How do I use SwiftData?

To use SwiftData, 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 helps in setting up the schema for your data.

import SwiftData

@Model
class Trip {
    var destination: String
    var date: Date
    // Add other properties as needed
}

Set Up Model Container: Use the ModelContainer to manage your models. You can configure it to use different data stores, including custom ones.
```
let container = ModelContainer([Trip.self])
```
Use Queries: Populate your views by querying the model container. This can be done using the @Query property wrapper.
```
@Query var trips: [Trip]
```
Custom Data Stores: If you need to use a custom data store, you can configure it by implementing the DataStore protocol and passing it to the model container.
```
let customStore = CustomDataStore()
let container = ModelContainer([Trip.self], store: customStore)
```
Track Changes: SwiftData provides a history API to track changes in your data, which is useful for syncing with remote servers or handling app extensions.
```
let history = try container.history()
```
