# userInfo

Optional, app-specific information that you can provide for use when your app performs the Home Screen dynamic mutable quick action.

```
var userInfo: [String : any NSSecureCoding]? { get set }
```

## Discussion

The keys and values in this property’s dictionary must conform to the <doc://com.apple.documentation/documentation/Foundation/NSSecureCoding> protocol, and must be property-list-encodable. If they aren’t, the system raises a runtime exception when initializing the quick action. For information about property-list-encodable data, see [Serializing Property Lists](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Archiving/Articles/serializing.html#//apple_ref/doc/uid/20000952) in [Archives and Serializations Programming Guide](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Archiving/Archiving.html#//apple_ref/doc/uid/10000047i) and see <doc://com.apple.documentation/documentation/Foundation/PropertyListSerialization>.
