问题描述
我有一个 XIB 文件，该文件一直运行到今天-当我尝试在Xcode中打开它时，沙滩球出现了，一分钟后Xcode崩溃了。其他 XIB 也可以。另外，如果我只是直接在我的设备上构建并运行项目，它也可以工作（而XIB在该应用程序中也可以工作）。
I had a XIB file which worked fine until today - when I try to open it in Xcode, the beachball appears and after 1 minute Xcode crashes. Others XIBs work just fine. Also, if I just build and run the project right to my device, its also work (and XIB works at the app).
这是错误消息：

推荐答案
您是否正在使用autoLayout属性？取消选中使用自动版式复选框，它应该可以正常工作。取消选中此选项，然后保存文件似乎可以更早地解决我的问题。请查看此链接以获取更多详细信息
Are you using the autoLayout Property ? Uncheck the checkbox that says Use AutoLayout and it should work fine. Unchecking this and then saving the file seems to fix the problem for me earlier. check this link for further details Xcode Interface Builder crashes when I edit storyboard
