问题描述
我正在使用 Sierra版本10.12.6和Xcode 8.3 ，我在Storyboard中有3个场景，这些场景都通过推送选择相互连接。
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和一个具有imageView和一个单元格4个标签。
第三个场景的tableView的单元格包含3个标签，而collectionView的collectionView的单元格具有imageView。
当我尝试调整第三个场景时，第一个和第二个场景会自动更新以匹配第三个场景中的相同元素，然后Xcode崩溃。
仅当我尝试对第三个场景进行调整时，才会出现问题。
在第三个场景中，我尝试从其视图控制器断开所有对象的连接，然后进行调整，但第一个和第二个场景仍然重复所有操作，Xcode崩溃且何时发生重新打开所有连接仍然有效（就像我从未断开连接一样）。
然后我断开了场景之间的连接，但是发生了同样的确切问题-一旦我做出调整到第三个场景后，其他两个场景将更新为匹配，然后发生崩溃。
崩溃后，我打开项目后，一切恢复正常。
第三个场景一直向右，里面有粉红色：
在对第三个场景进行调整之前：
我对第三项进行调整之后场景：
我尝试用深层清洁（定期清洁）清洁项目，删除派生数据，完全卸载Xcode，然后再次重新安装，但问题仍然存在。
为什么另两个场景会自动更新以匹配第三个场景？
以下是崩溃日志：

由于您的library / caches文件夹中的IBCocoaTouchAutolayoutArbitrationUnit.m文件，Xcode崩溃了。根据此，您可以删除库中的文件/ caches文件夹（请勿删除该文件夹本身），您应该可以。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。
I'm working on Sierra version 10.12.6 and Xcode 8.3, I have 3 scenes in Storyboard that are all connected to one another via push segues.
The 1st scene has a tableView and a cell with an imageView and 2 labels.
The 2nd scene has a tableView and a cell with an imageView and 4 labels.
The 3rd scenes has a tableView with a cell that contains 3 labels and a collectionView with a cell that has an imageView.
When I try to make adjustments to the 3rd scene the 1st and 2nd scene automatically updates to match the same exact elements that are on the 3rd scene and then Xcode crashes.
The problem only happens when I try to make adjustments to the 3rd scene.
On the 3rd scene I tried to disconnect all the objects from it's view controller and then make the adjustments but the 1st and 2nd scene still duplicates everything, Xcode crashes and when it reopens all of the connections are still alive (as if I never disconnected them).
I then disconnected the segues between the scenes but the same exact problem occurs -once I make an adjustment to the 3rd scene the other two scenes update to match and then there is a crash.
After the crash once I open the project everything is back to normal.
The 3rd scene is the all the way to the right and has pink inside of it:
Before I make an adjustment on the 3rd scene:
After I make an adjustment to the 3rd scene:
I tried cleaning the project with a deep clean, a regular clean, deleting derived data, completely uninstalled Xcode then reinstalled it again but the problem still occurs.
Why are the other 2 scenes automatically updating to match the 3rd scene?
Here are the crash logs:

Xcode is crashing because of the the IBCocoaTouchAutolayoutArbitrationUnit.m file in your library/caches folder. According to this link, you can just delete the files in your library/caches folder (don't delete the folder itself) and you should be fine. That should fix the problem. But to play it on the safe side, you probably should move this file to another location instead of deleting. Also try opening your workspace in Xcode 9 beta to see if it crashes the same way with the same error message.
这篇关于iOS Xcode-编辑情节提要对象导致视图控制器场景中的场景重复另一个场景，然后Xcode崩溃的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
