这就是我的 Xcode Project Podfile 文档和 Pods 显示的内容：
我目前也在使用 Xcode 8.2 beta

最后，我将解决问题的方法包括在内，因为大多数其他方法都没有用。随意看看解决方案。
您应该更改 scheme name。删除旧的 scheme 并添加新的！
您可以通过转到 Product > Scheme > Manage Schemes 并按 "Autocreate Schemes Now"
为您的目标自动创建方案
参考：this so post
打开构建设置
转到框架搜索路径
这个继承的 & 项目目录会引起 Pods 的自动检测，它不会再给您带来问题。尝试这样做它会自动检测 pod。可能这可以帮助
在您的播客文件中，请注意“到”之间的区别。
更正此问题后，您可以：
一个。清理项目（产品 -> 清理）
b。关闭 XCode
c。 运行pod install
d.打开yourProjectName.xcworkspace
看完上面的解决方案后，none 对我有用，所以我开始自己试验，看看是否有其他解决方案可以解决这个问题。
以下是引导我解决此问题的步骤：
正在重新创建项目。 （我复制了我需要的文件，省略了我不需要的，所以我只复制了Main.storyboard和Assets文件）
正确安装 Pods。 （我再次阅读了我正在使用的教程，并确保我安装的与他安装的完全相同 pods。项目构建没有任何错误。）
编码 ViewController.swift 和 Appdelegate 文件。 （又看了一遍教程，把教程里他写的代码小心翼翼的重写了一遍）
构建项目并了解错误。 （我使用正确的方案设置构建了项目，然后我检查了控制台中显示的任何错误，并更正了它们。）我遇到的所有错误，在教程中都有解决方案。
至此项目创建成功，无任何错误！
