Notes on this fork

This fork of compnerd/SwiftWinRT contains some work I've been doing toward automatic generation of the Swift bindings for WinRT. It has changed very significantly from the original repo.

There are five SwiftPM packages here:

  • WinRT contains the core definitions for supporting IInspectable and such. It is largely similar to the original repo.

  • WindowsSdk contains automatically generated bindings for a bunch of WinRT things in the Windows SDK.

  • WindowsApp contains automatically generated bindings for a bunch of WinRT things in the Windows App SDK.

  • Win2D contains automatically generated bindings for Win2D.

  • Samples contains several sample apps.

None of the generated bindings are complete. Generally speaking, I can generate bindings for any of the WinRT types in Windows SDK, Windows App SDK, or Win2D, and the resulting Swift code will compile. However, the size of the result is so large it causes the Windows linker to fail because of the 65,536 symbols limit. I'm still investigating ways around this.

The two original samples are still here and have been modified a little bit to build with the new bindings.

A new toast notification sample has been added.

The most complete sample is MazeGame, a Swift port of the Win2DMazeGame sample from Microsoft. It uses WinUI3 for a simple GUI shell and Win2D for the game itself.

I'm using Swift 5.6.1, and I have not tested with any other version.
