iphone – 无法启动模拟应用程序：未知错误

当我尝试在模拟器中执行我的iPhone应用程序时，我收到可怕的错误消息：

Failed to launch simulated application: Unknown error.

我的应用程序有两个目标，但是这两个都出现这个错误。

当发生错误时，模拟的操作系统挂起 – 它显示黑屏，不再响应任何输入。模拟器应用程序本身不挂起 – 所有菜单都处于活动状态。

我尝试运行的所有其他应用程序(大多数是Apple示例)都能正常工作。清理缓存，重新启动和啸叫在月球上没有帮助。从零开始重建项目也没有帮助。我想我必须在较小的步骤中再做一次。

同时，下面还有其他一些事情要尝试吗？

> Xcode |空缓存…
>删除目录/Library/Caches/com.apple.DeveloperTools.###
>完全重建
>重新启动
>更改产品名称(它不包含任何空格)
>创建新项目并从头开始手动配置

请注意，日志中提到了名为VoiceOverTouch的内容。我的应用程序不包含(据我所知)与可访问性相关的任何内容(可能会被一些依赖性引入)。我已经在我的Mac上启用了错误消息中的建议的辅助功能，但没有帮助。我在iPhone模拟器中启用了辅助功能检查器。 VoiceOverTouch消息不再显示在日志中，但未知错误仍然存??在。
