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 for your application:
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.
