Xcode 8 Beta - Convert to Current Swift Syntax Failed: Could not find test host
提问by thejuki
I am receiving an error message when I try to use Xcode 8's Convert Wizard. After trying rebooting, downloading fresh code, and deleting my DerivedData files I cannot escape this error:
当我尝试使用 Xcode 8 的转换向导时收到一条错误消息。尝试重新启动、下载新代码并删除我的 DerivedData 文件后，我无法逃避此错误：
Convert to Current Swift Syntax Failed: Could not find test host
转换为当前 Swift 语法失败：找不到测试主机
I have tried both options which are: Swift 2.3 and Swift 3. After I select a version I instantly get that error.
我已经尝试了以下两个选项：Swift 2.3 和 Swift 3。在我选择一个版本后，我立即收到该错误。
Here is a screenshot of the error:

This worked for me:
这对我有用：
- Select the Xcode project in the lefthand browser.
- Click on your test target in the Project's
Generaltab. - Disclose "Testing". In my project the "Host Application" pulldown button was blank. Select your appropriate host application.
- Try building your test target now. If that succeeds then converting syntax should as well.
- 在左侧浏览器中选择 Xcode 项目。
- 单击项目
General选项卡中的测试目标。 - 披露“测试”。在我的项目中，“主机应用程序”下拉按钮是空白的。选择合适的主机应用程序。
- 立即尝试构建您的测试目标。如果成功，那么转换语法也应该如此。
I had this problem after installing the Xcode 8 beta so I assume this is related.
安装 Xcode 8 beta 后我遇到了这个问题，所以我认为这是相关的。

It cost me a bit of time to find the "Host Application" pulldownmentioned in the otherwise very helpful answer by iluvcapra.
我花了一些时间才找到iluvcapra 在其他非常有用的答案中提到的“主机应用程序”下拉菜单。
So this is what he meant:
所以这就是他的意思：
This is where you find the pulldown menu. Select your main target.
您可以在此处找到下拉菜单。选择您的主要目标。

I find easy fix for this, just edit your Scheme and disable tests.
我找到了简单的解决方法，只需编辑您的方案并禁用测试即可。
And run conversion again.
并再次运行转换。

Alternatively, use text editor to remove the following two items from your MyAppSwift.xcodeproj/project.pbxprojfile, search for TEST_HOST
或者，使用文本编辑器从MyAppSwift.xcodeproj/project.pbxproj文件中删除以下两项，搜索TEST_HOST
Now, re-open your project and run the convert wizard again.
现在，重新打开您的项目并再次运行转换向导。

In my case I deleted my tests target, then re-added it using the + below targets and selecting "iOs Unit Testing Bundle"
就我而言，我删除了我的测试目标，然后使用下面的 + 目标并选择“iOs 单元测试包”重新添加它
For some reason this got a compile error, so I changed the "Per-configuration Intermediate Build Files Path: for my test target to $(PROJECT_TEMP_DIR)/$(CONFIGURATION) for both debug and release. This allowed the compile to work.
由于某种原因，这出现了编译错误，所以我将“每配置中间构建文件路径：对于我的测试目标更改为 $(PROJECT_TEMP_DIR)/$(CONFIGURATION) 以进行调试和发布。这允许编译工作。

Fix this in 3 steps:
分三步解决这个问题：
- First delete your test target
- The select Edit -> Convert -> To current Swift syntax... and perform the conversion
- Then add a new test target
- 首先删除您的测试目标
- 选择 Edit -> Convert -> To current Swift syntax... 并执行转换
- 然后添加一个新的测试目标
