Looks like an @Model must be inserted into the context before use in SwiftUI
actor PreviewSampleData {
@MainActor
static var container: ModelContainer = {
let schema = Schema([Trip.self, BucketListItem.self, LivingAccommodation.self])
let configuration = ModelConfiguration(inMemory: true)
let container = try! ModelContainer(for: schema, configurations: [configuration])
let sampleData: [any PersistentModel] = [
Trip.preview, BucketListItem.preview, LivingAccommodation.preview
]
sampleData.forEach {
container.mainContext.insert($0)
}
return container
}()
@MainActor
static var previewTrip: Trip = {
let container = PreviewSampleData.container
let trip = Trip.preview
container.mainContext.insert(trip)
return trip
}()
}
#Preview {
MainActor.assumeIsolated {
List {
TripListItem(trip: PreviewSampleData.previewTrip)
}
.modelContainer(PreviewSampleData.container)
}
}
