# enumerateValues(forProperties:using:) Executes a provided block with the fetched values for the item properties. ``` func enumerateValues(forProperties properties: Set?, using block: @escaping (String, Any, UnsafeMutablePointer) -> Void) ``` ## Parameters `properties` A set of keys for the properties to enumerate, or `nil` to enumerate all properties. Takes Media Item Properties and Playlist Properties from [`ITLibMediaItem`](/documentation/iTunesLibrary/ITLibMediaItem). `block` A block object that executes for each property in the properties set. ## Discussion Use this method to get property values in a batch fashion. In some cases, enumerating over a set of property keys can be more efficient than fetching each individual property with [`value(forProperty:)`](/documentation/iTunesLibrary/ITLibMediaEntity/value(forProperty:)). --- Copyright © 2026 Apple Inc.
