Hey guys, is it possible to use the font facing mac camera from xcode playgrounds in mac? I am trying to access the camera but i am unable to do so. The code works fine in Xcode but not in Xcode playgrounds. My app relies on the front facing camera and also I do not have an iPad to work on this project. This is the code I am using to access the camera:let captureSession = AVCaptureSession() var captureDevice: AVCaptureDevice!func prepareCamera() { captureDevice = AVCaptureDevice.default(for: AVMediaType.video) beginSession() } func beginSession() { do { let input = try AVCaptureDeviceInput(device: captureDevice) captureSession.addInput(input) } catch { } captureSession.beginConfiguration() captureSession.sessionPreset = .vga640x480 let dataOutput = AVCaptureVideoDataOutput() dataOutput.videoSettings = [kCVPixelBufferPixelFormatTypeKey as String: Int(kCVPixelFormatType_420YpCbCr8BiPlanarFullRange)] dataOutput.alwaysDiscardsLateVideoFrames = true if captureSession.canAddOutput(dataOutput) { captureSession.addOutput(dataOutput) } captureSession.commitConfiguration() let queue = DispatchQueue(label: "captureQueue") dataOutput.setSampleBufferDelegate(self, queue: queue) captureSession.startRunning() }Any help would be appreciated.

There are multiple tableviews in my app, but the tableview with fixed cell size have no problem. However, 2 tableviews that I am using have variable cell size and it is causing lag/stuttering(when the cells with greater height value appears). I initially thought thats maybe because my cell is designed very inefficiently. However even simple table view cells with just a textfield(variable height) and a label(fixed height) is causing stuttering.Layout constraints of the cell:1. Label is given a height os 20, pinned 0 from the bottom with 5px trailing and leading2. TextView is pinned 0 from top and 0 to the label below it with 5px trailing and leadingI have tried everything and looked at many articles but I am not able to find any helpful solution. Here is the cell file:import UIKitclass ConvoCell: UITableViewCell { @IBOutlet weak var messageView: UITextView! @IBOutlet weak var BgViewRightContraint: NSLayoutConstraint! @IBOutlet weak var BgViewLeftContraint: NSLayoutConstraint! @IBOutlet weak var TimingInfo: UILabel! @IBOutlet weak var bgView: UIView! override func awakeFromNib() { super.awakeFromNib() // Initialization code } func datainit(message: String, time: String, type: Int32){ self.messageView.text = message self.TimingInfo.text = time if (type == 1){ bgView.backgroundColor = .orange self.messageView.textColor = .white BgViewRightContraint.constant = 5 BgViewLeftContraint.constant = 50 TimingInfo.textColor = .white } else { bgView.backgroundColor = .white self.messageView.textColor = .black self.TimingInfo.textColor = .black BgViewRightContraint.constant = 50 BgViewLeftContraint.constant = 5 } }}Here is the code for my cellForRowAt:func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { guard let cell = tableView.dequeueReusableCell(withIdentifier: "messageBubble") as? ConvoCell else { return UITableViewCell() } cell.selectionStyle = .none messagetable.separatorStyle = .none var currentMessage: Message! currentMessage = chat.fetchedMessages[indexPath.row] cell.datainit(message: currentMessage.body!, time: currentMessage.timingInfo!, type: currentMessage.type) return cell }In viewdidLoad(), i have added the estimated rowHeight and the automatic dimensions as well:messagetable.estimatedRowHeight = 185 messagetable.rowHeight = UITableView.automaticDimension

I am using speech Synthesizer to convert text to speech and then using the speech recognizer to take inputs from the user. Based on the user input, a new View controller is presented, where again speech synthesizer is used along with voice recognition. The process works perfectly on the simulator. However, when I run it on a physical device, after going to the second VC, the speech synthesizer volume is extremely low(It works perfectly on the first VC and I am also stopping the voice recognizer and deleting the node in the first VC). I tried manually setting the volume of the synthesizer to 1, but that doesnt make any difference.The strange thing is that it works perfectly fine if I plug in a head phone to my iPhone. This is really strange. Someone please help!
