How do I use swiftdata

To use SwiftData in your app, you can follow these steps:

Import the Framework: Start by importing the SwiftData framework into your project.
Define Your Models: Use the @Model macro to define your data models. This macro simplifies the process of defining your schema. For example:
```
import SwiftData

@Model
class Trip {
    var destination: String
    var date: Date
    // Add other properties as needed
}
```
Configure the Model Container: Use the modelContainer modifier on your WindowGroup to tell the view hierarchy about your model. This allows your views to fetch and display data from the model container.
```
@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
                .modelContainer(for: Trip.self)
        }
    }
}
```

Query Data: Use SwiftData's query capabilities to fetch data from the model container. For example, you can fetch all Trip models like this:

struct ContentView: View {
    @Query var trips: [Trip]

    var body: some View {
        List(trips) { trip in
            Text(trip.destination)
        }
    }
}

Custom Data Stores: If you need to use a custom backend for your data, you can configure a custom data store. This allows you to use SwiftData's API with different storage backends like SQLite, a remote web service, or JSON files. For more details, you can refer to the session Create a custom data store with SwiftData.
Track Changes: SwiftData also provides a history API to track changes in your data store, which is useful for features like syncing with a remote server. For more information, you can watch the session Track model changes with SwiftData history.

For a detailed walkthrough and examples, you can refer to the session What’s new in SwiftData.
