# MPMediaItemPropertyPodcastPersistentID

The persistent identifier for an audio podcast.

## Declaration

```swift
let MPMediaItemPropertyPodcastPersistentID: String
```

## Discussion

Discussion This value is an NSNumber object that contains a uint64_t (unsigned long long). The value of the MPMediaItemPropertyPodcastPersistentID identifier persists across application launches and across syncs that do not change the sync status of the media item. The value is not guaranteed to persist across a sync/unsync/sync cycle. Can be used to build a media property predicate as described in MPMediaPropertyPredicate.
