Question

我曾经有一个功能完善的iOS / swift应用程序。尝试并且无法通过Carthage和CocoaPods安装FacebookLogin SDK后，我的项目就不再编译了。我试图回到我的代码的早期版本，但xcode一直在寻找pod文件的引用等。

在尝试安装Facebook SDK之前，我甚至已经完成了创建新项目的时间，同时复制了之前存在的所有文件。

现在，我没有对Podfiles的任何引用，但现在我有一个C错误：

clang: error: linker command failed with exit code 1 (use -v to see invocation)

我很确定在尝试编译我所拥有的唯一非swift文件时会调用此错误：我使用的Objective-C库：SWRevealViewController，我用于菜单。这之前用于编译好。

您是否尝试使用模拟器以外的设备，某些SDK只能在设备上运行。
