在GM Xcode(和iOS 11)之前运行良好.现在我收到这些错误:
Apple Mach-O Linker (ld) Error Group

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
它指向的一些行是:
photoSettings = AVCapturePhotoSettings(rawPixelFormatType: OSType(self.photoOutput.availableRawPhotoPixelFormatTypes.first!))
photoSettings.previewPhotoFormat = [kCVPixelBufferPixelFormatTypeKey as String: photoSettings.availablePreviewPhotoPixelFormatTypes.first!.uint32Value,
kCVPixelBufferWidthKey as String: 3024, kCVPixelBufferHeightKey as String: 3024]
也:
let rawFormat = self.photoOutput.availableRawPhotoPixelFormatTypes.first!.uint32Value
photoSettings = AVCapturePhotoSettings(rawPixelFormatType: OSType(rawFormat),
processedFormat: [AVVideoCodecKey : AVVideoCodecJPEG,
AVVideoCompressionPropertiesKey : [AVVideoQualityKey : 1.0]] …
