# state

A dictionary of state information to be evaluated by the system’s rules.

## Declaration

```swift
var state: NSMutableDictionary { get }
```

## Discussion

Discussion This dictionary is mutable—some rules might alter the system’s state when executed. If you change this dictionary’s contents outside of a rule action, you must reset and reevaluate the system.
