update include all the new features introduced at WWDC 2022, but also includes a new menu bar search utility. This guy is brilliant and a great explainer and deserves your money. You will not be disappointed.

It's been about 20 minutes and it feels like this has already saved me hours. The writing is clear, the examples are simple and to the point, and the interactive bits make it feel like I'm cheating. Excellent example of what a tool can be.

This is a great application and is a must have for the serious SwiftUI developer. Using this app brings back the joy I used to feel using Think Reference in the days before easy Internet access. The documentation is clear and well-written and the code examples can be run and modified in a Swift playground. Save yourself the bother of searching StackOverflow and Apple documentation and go straight to this app for answers.
