How to make UIImagePickerController for camera and photo library at the same time in swift

Import UIImagePickerControllerDelegate and create a variable to assign UIImagePickerController
var imagePicker = UIImagePickerController() and set imagePicker.delegate = self.

Create an action sheet to display options for ‘Camera’ and ‘Photo library’.

On your button click action:

@IBAction func buttonOnClick(_ sender: UIButton)
{
    self.btnEdit.setTitleColor(UIColor.white, for: .normal)
    self.btnEdit.isUserInteractionEnabled = true
    
    let alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
    alert.addAction(UIAlertAction(title: "Camera", style: .default, handler: { _ in
        self.openCamera()
    }))
    
    alert.addAction(UIAlertAction(title: "Gallery", style: .default, handler: { _ in
        self.openGallary()
    }))
    
    alert.addAction(UIAlertAction.init(title: "Cancel", style: .cancel, handler: nil))
    
    /*If you want work actionsheet on ipad
    then you have to use popoverPresentationController to present the actionsheet,
    otherwise app will crash on iPad */
    switch UIDevice.current.userInterfaceIdiom {
    case .pad:
        alert.popoverPresentationController?.sourceView = sender
        alert.popoverPresentationController?.sourceRect = sender.bounds
        alert.popoverPresentationController?.permittedArrowDirections = .up
    default:
        break
    }
    
    self.present(alert, animated: true, completion: nil)
}


func openCamera()
    {
        if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerController.SourceType.camera))
        {
            imagePicker.sourceType = UIImagePickerController.SourceType.camera
            imagePicker.allowsEditing = true
            self.present(imagePicker, animated: true, completion: nil)
        }
        else
        {
            let alert  = UIAlertController(title: "Warning", message: "You don't have camera", preferredStyle: .alert)
            alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
            self.present(alert, animated: true, completion: nil)
        }
    }

    func openGallary()
    {
        imagePicker.sourceType = UIImagePickerController.SourceType.photoLibrary
        imagePicker.allowsEditing = true
        self.present(imagePicker, animated: true, completion: nil)
    }
