'Table' is unavailable in iOS

https://developer.apple.com/documentation/swiftui/table

Following the documentation above to build a test table, but I am getting the below errors on the first table:

1. 'buildBlock' is unavailable in iOS
2. 'init(_:columns:)' is unavailable in iOS
3. 'Table' is unavailable in iOS

Xcode version: Version 13.2.1 (13C100)
MacOS 12.1

Not sure what these errors mean, any help would be greatly appreciated.

Thanks!
