In this line:

NSEntityDescription *entity = [NSEntityDescription insertNewObjectForEntityForName:@"History" inManagedObjectContext:context];

The method you're calling returns an instance of NSManagedObject. You are assigning it to a variable of type NSEntityDescription. That's what the message is telling you.

So how to declare the NsEntityDescription – Bosoud Apr 09 '16 at 23:04
You can look it up in the `NSManagedObjectModel`, but this is rarely necessary or useful. What are you trying to do here? It looks like you want to create a new instance of the entity. If so then you're doing everything right *except* using the wrong variable type on that line. The line creates an `NSManagedObject`, which is what it looks like you want. – Tom Harrington Apr 09 '16 at 23:07
