# mainAppContext

The app’s top-level context.

## Declaration

```swift
var mainAppContext: CLSContext { get }
```

## Discussion

Discussion Every app has exactly one top-level context that acts as the root node in a hierarchy of contexts that you define. Its identifier is the app’s bundle identifier. You can neither create nor destroy this context.
