How to get a ParseInstallation in Swift

Client SDKs iOS SDK 📱⌚️💻
1

Docs here say

// Swift
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let installation = PFInstallation.currentInstallation()
    installation.setDeviceTokenFromData(deviceToken)
    installation.saveInBackground()
}

But PFInstallation is not found
I can successfully call
ParseSwift.initialize
but no idea how to get an Installation instance

Thanks
