xcode build failed no explanation
提问by user987723
My project has weirdly started failing with no error messages. Ive tried cleaning the project and this had no effect. I know this is all a bit vague but i havent done anything to revert or undo. its just randomly started to happen. Can anyone suggest a way of debugging what the problem is?
我的项目奇怪地开始失败，没有错误消息。我试过清理项目，但这没有效果。我知道这有点含糊，但我没有做任何事情来恢复或撤消。它只是随机开始发生。任何人都可以提出一种调试问题的方法吗？

Have you tried clearing the derived data (Organizer->Projects / cmd + shift + 2) and then cleaning (cmd+shift+K)?
您是否尝试过清除派生数据（Organizer->Projects / cmd + shift + 2）然后清理（cmd+shift+K）？
Maybe closing xCode and rebooting?
也许关闭 xCode 并重新启动？
I've had it a few times and this worked for me sometimes.
我已经有几次了，这有时对我有用。

I had the same issue. If you're using non-arc code in arc project, make sure you added "-fno-objc-arc" flags to .m files. instruction
我遇到过同样的问题。如果您在 arc 项目中使用非 arc 代码，请确保将“-fno-objc-arc”标志添加到 .m 文件。操作说明

I needed to re-clone my git repository to see what the build issue actually was. In my case the build issue was related to a dev provisioning profile that was no longer valid. I was able to correct this easily and the build properly.
我需要重新克隆我的 git 存储库以查看构建问题的实际情况。在我的情况下，构建问题与不再有效的开发配置文件有关。我能够轻松地纠正这一点，并正确构建。
