I'm trying to start using Xcode Cloud from a project, but the only thing I get is the message saying "Failed to create workflow" with the actual error being "Could not find item. Domain: XcodeCloudKit.XcodeCloudCommandHandler.CommandHandlerError Code: 5". Initially, it did lead me to configuring permissions on GitHub. But it failed in the end probably because the git remote of the project was pointing to another organisation, that transferred the ownership to me. I switched remote to my org, but it didn't help. So, I revoked the permission and deleted Xcode Cloud app from my GitHub in hopes that the config process would start again. It does not. All I get is this senseless error. Is Xcode Cloud functionality functioning at all in Xcode beta 27 for anyone?

The 'Sea Creator' sample app demonstrating Safari Web Extensions first fails to compile, because due to disambiguation extension bundle id isn't prefixed with app bundle id. When fixed by changed ids the app fails on start, with error saying that the app can't find extension. Regardless, extension works on its own in Safari, but can't communicate with the host app due to aforementioned error.

Trying to test StoreKit purchases in our existing game from Xcode ends in failure. I have created a couple of consumable purchases which mirror the real ones, but an attempt to buy any one of them on a device (not simulator) ends in error "Purchase failed: unable to communicate with a helper application". This happens right after payment confirmation screen. This is on the first iOS 14 beta and first Xcode 12 beta. Any suggestions on how to work around that are welcome.
