I'm using UserDefaults to save the "keyValueVersionStore" once I clicked the complete button my project is breaking with
Attempt to set a non-property-list object 1.3.0 as an NSUserDefaults/CFPreferences value for key de.tiigi.whatsnewkit.1.3.0

Here is how I set up whatsNewViewController

// Local KeyValueStore
    let keyValueVersionStore = KeyValueWhatsNewVersionStore(
      keyValueable: UserDefaults.standard
    )
    
    let whatsNewController = WhatsNewViewController(whatsNew: whatsNewVersion4, configuration: configuration, versionStore: keyValueVersionStore)
  
    if let controller = whatsNewController {
      // Present it as WhatsNewViewController is available
      // after init with WhatsNewVersionStore
     self.present(controller, animated: true)
    } else {
      // WhatsNewViewController is `nil` this Version has already been presented
    }
