# userInfo()

Returns a mutable dictionary for storing arbitrary information.

## Declaration

```swift
func userInfo() -> NSMutableDictionary!
```

## Return Value

Return Value A mutable dictionary.

## Discussion

Discussion The userInfo dictionary is shared—there is one per Quartz Composer context. In fact, it is the same dictionary as the one available for the plug-in execution context for instances of the QCPlugIn class. When you add information to the dictionary, make sure that you use unique keys, such as “com.myCompany.foo”.
