class let launchIsDefaultUserInfoKey: String
```

## Discussion

The value for this key is an <doc://com.apple.documentation/documentation/Foundation/NSNumber> containing a Boolean value. The value is <doc://com.apple.documentation/documentation/Swift/false> if the app was launched to open or print a file, to perform a Service action, if the app had saved state that will be restored, or if the app launch was in some other sense not a default launch. Otherwise its value will be <doc://com.apple.documentation/documentation/Swift/true>.
