If cleaning the project & recompiling it doesn't work then
如果清理项目并重新编译它不起作用那么
- Quit XCode
- Delete the
/Library/Developer/XCode/Derived Datafolder - Start XCode again and compile
- 退出 XCode
- 删除
/Library/Developer/XCode/Derived Data文件夹 - 再次启动 XCode 并编译
Note: this error can happen when using XCode 6.x and XCode 7.x installed (and used) parallel.
注意：当使用并行安装（和使用）的 XCode 6.x 和 XCode 7.x 时，可能会发生此错误。

In my case my submodules were empty which would cause the compiler to crash a simple:
在我的情况下，我的子模块是空的，这会导致编译器崩溃一个简单的：
cd /project/file/path
git submodule init
git submodule update
Solved the issue.

The xctoolchain error can sometimes be caused by Xcode not finding the location of source files in a project that was moved or started by someone else who had a different project location in their own Finder.
xctoolchain 错误有时可能是由于 Xcode 没有在项目中找到源文件的位置，而该项目是由其他人在他们自己的 Finder 中移动或启动的不同项目位置引起的。
If you're working on another project started by someone else such as a GitHub open source project, Xcode can mistake the location of the source files.
如果您正在处理其他人启动的另一个项目，例如 GitHub 开源项目，Xcode 可能会弄错源文件的位置。
Xcode may think ViewController.swift is still in the project folder on the creator's desktop when it's actually on your own desktop. In this case some of your source files may be red because Xcode cannot find them.
Xcode 可能认为 ViewController.swift 仍在创建者桌面上的项目文件夹中，而实际上它在您自己的桌面上。在这种情况下，您的某些源文件可能是红色的，因为 Xcode 找不到它们。
Go to the Xcode Identity Inspector on the right side and in the Identity and Type section you'll see the Location pulldown.
Select a red missing file in the Project Navigator on the left.
Make sure the Identity Inspector pulldown is set to 'Relative To Group'.
Click the folder icon underneath to navigate to the real file location, select your file and click Choose. The Full Path will now reflect the correct location.
Clean and rebuild.
转到右侧的 Xcode Identity Inspector，在 Identity and Type 部分，您将看到 Location 下拉菜单。
在左侧的项目导航器中选择一个红色的缺失文件。
确保 Identity Inspector 下拉菜单设置为“Relative To Group”。
单击下方的文件夹图标导航到实际文件位置，选择您的文件并单击选择。完整路径现在将反映正确的位置。
清洁和重建。
