This is an experiment to create a Swift UI library based on Qt6. As research, this is a tiny todo application using Swift 6.2 and Qt6 widgets made usable in a safe way (e.g. using Swift's concurrency)
Some constraints I set for this experiment:
- No additional tooling or build systems - let's try to use only swift features.
- No additional dependencies - let's see if the effort required to write out the wrappers is acceptable for a standalone, dependency-free package.
Currently it builds on macOS and Linux, but the goal is to focus more on Linux and Windows as target platforms where SwiftUI/AppKit are not available.

QwiftUI- the libraryQtBridge- bridging between Qt6 and Swift based on C++ interop, abstraction for event handling and other facilities to make using widgets easier and safer.QwiftUITest- testing helpers to wrap around Qt TestQtDemo- simple demo app to run experiments, this will be refactored to depend on QwiftUI.Qt6AppBackend- target in which we try to implement a Qt backend for SwiftCrossUI https://github.com/stackotter/swift-cross-ui/blob/main/Sources/SwiftCrossUI/Backend/AppBackend.swift
This is hardcoded for now:
The Package.swift is configured to expect the qt6 headers in a location used by Homebrew (brew install qt): opt/homebrew/Cellar/qt/6.9.1 for macOS
On Linux, the path is set to /usr/include/qt6 which is the default on Fedora.
