As per your comments on Ashish's response, it seems like you are not saving the managed object context after inserting the records.

Insertion process:

1. Fresh launch app, initialize core data and insert data in DB
2. Call managedObjectContext.save and check if the save operation is successful or got failure.

Then notify the view controller to refresh the weather list using NSNotification on the main thread or some other mechanism as per your suitability.

And then try to fetch weathers from viewContext for UI rendering.
