From your stack trace, it looks like bothcalls are Firebase related. As such, try upgrading to the latest Firebase version 4.x to see if those go away.
从您的堆栈跟踪来看，这两个调用似乎都与 Firebase 相关。因此，请尝试升级到最新的 Firebase 版本 4.x，看看它们是否会消失。
Please see this questionif you may need some help when doing so.

Update. Actually, it looks like this is a known issuein Firebase v4 iOS SDK :-(
