iOS未定义的体系结构符号x86_64 Xcode

Question

我在我的应用中安装了一些第三方框架。每件事都很好，突然有一天我开始出现以下错误。请注意，只有当我尝试在iOS模拟器上运行我的应用程序时才会出现这些链接器错误。

任何帮助都将受到高度赞赏。我可以调试，构建和存档我的项目，如果我在实际设备上但不在模拟器上。我已经通过cocapods添加了所有这些框架，我正在使用Xcode 7.3。

我遇到了同样的错误。如下所示

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_AFJSONRequestSerializer", referenced from:
      objc-class-ref in CuebiqSDK(BADispatcherHelper.o)
  "_OBJC_CLASS_$_AFURLSessionManager", referenced from:

我还没有在错误中提到的项目中添加 AFURLSessionManager 相关类。所以，我添加了所有AFNetworking类解决了这个问题。确保将它们添加到项目目标并显示在Build phases-＆gt; Compile Sources
