AppleLog Sampler

This is sample app for capture with .appleLog color mode.

How

1. Set automaticallyConfiguresCaptureDeviceForWideColor of AVCaptureSession to false (this might be the most important part)
2. Search for a format in formats of AVCaptureDevice that contains .appleLog in supportedColorSpaces and set it as activeFormat
3. Set activeColorSpace = .appleLog on AVCaptureDevice

private func isAppleLogAvailable(for device: AVCaptureDevice) -> Bool {
    device.formats.first(where: {
        $0.supportedColorSpaces.contains(.appleLog)
    }) != nil
}

private func configureAppleLogIfNeeded(for device: AVCaptureDevice) throws {
    guard isAppleLogAvailable(for: device) else {
        return
    }

    try device.lockForConfiguration()
    defer {
        device.unlockForConfiguration()
    }

    /// set up for .appleLog
    if let format = device.formats.first(where: {
        $0.supportedColorSpaces.contains(.appleLog)
    }) {
        device.activeFormat = format
        device.activeColorSpace = .appleLog
    }
}
