# settings

A dictionary that represents the format as a dictionary using audio setting keys.

## Declaration

```swift
var settings: [String : Any] { get }
```

## Discussion

Discussion The settings dictionary doesn’t support all formats that AudioStreamBasicDescription represents (the underlying implementation), in which case, this property returns nil.
