A dump of the SwiftUI.framework binary for the iOS simulator (as of Xcode 12.0 beta 2) using the swift-reflection-dump tool.
Note: I used a Swift 5.3 compiler build from a few weeks ago that I had laying around. Because of ABI stability, I don't think the swift-reflection-dump version has to match the compiler version that was used to build the binary, but I'm not 100% sure.

| // 1. Follow this guide (WITHOUT setting up a URL scheme in Xcode): | |

| // Implemented in a way that: | |
| // 1. The compiler generates as much code as possible | |
| // 2. You'll get a compiler error if you forget a property | |
| // | |
| // Nested support and collections left as an exercise for the reader. |
If you work on a Swift project that follows the Model-View-ViewModel (MVVM) architecture or similar, you may want to jump to counterpart in Xcode from your view to your model, and then to your view model. (ie. by using Ctrl+Cmd+Up and Ctrl+Cmd+Down).
You can do this in recent versions of Xcode by setting a configuration default.
From a terminal, just type this command and press Enter:
defaults write com.apple.dt.Xcode IDEAdditionalCounterpartSuffixes -array-add "ViewModel" "View"
