Originally created by @shift00 on GitHub (Dec 7, 2017).

I have small issue with my project and CoreStore. I need to have sqlite db on start of my app.
At didFinishLauchingWithOptions AppDelegate function I have this code:
let dataStack: DataStack = DataStack( CoreStoreSchema( modelVersion: "V1", entities: [ Entity<Entity1CSModel>("Entity1"), Entity<Entity2CSModel>("Entity2"), Entity<Entity3Model>("Entity3") ] ) )

CoreStore.defaultStack = dataStack

CoreStore.addStorage( SQLiteStore(fileName: "MyDatabase.sqlite"), completion: { (result) -> Void in print("test") } )

I noticed that completion handler is not called what throws the application when I want to create a new Entity1 entity.

When I want to create/edit my entity I receive this error:

[CoreStore: Fatal Error] BaseDataTransaction.swift:83 create
  ↪︎ Attempted to create an entity of type 'Entity1CSModel', but a destination persistent store containing the entity type could not be found.

addStorage() is an asynchronous operation. Are you sure that your create() call is not being called before the addStorage() completes?

@JohnEstropia I moved block of code when is executed after addStorage() into completion handler and it's working ;) Thanks for tip 👍
