Migrate to SwiftData

4:37 - Creating a ModelContainer in SwiftUI

@main
struct TripsApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        .modelContainer(
            for: [Trip.self, BucketListItem.self, LivingAccommodation.self]
        )
    }
}

4:57 - Object creation in Core Data

@Environment(\.managedObjectContext) private var viewContext

let newTrip = Trip(context: viewContext)
newTrip.name = name
newTrip.destination = destination
newTrip.startDate = startDate
newTrip.endDate = endDate

5:30 - Object creation in SwiftData

@Environment(\.modelContext) private var modelContext

let trip = Trip(
    name: name, 
    destination: destination, 
    startDate: startDate, 
    endDate: endDate
)

modelContext.insert(object: trip)

6:16 - Fetch with Query in SwiftData

@Query(sort: \.startDate, order: .forward)

var trips: [Trip]

7:30 - Setting store path and enabling persistent history tracking in Core Data

let url = URL(fileURLWithPath: "/path/to/Trips.store")

if let description = container.persistentStoreDescriptions.first {
    description.url = url
    description.setOption(true as NSNumber, forKey: NSPersistentHistoryTrackingKey)
}

9:11 - Ensuring Core Data and SwiftData class names are unique

class CDTrip: NSManagedObject {
    // ...
}


@Model final class Trip {
    // ...
}
