# enumerateValues(forProperties:using:)

Executes a provided block with the fetched values for the given item properties.

## Declaration

```swift
func enumerateValues(forProperties properties: Set<String>, using block: @escaping (String, Any, UnsafeMutablePointer<ObjCBool>) -> 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

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:). To see which media property keys you can use with this method, refer to Media entity property keys, General media item property keys, Playlist property keys, and User-defined property keys.
