Did anyone successfully used transformable in SwiftData to store UIColor or SwiftUI Color type? @Attribute(.transformable) var color: UIColor

If I make model changes in the mainContext using a batch operation like context.update OR on a background thread ModelContext ModelContext(container), my saved changes are not automatically reflected in the UI (a List of models). Also ModelContext.willSave and ModelContext.didSave don't seem to get called. Will automatic UI updates work in an upcoming Beta but are NOT in Beta 1? Or will we refresh View/@Query based on a ModelContext.didSavenotification? Or should this be working in Beta 1 and I am missing how it works?
