我正在尝试开始使用 Ionic，但是当我使用“ionic emulate ios”进行模拟时，控制台会显示这个 问题：

现在我已经安装了最后一个 Xcode 测试版

Answer 1

您是否检查了标准错误日志中的详细信息？

%project_name%/platforms/ios/cordova/console.log

如果你使用ios9模拟器看到白屏，可能是你遇到了ios9强制使用https的问题。

肮脏的方式只是更新到 xcode 项目配置 plist 以禁用 ATS

platforms/ios/%project_name%/%project_name%-Info.plist 

您可以通过将其添加到配置文件来禁用 Apple Transport Security

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>
<key>NSLocationWhenInUseUsageDescription</key>
<string></string>

Answer 2

使用 Xcode 7 SDK 构建时，我在 Xamarin Studio 中收到类似的错误消息。您是否尝试过在 Xcode 6.3.2 上运行，或者您是否有其他充分理由使用 Xcode 7 beta 运行 Ionic？

根据我的经验，在尝试新工具时最好让您的环境尽可能熟悉，这样会发生不熟悉的事情，因此更容易排除故障。
