AppDelegate.swiftでURLから起動の時

    func application( _: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        for item in options.userActivities {
            if item.activityType == NSUserActivityTypeBrowsingWeb {
                // URLから起動の時はここにくる
            }
        }

        return UISceneConfiguration(
            name: "Default Configuration",
            sessionRole: connectingSceneSession.role
        )
    }
