# propertyList

An object that contains data to associate with the command.

```
var propertyList: Any? { get }
```

## Discussion

Use [`propertyList`](/documentation/UIKit/UICommand/propertyList) to associate a small amount of data to the command.

        In Objective-C, the property list should contain only         <doc://com.apple.documentation/documentation/Foundation/NSArray>        ,         <doc://com.apple.documentation/documentation/Foundation/NSDictionary>        ,         <doc://com.apple.documentation/documentation/Foundation/NSString>        ,         <doc://com.apple.documentation/documentation/Foundation/NSNumber>        ,         <doc://com.apple.documentation/documentation/Foundation/NSDate>        , and         <doc://com.apple.documentation/documentation/Foundation/NSData>         objects.
