【中文标题】编辑 XIB 时 XCode 7.3 崩溃【英文标题】：XCode 7.3 crashes when editing XIB 【发布时间】：2016-06-14 18:57:41 【问题描述】：我有一个编译和运行良好的 XCode 项目，但是当我将元素添加到特定 XIB 的 UI 时，当我尝试保存或 XCode 失去焦点时，它会使 XCode 崩溃。查看崩溃的错误数据，它似乎是与 NSTableHeader 相关的断言失败，但我不明白从那里去哪里？我没有使用自动布局，这是一个 OSX 应用程序。

【问题讨论】：
【参考方案1】：我遇到了类似的问题，我认为这是因为我的 XIB 文件很旧（来自 XCode 4.6 或更早版本）。从那时起，xml-schema 发生了重大变化。 （请参阅this article。）我能够通过从 Time Machine 中获取 XCode 6 并在应用程序中与 XCode 7 一起复制来对我需要进行的 XIB 进行更改。我没有尝试使用 XCode 6 打开任何项目，但我直接打开了 XIB 并在项目之外进行了我需要进行的更改。
奇怪的是，我只能在几周前修改这些 XIB 文件之一。 XCode (7) 然后用新模式完全重写了 XML，现在编辑那个 XIB 没有问题。此外，如果我尝试将 XIB 升级到更新的模式，即使 XCode 6 现在也会崩溃。 （我想我只能编辑我的 XIB，因为 XCode 6 与 XCode 7 不同，仍然可以编辑旧架构而不升级它。）
我认为 Apple 可能在过去几周推出了 XCode 外部的软件更新，但仍然破坏了 xml 升级。或者是我做过的其他事情，但我想不出它会是什么。
FWIW：我在 10.11.5，所以至少 XCode 6 的 Interface Builder 部分仍然可以在最新的操作系统上运行。
编辑：我能够升级 XML，因此能够使用稍微复杂的解决方案在 XCode 7.3.1 中编辑 XIB：
-
使用 Fusion 或 Parallels 创建 10.8 虚拟机。
在虚拟机中安装 XCode 5.1.1。 （您可以找到下载链接here。）
在 XCode 5.1.1 中打开 XIB 并升级它。您现在可以打开它并将其保存在 XCode 7 中。
【讨论】：
谢谢，您的回答很有道理。我的项目已有好几年了，我怀疑您对 XML 模式更改的看法是正确的。幸运的是，我能够将我的问题追踪到可以删除的 NSTableView 上，现在一切看起来都很开心。以上是关于编辑 XIB 时 XCode 7.3 崩溃的主要内容，如果未能解决你的问题，请参考以下文章
