I have created multiple instances of an NSManagedObject entity(for example Car: NSManagedObject) in the default NSManagedObjectContext using MagicalRecord.
I didn't save the context. Is there a way to execute a fetch request and obtain the data that is already in persistent state and the data not yet committed that was added in default context ?
Yes, it is fetched. Please check Apple docs at https://developer.apple.com/reference/coredata/nsmanagedobjectcontext:
An object that meets the criteria specified by request (it is an instance of the entity specified by the request, and it matches the request’s predicate if there is one) and that has been inserted into a context but which is not yet saved to a persistent store, is retrieved if the fetch request is executed on that context.
