I'm following the Build an app with SwiftData from WWDC 2023. I'm using the Xcode release candidate for Xcode 15. i'm running the Developer Beta for Sonoma. The first change was to import SwiftData, add the @Model macro to the Definition for the Card object and remove @Published from two variable in the definition. After doing this I get 5 errors: External macro implementation type 'SwiftDataMacros.PersistentModelMacro' could not be found for macro 'Model()' The instructions continue to the CardEditorView and change the macro for var card to @Bindable with the error 'init(wrappedValue:)' is unavailable: The wrapped value must be an object that conforms to Observable Then we move to the App main class where we add .modelContainer(for: Card.self) and get the error No exact matches in call to instance method 'modelContainer' Any clue why this is happening?
