Macos Sierra。 Xcode 8.我可以打开一些项目，但是一个特定的项目会导致XCode在启动时崩溃。每一次。
以下是xcode崩溃日志的前200行。任何见解都会非常有帮助！

答案 0 :(得分：3)
请您尝试删除〜/ Library / Developer / Xcode / DerivedData
中的内容因为您的旧应用程序正在引用其他位置。
答案 1 :(得分：1)
删除.xcworkspace文件。 再次运行pod install以重新创建.xcworkspace文件。
为我工作。
答案 2 :(得分：0)
我感觉这次崩溃是由.xib文件引起的，该文件包含的数据不再与新版本的XCode兼容。所以我：
.xib文件内容的一半.xib文件如果它仍然崩溃，我继续删除剩下的一半数据。如果它没有崩溃，我推断borked数据必须在另一半。重复步骤1到3，直到不再有XCode崩溃。
此方法有效。以下数据是我.xib中崩溃的原因：
<navigationItem key="navigationItem" title="Custom Content" id="314">
<barButtonItem key="rightBarButtonItem" title="Edit" id="315">
<connections>
<action selector="editBookmarks:" destination="263" id="318"/>
</connections>
</barButtonItem>
</navigationItem>
我删除了<barButtonItem .../>中的<navigationItem .../>元素，XCode不再崩溃了。呼！
我的结论是，在早期版本的Xcode中，barButtonItem曾在navigationItem内被允许，但新版本无法迁移.xib的内容，并且没有优雅的方式警告，所以它很难崩溃。
如果您收到与我相同的错误，请检查xib是否barButtonItem嵌套在navigationItem内，删除它们并使用GUI重新添加内容。
如果嵌套barButtonItem 不导致您的崩溃，那么您必须在xib上重复我的强力方法，直到您单身在您的特定项目中输出错误的xml代码。祝你好运！
