# isRunning

A Boolean that indicates whether the target application represented by the receiver is running.

## Declaration

```swift
var isRunning: Bool { get }
```

## Discussion

Discussion true if the application is running, false otherwise. This may be true for instances initialized with a bundle identifier or URL because SBApplication launches the application only when it’s necessary to send it an event.
