I have a WidgetExtension using SwiftData (same ModelContainer setup used in the WatchApp: @main struct Watch_Widget: Widget { let kind: String = "Watch_Widget" var body: some WidgetConfiguration { StaticConfiguration(kind: kind, provider: Provider()) { entry in Watch_WidgetEntryView(entry: entry) .modelContainer(for: [Model1.self, Model2.self]) } .configurationDisplayName("App") .description("descriptions") } } Here's the same model used in the widget view: struct Watch_WidgetEntryView : View { @Query var models: [Model1] var body: some View { let gaugeVal = models.count Gauge(value: gaugeVal, in: 0...60) { Text("min") } currentValueLabel: { Text(String(Int(gaugeVal))) } .gaugeStyle(.accessoryCircular) .widgetLabel { Text("\(models.count) models") } .containerBackground(.fill.tertiary, for: .widget) } } When I build the WidgetExtension, the following error was thrown and the CK data isn't loaded properly: CloudKit setup failed because there is another instance of this persistent store actively syncing with CloudKit in this process.

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

Is SwiftData going to be immediately available to use with iOS 16? I ask because I'm working on an app which I'd like to release around the end of this month, and I'm about to implement CoreData for it, but wanted to see when SwiftData would be available. My guess was that SwiftData is for iOS 17 so I should just stick with CoreData for now and switch over later, but just wanted to check to make sure. Thanks!
