# applicationVersion

The version information to display in the About panel.

## Declaration

```swift
static let applicationVersion: NSApplication.AboutPanelOptionKey
```

## Discussion

Discussion The value of this key is an NSString object with the app version (“Version 1.0”). If not specified, AppKit obtains the version string from the CFBundleShortVersionString key in the app’s Info.plist file. If neither is available, AppKit uses the build version, printed as Version x.x.
