Easily spin up a CoreData stack and create type safe interfaces for retrieving managed objects

Usage

CoreDataManager

After creating an xcdatamodel file and NSManagedObject subclasses, here's how to use the CoreDataManager and CoreDataInterface classes.

the CoreDataManager is responsible for storing the models to disk, adding persistent store coordinators with the given type, and providing managed object contexts to perform work with.

You can extend the CoreDataManager to create any static shared instances. Example:

extension CoreDataManager {
  static let shared = CoreDataManager(modelName: "Your-Model-Name", storeType: .sqlite, bundles: [.mainBundle()])
}

to which the two context types can be accessed by calling:

let mainContext = CoreDataManager.shared.mainContext 

or

let privateContext = CoreDataManager.shared.privateContext

CoreDataInterface

A CoreDataInterface gets created with a context and a generic NSManagedObject type.

Given the custom subclass Place:

let interface = CoreDataInterface<Place>(context: CoreDataManager.shared.mainContext)

to which any of the CoreDataInterfaceType functions can be called on it.
