There are quite a few projects failing at this point.
GRDB and ObjectMapper are known issues that I have been trying to XFAIL but that's now being foiled by the other issues showing up yesterday (see XFAIL GRDB and ObjectMapper by rudkx · Pull Request #127 · apple/swift-source-compat-suite · GitHub).
I see two new issues across various projects:
BlueSocket, IBAnimatable, Kingfisher, Kronos, NetService, SwiftLint
