[!] `<PBXSourcesBuildPhase UUID=`BC2BAE431A89F1450060D863`>` attempted to initialize an object with an unknown UUID. `38F3FD552A2F25DF00AEAAC4` for attribute: `files`. This can be the result of a merge and the unknown UUID is being discarded.

这个错误通常是由于合并代码时导致的,可能会导致未知的UUID被丢弃。解决方法如下:

从CocoaPods中解除你的项目。删除Xcode项目中所有CocoaPods的痕迹。

$ pod deintegrate

再次安装Pod。

$ pod install
