每次我尝试打开PROJECT信息时Xcode都会崩溃

Question

我最近遇到了一个奇怪的问题。当我尝试打开每个项目的项目信息时，我的Xcode每次都会崩溃。

通过项目信息我指的是：

然而，其他一切似乎都很完美，包括构建档案，在模拟器和真实设备上运行构建。

另外，我尝试了很多方法，例如删除/ DerivedData和/ xuserdata，但没有一种方法对我们有所帮助。

以下是Xcode问题报告的一部分，如果您需要深入了解它：

Answer 1

尝试升级项目，方法是转到“项目设置”并单击“文件检查器”（即IDE窗口右侧显示的面板或选项卡）。

出现的其中一个弹出菜单应为＆＃34; Project Format＆＃34;。

选择＆＃34; Xcode 6.3兼容＆＃34;看看是否能让你的生活更美好。
