iOS 模拟器错误 DTAssetProviderService 无法启动并重新启动无济于事
iOS Simimulator error DTAssetProviderService could not start and restart not helping
我最近将我的 MBP 升级到 El Capitan 和 XCode 7.3.1，但是当我尝试 运行 我在模拟器中的项目时，我收到 "DTAssetProviderService could not start" 错误。我已经尝试清理，重新启动这两个工具，然后重新启动我的机器，但问题仍然存在。在 /var/log/system.log 中，这里是当时的相关日志：

此 引用了几个与重新启动和清理不同内容相关的修复程序，但 none 对我有用。还有其他想法吗？
事实证明这是我的 IT 部门安装 WebSense 的问题。将库注入其他进程（例如 Simulator）是众所周知的。删除后，它又开始工作了。
