# invalidateAllPersistableContentKeys(forApp:options:completionHandler:)

Invalidates all of an app’s persistable content keys and creates a secure server playback context (SPC) to verify the outcome of an invalidation request.

## Declaration

```swift
func invalidateAllPersistableContentKeys(forApp appIdentifier: Data, options: [AVContentKeySessionServerPlaybackContextOption : Any]? = nil, completionHandler handler: @escaping @Sendable (Data?, (any Error)?) -> Void)
```

```swift
func invalidateAllPersistableContentKeys(forApp appIdentifier: Data, options: [AVContentKeySessionServerPlaybackContextOption : Any]? = nil) async throws -> Data
```

## Parameters

- `appIdentifier`: An opaque identifier for the app.
- `options`: Additional data necessary to generate the server playback context. Pass nil to indicate no additional options. See doc://com.apple.avfoundation/documentation/AVFoundation/AVContentKeySessionServerPlaybackContextOption for supported options.
- `handler`: The completion handler callback.
