how to complete CloudKit save on app quit

Question

I have an app which saves some state data with CloudKit. The save and restore work properly however, I want to save the last state when the user selects the Quit command. I issue the call;

func applicationWillTerminate(_ aNotification: Notification) {

    cmsHW.saveState()

}

but the CloudKit save called in saveState() never completes. Is there a way to wait for it to finish before the app exits?

我自己的解决方法是；

1-在applicationShouldTerminate中调用saveState函数

      func applicationShouldTerminate(_ sender : NSApplication) -> NSApplication.TerminateReply
      {

          cmsHW.saveState(sender:self)
          return  NSApplication.TerminateReply.terminateLater
      }

和 2-商店操作完成后；

        NSApp.reply(toApplicationShouldTerminate: true)

完成终止。
