我最近更新到 Xcode 8.3.2 并且 push 停止工作;虽然我没有更改任何东西，只是将 swift 版本升级到当前版本

在我的Firebase控制台中，当我发送到所有iOS swift设备(我只注册了一个(时，统计信息显示0(屏幕截图 http://joxi.ru/Y2LBBaVH39alr6(

我得到的推送令牌是

不确定这是否有帮助，但为了避免 iOS 10+(Swift 3.1.1 和 XCode 8.3.2(的弃用代码，这是一个示例 AppDelegate.swift 文件，用于使推送通知正常工作。(注： 除了启用推送通知之外，还必须在 XCode 项目的">功能"菜单下的">后台模式"中启用"远程通知"。

        //create the notificationCenter
