xcode - iOS Xcode-编辑 Storyboard 对象导致 View Controller 场景中的场景重复另一个场景，然后Xcode崩溃

Question

我正在使用 Sierra版本10.12.6和Xcode 8.3 ，我在Storyboard中有3个场景，它们通过push segues相互连接。

第一个场景有一个tableView和一个带有imageView和2个标签的单元格。

第二个场景有一个tableView和一个带有imageView和4个标签的单元格。

第三个场景的tableView具有一个包含3个标签的单元格，而collectionView具有一个具有imageView的单元格。

当我尝试对第三个场景进行调整时，第一个和第二个场景会自动更新以匹配与第三个场景相同的元素，然后Xcode崩溃。

仅当我尝试对第三场景进行调整时，才会出现此问题。

在第三个场景中，我尝试从其 View Controller 断开所有对象的连接，然后进行调整，但是第一个和第二个场景仍然复制所有内容，Xcode崩溃，并且当它重新打开时，所有连接仍然有效(就像我从未断开连接一样) )。

然后，我断开了场景之间的顺序，但是发生了相同的确切问题-一旦我对第三个场景进行了调整，其他两个场景都进行了更新以匹配，然后发生崩溃。

崩溃后，一旦打开项目，一切都会恢复正常。

第三个场景一直在最右边，并且内部是粉红色的:

在对第三个场景进行调整之前:


对第三场景进行调整后:


我尝试使用深度清理，定期清理，删除派生数据，完全卸载的Xcode清理项目，然后再次重新安装它，但问题仍然存在。

为什么其他两个场景会自动更新以匹配第三个场景？



以下是崩溃日志:

由于库/缓存文件夹中的IBCocoaTouchAutolayoutArbitrationUnit.m文件，Xcode崩溃了。根据此link，您只需删除library / caches文件夹中的文件(不要删除文件夹本身)，就可以了。那应该解决问题。但是为了安全起见，您可能应该将此文件移到另一个位置而不是删除。另外，尝试在Xcode 9 Beta中打开工作区，以查看是否以相同的错误消息崩溃。
