Question

尝试构建一个我一直在开发的 iOS 应用程序。由于 Interface Builder Storyboard 错误，该应用程序无法在 Xcode 中构建。错误说明如下:第 1917 行:文档末尾的额外内容。因为我不太了解 XML，所以我不确定这意味着什么。我继续查看 1917 行，没有发现任何异常。我已经粘贴了下面的代码。

第 1917 行: <-- 此行出现在文档末尾但不会显示

Answer 1

我刚遇到同样的问题。我认为它发生了我拉动并进行了合并以解决冲突。当它说 Extra Content at end of Document </document>我认为它在 xml 中找到额外的标签。所以我点击了版本编辑器并检查了更改的内容并找到了额外的标签。单击并放弃更改，一切顺利。

检查屏幕截图。

如果有人对此有详细了解，请随时编辑并向其添加更多详细信息。
