Initialized empty Git repository in /host/spi-builder-workspace/.git/
hint: Using 'master' as the name for the initial branch. This default branch name
hint: is subject to change. To configure the initial branch name to use in all
hint: of your new repositories, which will suppress this warning, call:
hint:
hint: git config --global init.defaultBranch <name>
hint:
hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hint: 'development'. The just-created branch can be renamed via this command:
hint:
hint: git branch -m <name>
From https://github.com/wabiverse/swift-cross-ui
* branch main -> FETCH_HEAD
* [new branch] main -> origin/main
HEAD is now at 1a887c2 appkit: mark makeCoordinator with MainActor. * The appropriate method that should NOT have a main actor is determineViewSize, since that will break compiling with swift 6 strict concurrency.
