在Xcode 6.3中将测试目标添加到现有项目中

Question

注意：这个问题是相关的，但那里给出的答案并没有解决我的问题：XC Testing Framework iOS(XCode 6.1) Test session exited(80) without checking in

我有现有的iOS代码，我想用Xcode 6.3开始编写XCTest案例。我通过单击Test Navigator中的+来创建测试目标。为我创建了一个测试目标，包括一个带有单元测试的文件测试。

测试在测试导航器中显示为灰色（我无法单击cmd + T）。

问题1 ：如何启用测试？

编辑：此屏幕截图中描述了答案：https://www.evernote.com/shard/s4/sh/6a5ca990-d723-46ee-bf77-2cf0ff4e70b2/1a62c472fbbeeffa595fcecd4a9fbbf7，我在此处找到：Adding Unit Tests to an already existing project?

在我的项目设置中，我的生产目标（旧版）有以下设置： 以及我的测试目标的以下设置（自动生成）：

如果我通过单击Test Navigator中的Play按钮手动运行我的测试，则会收到以下大量错误消息。

问题2 ：我还需要检查/更改哪些设置才能运行测试？

编辑将arm64添加到生产目标有效体系结构中解决了此特定错误。添加会有危险吗？
