A complete guide to the SwiftUI framework. Content is up to date with all the new features introduced during the latest WWDC (2021).

Companion for SwiftUI is an interactive documentation of all the SwiftUI views, shapes, protocols, scenes, styles, property wrappers and environment values found in all platforms (iOS, macOS, tvOS and watchOS).

The application includes an example for each method. A great deal of them are interactive and run embedded in the app. By using the associated controls, you'll see the immediate effects it has on the views, and how the code changes to produce such results.

Examples may be copied and pasted in Xcode, and are ready to run.

Whether you are working on a legacy project, or learning the new additions from WWDC '21, you may create filters that hide the irrelevant areas of the API. You may have multiple tabs open, each with a different filter.

You don't know what the control point in a quad curve is? No problem, open the .addQuadCurve() entry and drag the points of the curve to see how the parameters of the function change. It's instant knowledge, that will accelerate your learning curve dramatically.

This should be bought by Apple (for an very large amount of money) and integrated directly into XCode.

This is by far the most useful documentation for SwiftUI that I have found.

I have been developing for Apple since 1985 and have always found thier documentation - uh - crypic - to be kind. It is fine, if you already know what you want and are just verifying something, where this product provides answers and examples in a clear manner that is easy to find and use.

Paid for itself almost immediately

I spend way too much time searching Google and Stackoverflow for answers to SwfitUI questions. I put off buying this app because of the price, but after hitting page three on Google and still not being able to find the answer to my question I finally decied enough was enough. I bought the app and within 2 minutes found the answer and solved the problem. This is going to change my life.

Absolute Must Have for SwiftUI Development

I'd rate this application (and the companion WebSite) 100 stars if I could. The documentation is clear and concise and the examples perfectly demonstrate each use case.

I have used it almost every day for the past 18 months. There is no way I could have figured out much of SwiftUI without this tool. It's rock-solid and accurate; simply amazing!

Thank you!
