这是我的Xcode项目Podfile文件和Pod显示为：

我也是现在使用的Xcode 8.2测试版

编辑：

在我还包括我的解决方案为我做了什么，因为大多数其他的人的并没有致力于解决这个问题的结束。随意看看解决方案。

Answer 1

阅读上述方案后，他们没有给我工作过，所以我开始试验自己，看看是否有解决这个问题的任何其他解决方案。

下面是他引导我解决这个问题的步骤：重新创建项目

1. 。 （我复制了我需要的文件，并省去了我不需要的文件，所以我只复制了Main.storyboard和Assets文件）

2. 正确安装Pod。 （我再次使用了我正在使用的教程，并确保我安装的是与他安装的相同的确切窗格。项目编译时没有任何错误。）

3. 编码ViewController.swift和Appdelegate文件。 （我再次观看了教程，并仔细地重写了他在教程中编写的代码）

4. 构建项目并理解错误。 （我使用正确的方案设置构建了项目，然后我经历了控制台中显示的任何错误，并纠正了它们。）我遇到的所有错误都在本教程中提供了解决方案。

5. 该项目已成功创建，没有任何错误！

Answer 2

您应该更改scheme name。删除旧的scheme并添加新的！

您可以将Product>Scheme>Manage Schemes并按下自动创建为你的目标计划"Autocreate Schemes Now"

参考：this so post

Answer 3

打开构建设置 转到框架搜索路径

此继承&项目目录将导致Pod自动检测，并且它不会为您造成更多问题。试着这样做，它会自动检测到吊舱。可能会有帮助

Answer 4

1. 在您的podfile中，注意`to'之间的区别。

2. 一旦得到解决，您可以：

   一个。清洁项目（产品 - >清洁）

   b。关闭XCode

   c。运行pod install

   d。打开yourProjectName.xcworkspace
