Unity build to xcode with gives error: Apple Mach-O Linker
提问by Kevin Chen
I tried to google for the solution. I tried to delete the DerivedData folder but it still doesn't work... Why is this still happening? I am using Xcode version 6.2. Thanks.
我试图谷歌寻找解决方案。我试图删除 DerivedData 文件夹，但它仍然不起作用......为什么这仍然发生？我正在使用 Xcode 6.2 版。谢谢。
Edit: Under the one error has 70 different errors saying various things. There is a warning saying ld: warning: ignoring file /Users/Kevin Chen/Desktop/Parking Director/Libraries/libiPhone-lib.a, missing required architecture arm64 in file /Users/Mushrooms4Eva/Desktop/Parking Director/Libraries/libiPhone-lib.a (2 slices)
编辑：在一个错误下有 70 个不同的错误，说明了各种各样的事情。有一条警告说ld：警告：忽略文件/Users/Kevin Chen/Desktop/Parking Director/Libraries/libiPhone-lib.a，在文件/Users/Mushrooms4Eva/Desktop/Parking Director/Libraries/libiPhone-中缺少所需的架构arm64- lib.a（2 片）

Sounds like your library libiPhone-lib.ais not compiled for arm64, but your project is set to be compiled for this architecture.
听起来您的库libiPhone-lib.a未针对 编译arm64，但您的项目已设置为针对此体系结构进行编译。
I think all the errors are triggered by this "warning" as the library is ignored, and therefore you may have a lot of missing references.
我认为所有错误都是由这个“警告”触发的，因为库被忽略了，因此你可能有很多缺失的引用。
Your options:
您的选择：
- Get a version of the lib compiled for
arm64, or do it yourself, if you have the code - Remove
arm64architecture from your project (which I don't recommend, as you'll need to provide an 64bit build for the App Store, but that's another story)
- 获取为 编译的 lib 版本
arm64，或者自己动手（如果您有代码） arm64从您的项目中删除架构（我不推荐这样做，因为您需要为 App Store 提供 64 位版本，但这是另一回事）
