The trip list, kept in step with the store by @Query.

Overview

Add @Model to a Swift class and it becomes something you can save, fetch and sync. No separate schema file, no managed object subclasses.

In SwiftUI, @Query keeps a view in step with the store, and iCloud sync is a configuration option. Underneath it's built on the same proven storage as Core Data.

@Model

Turn a Swift class into a persistent model. The schema comes from your code.

@Query

Fetch, sort and filter right in a SwiftUI view, and stay in sync with the store.

ModelContainer

Configure storage once at the app level, including iCloud sync and migrations.

ModelContext

Insert, delete and save, with autosave and undo support built in.

Trip.swift

import SwiftData
import SwiftUI

@Model
class Trip {
    var name: String
    var startDate: Date

    init(name: String, startDate: Date) {
        self.name = name
        self.startDate = startDate
    }
}

struct TripList: View {
    @Query(sort: \Trip.startDate) var trips: [Trip]

    var body: some View {
        List(trips) { Text($0.name) }
    }
}
