Question

我是iOS应用开发的初学者。我目前正在开发一个需要从Parse更改为Firebase的项目。

我安装了可可豆荚和＆＃34; firebase/core＆＃34; pod作为firebase网站指示。
在appdelegate.h中导入firebase.h
在＆＃39; [FIRApp configure];＆＃39;

didfinishlaunchingwithoptions

添加＆＃39; googleservice-info.plist＆＃39;在项目中。

执行这些步骤后，我运行了构建，但失败并出现以下错误（Screen Shot）

我知道这与我项目中的解析代码有关，但我在Parse或Firebase中没有太多的知识。

请帮我解决此错误，并指导我如何成功从Parse迁移到Firebase。

如果您使用的是Parse SDK，只需从项目中删除ParseFacebookUtils.framework库，或从podfile删除

pod 'Parse'
pod 'ParseFacebookUtilsV4'

安装Firebase pod后链接器错误
