How do I batch delete data in SwiftData?

To batch delete data in SwiftData, you can utilize the `NSBatchDeleteRequest` class, which is part of the Core Data framework that SwiftData is built upon. First, create a fetch request for the objects you want to delete. Then, use `NSBatchDeleteRequest` with the fetch request to delete the objects in a batch operation. This approach is more efficient than fetching and deleting objects individually, as it reduces memory usage and improves performance. Additionally, consider using `NSPersistentContainer` to manage your Core Data stack, which simplifies the process of setting up and interacting with your data store.
