我尝试了两个选项:Swift 2.3和Swift3.选择一个版本后，我立即收到该错误.

推荐答案

这对我有用:

1. 在左侧浏览器中选择Xcode项目.
2. 在项目"的"General"选项卡中单击测试目标.
3. 披露测试".在我的项目中，主机应用程序"下拉按钮为空白.选择合适的主机应用程序.
4. 尝试立即建立测试目标.如果成功的话，那么转换语法也应该如此.

1. Select the Xcode project in the lefthand browser.
2. Click on your test target in the Project's General tab.
3. Disclose "Testing". In my project the "Host Application" pulldown button was blank. Select your appropriate host application.
4. Try building your test target now. If that succeeds then converting syntax should as well.

在安装Xcode 8 beta之后，我遇到了这个问题，所以我认为这是相关的.

I had this problem after installing the Xcode 8 beta so I assume this is related.
