ios - 运行应用程序时 xCode 崩溃

Question

每次我尝试在 Xcode 中运行 iOS 应用程序时，它都会崩溃。我已经尝试重新启动我的机器，在物理硬件和模拟器上运行应用程序，并从 xcodeproj 包中清除 xcuserdata 文件夹。对于这些尝试中的每一个，当我按下运行按钮或键入“cmd + R”时，Xcode 立即崩溃。

我在下面包含了崩溃报告以获取更多信息。我正在运行 OSX 10.11 和 Xcode 版本 7.0.1 (7A1001)。有没有其他人有幸解决这个问题？

我看到了同样的行为。我找到了 this thread在 Apple Developer 网站上解释了该怎么做:关闭 Xcode 项目中所有标题为空的选项卡。为我解决了这个问题，这就解释了为什么恢复解决了这个问题。不知何故，项目文件已损坏。
