NOTE: This is a Q&A Question that is being answered by the author.

注意:这是作者正在回答的问题。

This is an issue of having Xcode 7 already installed, and the latest snapshot being unable to run properly.

这是已经安装了Xcode 7的问题，最新的快照无法正常运行。

Execute the following steps

执行以下步骤

Completely open Xcode 8 and install additional components as prompted
完全打开Xcode 8并按提示安装其他组件
Make sure you've downloaded DEVELOPMENT-SNAPSHOT-06-20-A here
确保你已经在这里下载了开发- snapshot -06-20- a
Run the following command

运行以下命令
```
sudo xcode-select -s /Applications/Xcode-beta.app/
```
or go to Xcode preferences, then to the Locations tab and setting the "Command Line Tools" popup to Xcode 8.0.

或者转到Xcode preferences，然后转到Locations选项卡，并将“命令行工具”弹出到Xcode 8.0。

This will tell your system to use the Xcode-beta tools which support latest Swift

这将告诉您的系统使用支持最新Swift的Xcode-beta工具。

Note: In above example, Xcode-beta is expected to be the name of your beta. If you change the names to something like Xcode-beta2, replace above. In occasional situations, users have had to do -s /Applications/Xcode-beta.app/Contents/Developer

注意:在上面的示例中，Xcode-beta应该是beta的名称。如果将名称更改为Xcode-beta2，请在上面进行替换。在偶然的情况下，用户不得不做-s /应用程序/Xcode-beta.app/内容/开发人员
Return to your project and Verify that your project specifies Vapor 0.13, it will look like this:

返回到您的项目并验证您的项目指定了蒸气0.13，它将如下所示:
```
.Package(url: "https://github.com/qutheory/vapor.git", majorVersion: 0, minor: 13),
```
Build your Xcode project

建立你的Xcode项目
```
swift package generate-xcodeproj
```
Completely quit Xcode 7 if it is running

如果Xcode 7正在运行，请完全退出
Open Xcode project with open *.xcodeproj

使用Open *.xcodeproj打开Xcode项目
Verify the project was opened with Xcode 8

验证项目是用Xcode 8打开的
Select toolchain Xcode > Toolchains > DEVELOPMENT-SNAPSHOT-06-20-A

选择工具链Xcode >工具链>开发- snapshot -06-20- a。
