Firebase在IOS上的第一次调用非常慢

Question

第一次调用 firebase 非常慢 > 10 秒，并且发生了一些网络错误。我分叉了 repo 以重现该问题：https://github.com/frankpolkm/ionic-conference-app

它只是将 firebase 添加到了driftyco/ionic-conference-app 演示应用中。请查看https://github.com/frankpolkm/ionic-conference-app/blob/master/app/app.ts中的代码更改

这是控制台日志。添加firebase之前没有网络错误。

请让我知道我做错了什么。

谢谢， 弗兰克
