# bundleIdentifier

The bundle identifier of the app in use.

## Declaration

```swift
var bundleIdentifier: String? { get }
```

## Discussion

Discussion The framework sets a value for this property only if the bundle identifier corresponds to an Apple app. Otherwise, you can correlate the app by using the reportApplicationIdentifier property.
