# enumerateValues(forProperties:using:) Executes a provided block with the fetched values for the given item properties. ``` func enumerateValues(forProperties properties: Set, using block: @escaping (String, Any, UnsafeMutablePointer) -> Void) ``` ## Parameters `properties` A set of property keys that you want the values for. `block` A block object that executes for each fetched property value. ## Discussion Use this method to get property values in a batch fashion. Anytime the app accesses more than one property, enumerating over a set of property keys is more efficient than fetching each individual property with [`value(forProperty:)`](/documentation/MediaPlayer/MPMediaEntity/value(forProperty:)). To see which media property keys you can use with this method, refer to [Media entity property keys](/documentation/MediaPlayer/media-entity-property-keys), [General media item property keys](/documentation/MediaPlayer/general-media-item-property-keys), [Playlist property keys](/documentation/MediaPlayer/playlist-property-keys), and [User-defined property keys](/documentation/MediaPlayer/user-defined-property-keys). --- Copyright © 2026 Apple Inc.
