How to create or access a SwiftData Persistent Container in Swift

To access or create a persistent container in SwiftData, use the code below.

Please remember to replace _SwiftDataModelName_ with the name of the SwiftData model that you wish that container to access. For multiple models, use a comma-separated convention i.e. [ModelA.self, ModelB.self, ModelC.self].

We recommend that you place it within a Singleton called DataCoordinator that acts as a MainActor.

We recommend placing this functionality within a Singleton that acts as a MainActor. If you do not use a MainActor, you will have to use Async/Await patterns.

For more information on the Persistent Container and what you can do with it, check out the WWDC videos linked below.
