# ubiquitousItemIsUploadedKey

The key for a Boolean value that indicates whether the system uploads the item’s data to iCloud storage.

```
static let ubiquitousItemIsUploadedKey: URLResourceKey
```

## Discussion

The system returns the read-only value as a Boolean [`NSNumber`](/documentation/Foundation/NSNumber). The value is `true` if the system uploads this item to iCloud; otherwise, `false`.

> Note:
> When waiting for an upload to complete, don’t poll this key from within a block that you pass to ``doc://com.apple.foundation/documentation/Foundation/NSFileCoordinator/coordinate(readingItemAt:options:error:byAccessor:)`` because the system can’t perform, the coordinated read necessary to obtain this value until that block completes and returns. Instead, use ``doc://com.apple.foundation/documentation/Foundation/NSMetadataQuery`` or an ``doc://com.apple.foundation/documentation/Foundation/NSFilePresenter`` delegate to asynchronously notify your app when the status changes.
