swift - 如何为 UI 测试包启用网络流量？ (XCTest、XCode - DNSServiceCreateConnection 失败)

Question

当我使用来自集成测试(单元测试包)的 http/https 通信时，它工作正常。但是，当我在 UI 测试包中使用相同的代码时，出现以下错误跟踪:

我在 Apple 发起了技术支持事件，他们回答说这是他们方面的错误。请让我在他们的错误报告系统中打开一张票。门票自 2016 年 12 月 20 日起开放。希望他们能尽快解决。

与此同时，我找到了解决方法。我把:

#if DEBUG  
// cleaning server configuration
#endif

在生产代码中，我正在那里进行必要的清理操作。如果在 Debug模式下构建，此代码将在生产代码中翻译。
