UIImagepickercontroller - Camera is not working - ios

Question

This is my imagepicker class
import UIKit
public protocol ImagePickerDelegate: AnyObject {
func didSelect(image: UIImage?)
}
open class ImagePicker: NSObject {
private let pickerController: UIImagePickerController
private weak var presentationController: UIViewController?
private weak var delegate: ImagePickerDelegate?
public init(presentationController: UIViewController, delegate: ImagePickerDelegate) {
self.pickerController = UIImagePickerController()
super.init()
self.presentationController = presentationController
self.delegate = delegate
self.pickerController.delegate = self
self.pickerController.allowsEditing = true
self.pickerController.mediaTypes = ["public.image"]
}
private func action(for type: UIImagePickerController.SourceType, title: String) -> UIAlertAction? {
guard UIImagePickerController.isSourceTypeAvailable(type) else {
return nil
}
return UIAlertAction(title: title, style: .default) { [unowned self] _ in
self.pickerController.sourceType = type
self.presentationController?.present(self.pickerController, animated:
true)
}
}
func openCamera() {
self.pickerController.sourceType = .camera
self.presentationController?.present(self.pickerController, animated: true)
}
func openPhotoLibrary() {
self.pickerController.sourceType = .photoLibrary
self.presentationController?.present(self.pickerController, animated: true)
}
public func present(from sourceView: UIView) {
let alertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
if let action = self.action(for: .camera, title: Localization.set(key: .take_photo)) {
alertController.addAction(action)
}
if let action = self.action(for: .savedPhotosAlbum, title: Localization.set(key: .camera_roll)) {
alertController.addAction(action)
}
if let action = self.action(for: .photoLibrary, title: Localization.set(key: .photo_library)) {
alertController.addAction(action)
}
alertController.addAction(UIAlertAction(title: Localization.set(key: .cancel), style: .cancel, handler: nil))
if UIDevice.current.userInterfaceIdiom == .pad {
alertController.popoverPresentationController?.sourceView = sourceView
alertController.popoverPresentationController?.sourceRect = sourceView.bounds
alertController.popoverPresentationController?.permittedArrowDirections
= [.down, .up]
}
self.presentationController?.present(alertController, animated: true)
}
private func pickerController(_ controller: UIImagePickerController, didSelect image: UIImage?) {
controller.dismiss(animated: true, completion: nil)
self.delegate?.didSelect(image: image)
} }
extension ImagePicker: UIImagePickerControllerDelegate {
public func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
self.pickerController(picker, didSelect: nil)
}
public func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
guard let image = info[.editedImage] as? UIImage else {
return self.pickerController(picker, didSelect: nil)
}
self.pickerController(picker, didSelect: image)
} }
extension ImagePicker: UINavigationControllerDelegate {
}
This is how I used this class
self.imagePicker = ImagePicker(presentationController: self, delegate: self)
//MARK:- ImagePickerDelegate
extension AddEditGroupViewController: ImagePickerDelegate {
func didSelect(image: UIImage?) {
if let wnwrappedImage = image , let imageData = wnwrappedImage.jpegData(compressionQuality: 0){
self.changePhotoView.profileImageView.image = wnwrappedImage
imageParams = ["group_photo" : imageData]
}
}
}
It's working fine for photo gallery and saved photo album but When I try to open camera, it's giving me error as follows
**[Camera] Failed to read exposureBiasesByMode dictionary: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: data is NULL" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: data is NULL}**
Any help would be appreciated
