# isRunning

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

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

## Discussion

<doc://com.apple.documentation/documentation/Swift/true> if the application
is running, <doc://com.apple.documentation/documentation/Swift/false>
otherwise.

This may be <doc://com.apple.documentation/documentation/Swift/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.
