我在模拟器上安装应用程序时遇到问题。我创建了一个新项目（完全不做任何修改）并点击构建，它构建成功，然后打开模拟器。此时我收到一条错误消息，提示“此时无法安装此应用程序”。
我正在运行 macOS Catalina 10.15 Beta。直接从 Appstore 安装了 Xcode 11.1 并创建了一个不会出现该错误的新项目。我安装了 Xcode 11.2 Beta，也收到了同样的错误。我已经多次重新启动计算机，并且我也经常正常关闭 Xcode 和模拟器，并在没有运气的情况下强制关闭它们。我不确定还能尝试什么。如果有任何区别，这是在带有 Touchbar 的 2017 MacBook Pro 上。
以下是错误详细信息：
