Property 'persistentContainer' not found on object of type 'AppDelegate *'

In a swift project, i’m using some objective c class files. from these files i need to call AppDelegate.swift file to access to pesistentContainer. but Xcode give me this error. How can I fix it?

@rufy Thanks very much for your question!

It seems that you haven’t declared a property called “persistentContainer” in your AppDelegate class.

I hope this helps!

All the best!

@syedfa I’m sorry but it’s not correct. when you create a project that use Core Data, that variable is automatically created. there is one note: it’s lazy.

there are anyone can give an solution of this problem?
