9.3.0 not working with Xcode 15.4 Swift 5.10

Created brand new project using Xcode 15.4 Swift 5.10. Builds fine. Once I add CoreStore 9.3.0 using Xcode's SPM, I get 500+ errors. 
If I downgrade from 9.3.0 to 9.2.0 it works fine. 
I don't see anything in the changelog or readme that says my current setup won't work with 9.3.0

What am I missing? Thanks
