Xcode 27 beta 4: how do I create a local package for my project? The menu path File > New > Package no longer exists.

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?

"To upload app preview, you must use Safarin and OS X 10.10" - this error pops when I'm trying to upload a video.Obviously, I am.The video file is MOV, portrait 1080x1920, H.264. if anything is wrong with the video, the error don't tell me that.Anyone seen anything like that before?

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.
