Core Data Child Context

Question

I have 2 questions regarding context creation.

When i access main context via singleton:

let appDelegate = UIApplication.shared.delegate as! AppDelegate
let managedContext = appDelegate.managedObjectContext

Is that the SAME context everytime?

And if i then create a child context like this:

let bgContext = NSManagedObjectContext(concurrencyType: .privateQueueConcurrencyType)

With Parent as the about main context, is that the SAME child context or is it generating a completely new child context.

Thanks!

Answer 1

Yeah, as long as it's a stored property, appDelegate.managedObjectContext is the same object every time.

And to your second question, that's a new child context. You can go from here to read more from Apple's documentation.
