在将 Xcode 升级到 6.3 之后，故事板文件之前是使用 Xcode6.0 创建的。编译错误会以晦涩难懂的错误消息跳出。我花了几个小时搜索，但仍然没有弄清楚有问题的项目在我的故事板文件中到底是什么/在哪里。

非常感谢您的时间/建议等。

以下是完整的错误消息：

如果您尝试向不在视图层次结构中的视图添加约束，就会发生这种情况。自动布局限制。

我继续使用 Xcode 6.3 并执行了以下操作：

我找出了哪个以编程方式创建的约束导致了问题（通过在调试中运行代码并查看何时发生崩溃）。然后我调试到这一点，并在添加约束时检查约束中的两个视图都不是空的。其中之一是。我解决了这个问题，错误消失了。

最后用一种可行的（虽然不是有效的）方法解决了这个问题：

通过从情节提要中删除其他视图场景，以“二分搜索”方式缩小范围以定位有问题的视图场景。

在确定有问题的视图后，我重新设置了视图及其约束。然后，构建成功。

在这里分享它，因为它可能对其他人有用。

这就是我解决问题的方法：我将情节提要文件复制到我的 Windows 机器上，并使用 Linq to XML 编写了一个小 C# 程序来查找虚假约束，该约束具有“firstItem”属性但缺少“secondItem”属性。基本上只有一行：

        var nosecondCons = xdoc.Descendants("constraint").Where(p => p.Attribute("secondItem") == null && p.Attribute("firstItem") != null);
