打开特定项目打开特定项目时，Xcode会重复崩溃。
打开另一个项目似乎很好。触摸条似乎正在产生一些问题。关于如何解决这个问题的任何想法。
在没有触控条的情况下在不同的MacBook上打开项目似乎很好。
从日志中我可以看到这与NSTouchBarFinder和IDE不符合KVO有关吗？
我一直收到此崩溃日志：
System Integrity Protection: enabled

UNCAUGHT EXCEPTION (NSInternalInconsistencyException): Cannot update for observer <NSTouchBarFinder 0x7fee281263e0> for the key path "_keyWindow.firstResponder" from <IDEApplication 0x7fee22f0b1c0>, most likely because the value for the key "_keyWindow" has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the IDEApplication class.

即使使用Xcode 9.0.0版本，我今天早上也遇到了同样的问题。
通过删除xcuserdatad文件夹中的project.xcworkspace文件夹（以您的用户名为前缀），我成功绕过了xcode启动时的崩溃。
