根据Apple对我说“这个问题解决了Xcode 7.1 Beta版本。我们建议下载Xcode 7.1 Beta版本。我试过后解决了这个问题。
答案 1 :(得分：0)
尝试从PBXBuildFile删除project.pbxproj部分。这应该允许您再次正常打开Xcode。然后，您必须重新配置构建设置（编译源，复制捆绑资源等）。
答案 2 :(得分：0)
我有同样的问题。仍然不知道技术原因。
在我的项目中，我有一个Today-Extension，崩溃原因是Storyboard文件。 自从我删除了Storyboard文件后，Xcode 7就不再崩溃了。
我想我必须创建一个新的Storyboard并重新创建Storyboard文件。
我请客人用旧的Xcode（Xcode 6）删除你的故事板，然后通过尝试和错误看看Xcode 7是如何反应的。
答案 3 :(得分：0)
我在使用XCode 7中的故事板打开项目时遇到了同样的问题。如果您在6.4或7.1 Beta中打开项目并将Compile Sources构建阶段中的任何IB文件移动到Copy Bundle Resources构建阶段，XCode 7不会崩溃了。
