Just upgraded to Xcode 13.3 beta 3 (from Xcode 13.2.1) and ran swift package init. It generated a deprecation warning, I have not seen this before:
warning: Usage of /Users/sajjon/Library/org.swift.swiftpm/collections.json has been deprecated. Please delete it and use the new /Users/sajjon/Library/org.swift.swiftpm/configuration/collections.json instead.
But I do not know HOW to "use the new ... instead"? In fact I don't even know how or when org.swift.swiftpm/collections.json was created.
What to do?

Creating library package: DeleteMe
Based on a comment from @jalone, this may cause Xcode to crash upon opening the project. It did not do that in my case but all I had was the generic Apple collections: https://developer.apple.com/swift/packages/collections/apple.json
Proceed with caution
It looks like all I needed to do is run this to get rid of the warning.
rm ~/.swiftpm/config/collections.json
There should be an additional collections.json located at ~/.swiftpm/config/configuration/collections.json that is where the packages are now stored when you use
swift package-collection add <package.json>
For more information see the SE proposal documentation here
The warning says that you need to delete the file.
Please delete it and use the new /Users/sajjon/Library/org.swift.swiftpm/configuration/collections.json instead.
So please delete it and it will help.
