This package is under development and is being currently rewritten to fully leverage Swift 5.9.
A modern, type-safe database abstraction layer. SwiftDB aims to be an opinionated DBAL for relational and document-oriented databases.
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 @QueryModels<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() .databaseContainer(container) } }That's it.
