Try Sample Avcam from Apple Found Error

Try Sample AVCAM from apple found error

Update 15 Sept 2017:

Official response from Apple:

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.

I can confirm using __availablePreviewPhotoPixelFormatTypes fixes the build errors.

E.g.

let settings = AVCapturePhotoSettings()
let previewPixelType = settings.__availablePreviewPhotoPixelFormatTypes.first!

Weird compile error with AVCapture after updating to Xcode 9 / Swift 4

So I managed to solve this issue.

Somehow , with Xcode 9 you cannot have "free" code implemented that will not work on iOS Simulator.

The error - after solving it off - was pretty simple.

I cannot use the camera in the simulator, because it will not work.

I think Xcode could give more useful error information.

In order to solve this, in my CameraController class I had to edit my handleCapturePhoto() function.

I has to check that if the used architecture wasn't x86_64 (simulator) , then I could present the camera output.

This is the function solved state:

@objc func handleCapturePhoto() {
    // processes the captured photo
    let settings = AVCapturePhotoSettings()

    // doesn't show in the simulator
    #if (!arch(x86_64))
        guard let preview = settings.previewPhotoFormat?.first else { return }
        settings.previewPhotoFormat = [kCVPixelBufferPixelFormatTypeKey as String: preview]
        output.capturePhoto(with: settings, delegate: self)
    #endif
}

Hope this helps someone in the future.

How do I make use of SSLSetALPNProtocols?

As of the latest macOS and Xcode beta with Swift 4.1 I've got this up and running.
