Our apologies. For apps using Swift 3.2 or Swift 4.0, several AVFoundation capture APIs (public extensions on external protocol) were inadvertently marked private in Xcode 9.
The following AVFoundation API are temporarily unavailable:
* `AVCaptureDevice.Format.supportedColorSpaces`
* `AVCaptureDevice.supportedFlashModes`
* `AVCapturePhotoOutput.availablePhotoPixelFormatTypes`
* `AVCapturePhotoOutput.availableRawPhotoPixelFormatTypes`
* `AVCapturePhotoSettings.availablePreviewPhotoPixelFormatTypes`
As a workaround you can use the SwiftPrivate versions of these API by prepending each API with double underscore (`__`). For example, change `AVCaptureDevice.Format.supportedColorSpaces` to `AVCaptureDevice.Format.__supportedColorSpaces`.
