Hi! I am using a camera with swift playgrounds on iPad, but it is not showing up,
here is the code
import AVFoundation
var preview: AVCaptureVideoPreviewLayer?
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
// create a capture session for the camera input
let captureSession = AVCaptureSession()
captureSession.sessionPreset = AVCaptureSessionPresetPhoto
// Choose the back camera as input device
let backCamera = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo)
var error: NSError?
var input: AVCaptureDeviceInput!
do {
input = try AVCaptureDeviceInput(device: backCamera)
} catch let cameraError as NSError {
error = cameraError
input = nil
}
// check if the camera input is available
if error == nil && captureSession.canAddInput(input) {
// ad camera input to the capture session
captureSession.addInput(input)
let photoImageOutput = AVCapturePhotoOutput()
// Create an UIlayer with the capture session output
photoImageOutput.photoSettingsForSceneMonitoring = AVCapturePhotoSettings(format: [AVVideoCodecKey: AVVideoCodecJPEG])
if captureSession.canAddOutput(photoImageOutput) {
captureSession.addOutput(photoImageOutput)
preview = AVCaptureVideoPreviewLayer(session: captureSession)
preview?.videoGravity = AVLayerVideoGravityResizeAspectFill
preview?.connection.videoOrientation = AVCaptureVideoOrientation.portrait
preview?.frame = cameraView.frame
cameraView.layer.addSublayer(preview!)
captureSession.startRunning()
}
}
What did I Miss?
