Add pch file in you in xcode project to resolve this very easily.
在 xcode 项目中添加 pch 文件可以很容易地解决这个问题。
Make new file: ?cmd+N
iOS/Mac > Other > PCH File > YourProject-Prefix.pch.
Project > Build Settings > Search: "Prefix Header".
Under "Apple LLVM 6.0" you will get the Prefix Header key.
Type in: "YourProjectName/YourProject-Prefix.pch".
Clean project: ?cmd+?shift+K
Build project: ?cmd+B
新建文件：?cmd+N
iOS/Mac > 其他 > PCH 文件 > YourProject-Prefix.pch。
项目 > 构建设置 > 搜索：“前缀标题”。
在“Apple LLVM 6.0”下，您将获得 Prefix Header 键。
输入：“YourProjectName/YourProject-Prefix.pch”。
清理项目：?cmd+?shift+K

Here is an answer that might help someone very new like me on the x-code ios ecosystem:
这是一个答案，可能会在 x-code ios 生态系统中帮助像我这样的新手：
for me the answer was to change back to ios form OS X in the build settings I really don't know why I changed it in the first place (probably because it told me to change from beta and i figured here I can change to something that is not beta not realizing entirely what I'm doing).
对我来说，答案是在构建设置中改回 ios 形式的 OS X 我真的不知道为什么我首先要更改它（可能是因为它告诉我从 beta 更改，我想在这里我可以更改为某些内容）这不是测试版没有完全意识到我在做什么）。
After that and
在那之后和
Deleting Xcode Beta and reinstalling Xcode (6.1 - current stable)
Updating the ios, version of my device (iphone 4s to 8.1.2 latest)
Changing signature in Code signing identity to an acceptable one (Provisioning Profile -Automatic)
删除 Xcode Beta 并重新安装 Xcode（6.1 - 当前稳定）
更新 ios，我的设备版本（iphone 4s 到最新的 8.1.2）
将代码签名身份中的签名更改为可接受的签名（配置文件 - 自动）
Everything was going well, and I was able to submit the app via Xcode. P.s. maybe some of the heavy lifting of deleting wasn't necessary but it seemed to be the safest bet.
一切都很顺利，我能够通过 Xcode 提交应用程序。Ps 也许删除的一些繁重工作是不必要的，但它似乎是最安全的选择。
