ios - 3D Touch 快速动作总是使用同一个控制器？

Question

对 Swift 来说相对较新，如果这很明显，我很抱歉。尝试创建快速操作链接以打开不同的选项卡视图：

快速操作链接

每当我尝试使用此代码打开操作时，尽管它总是转到第一个“特色”快速操作？

func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {

    if shortcutItem.type == "matthewfrankland.RonaldYule.contacts"{
        let sb = UIStoryboard(name: "Main", bundle: nil)
        let vc = sb.instantiateViewController(withIdentifier: "contacts") as! Contact
        window?.rootViewController?.addChildViewController(vc)
    }

    if shortcutItem.type == "matthewfrankland.RonaldYule.allvideos" {
        let sb = UIStoryboard(name: "Main", bundle: nil)
        let vc = sb.instantiateViewController(withIdentifier: "allVideos") as! AllVideos
        window?.rootViewController?.addChildViewController(vc)
    }

    if shortcutItem.type == "matthewfrankland.RonaldYule.featured"{
        let sb = UIStoryboard(name: "Main", bundle: nil)
        let vc = sb.instantiateViewController(withIdentifier: "featured") as! Featured
        window?.rootViewController?.addChildViewController(vc)
    }
}
