# delete(with:completion:) Deletes the interactions with the specified group identifier. ``` class func delete(with groupIdentifier: String, completion: (@Sendable ((any Error)?) -> Void)? = nil) ``` ## Parameters `groupIdentifier` The group identifier string of the interactions that you want to delete. This string corresponds to the value stored in the [`groupIdentifier`](/documentation/Intents/INInteraction/groupIdentifier) property of the interaction objects. `completion` A block to execute with the results. Provide a block if you want to know whether the deletion action succeeded. The block has no return value and takes the following parameter. - error: An error object indicating a problem occurred. On success, this parameter is `nil`. If there was an error, this parameter contains an error object describing what happened. ## Discussion Call this method to delete a group of donated Siri interactions. Typically, you delete interactions when they are no longer relevant. For example, if you have associated an interaction identifier with a playlist, you can delete all the interactions about the list if the user deletes it. If you provide a block in the `completion` parameter, the system executes your block asynchronously with the results. --- Copyright © 2026 Apple Inc.
