SwiftDB

A type-safe, SwiftUI-inspired wrapper around CoreData.

Get Started

Define an

Entity

struct Foo: Entity, Identifiable {
    @Attribute var bar: String = "Untitled"

var id: some Hashable {
    bar
}
}

Define a

Schema

struct MySchema: Schema {
    var entities: Entities {
        Foo.self
    }
}

Create a

ContentView

struct ContentView: View {
    @StateObject var container = PersistentContainer(MySchema())

var body: some View {
    Text("Hello World")
}
}

Create a list view:

struct ListView: View {
    @EnvironmentObject var container: PersistentContainer

@FetchModels<foo>() var models

var body: some View {
    NavigationView {
        List(models) { foo in
            NavigationLink(destination: EditView(foo: foo)) {
                Text(foo.bar)
            }
            .contextMenu {
                Button {
                    container.delete(foo)
                } label: {
                    Text("Delete")
                }
            }
        }
        .navigationBarItems(
            trailing: Button {
                container.create(Foo.self)
            } label: {
                Image(systemName: .plusCircleFill)
                    .imageScale(.large)
            }
        )
        .navigationBarTitle("A List of Foo")
    }
}

struct EditView: View {
    @EnvironmentObject var container: PersistentContainer

    let foo: Foo

    var body: some View {
        VStack {
            Form {
                TextField("Enter a value", text: foo.$bar) {
                    container.save()
                }
            }
        }
        .navigationBarTitle("Edit Foo")
    }
}
}

Add it to our

ContentView

struct ContentView: View {
    @StateObject var container = PersistentContainer(MySchema())

var body: some View {
    ListView()
        .persistentContainer(container)
}
}

That's it.
