Swift Language Bindings for WinUI

APIs

These projections contains the WinUI APIs which are part of the Windows App SDK, (i.e. Microsoft.UI.Xaml.*). See official documentation for more information on these components:

• API Docs
• Official GitHub repo

Due to SPM limitations and the current state of swift-winrt, not all APIs can be generated as this causes export limit issues.

SDK Versions

1. Windows SDK: 10.0.18362.0
2. Windows App SDK: 1.5-preview1

Project Configuration

The bindings are generated from WinMD files, found in NuGet packages on Nuget.org. There are two key files which drive this:

1. projections.json - this specifies the project/package and which apis to include in the projection
2. generate-bindings.ps1 - this file reads both packages.config and projections.json and generates the appropriate bindings.

Filing Issues

Please file any issues you have with this repository on https://github.com/thebrowsercompany/swift-winrt

Known Issues and Limitations

• Only x64 architecture is supported for now

• The developer experience for consuming WinRT APIs from Swift is a work in progress. Due to current limitations, not all APIs can be generated as this causes export limit issues.

• The APIs listed in projections.json are required for the other swift-* projects to build. Modify a projections.json in any one of those projects could require an update here.

Using WinUI

In order to use WinUI, you need to download the Windows App SDK from here: https://aka.ms/windowsappsdk/1.5/1.5.240205001-preview1/windowsappruntimeinstall-x64.exe
