No so straightforward, but there is project that parses xcodebuild logs and pass them to lsp to provide LSP for SwiftUI projects https://github.com/SolaWing/xcode-build-server

Also I build extra tooling to facilitate iOS development in VSCode https://github.com/sweetpad-dev/sweetpad

Thanks for your great work on sweetpad. I’ve always been a bit curious where the name came from though.
