Why NSFetchRequest always fetched the recently create entity even the entity is out of fetch offset?-CodePudding

I have a data model with just one record, a NSFetchResult instance that was set up with fetchOffset at 10.

Assets: NSManagedObject

let fetchRequest = Assets.fetchRequest()

After saving a new data model I run the request I got 2 entities from the fetch result.

let fetchResult = try context.fetch(fetchRequest) as? [Assets]

I scheduled a dispatch queue to run exactly the same fetch request after 10s then the result is empty as I expected.

let fetchResult = try context.fetch(fetchRequest) as? [Assets]

Can you give me any advice?

How can I should do to make the fetch result work as expected?

I suspect you have unsaved changes in your context in the first call. Try setting:

fetchRequest.includesPendingChanges = false
