Xcode 9 GM未定义的架构arm64符号
[英]Xcode 9 GM undefined symbols for architecture arm64
问题描述
In Xcode 9's GM release, I am getting some compile-time errors for undefined symbols for architecture arm64 , namely for AVFoundation with: 
在Xcode 9的GM版本中，我undefined symbols for architecture arm64得到了一些编译时错误，即AVFoundation：
-
AVCapturePhotoOutput().supportedFlashModes -
AVCapturePhotoSettings().availablePreviewPhotoPixelFormatTypes
In both cases, using their "undocumented" __supportedFlashModes / __availablePreviewPhotoPixelFormatTypes builds just fine. 在这两种情况下，使用他们的“未记录的” __supportedFlashModes / __availablePreviewPhotoPixelFormatTypes构建就好了。
- Has anybody encountered the same issues in other frameworks? 有没有人在其他框架中遇到过同样的问题？
- API does not document such breaking changes , is this a bug? API没有记录这些重大变化 ，这是一个错误吗？

They were "inadvertently" marked private. 他们被“无意中”标记为私人。 Should be reverted with next release I guess? 应该用下一个版本还原我猜？ Workaround above is recommended by Apple. Apple建议使用上述解决方法。
