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

I use UIImagePickerController to take a photo by camera of iPhone.

I want to show both "take a photo" and "choose a photo".

My code

imagePicker =  UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .camera
//imagePicker.sourceType = .PhotoLibrary
presentViewController(imagePicker, animated: true, completion: nil)

I tried to use imagePicker.sourceType = .Camera and imagePicker.sourceType = .PhotoLibrary together to do this, but it doesn't work...

Thank you

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:

/// Button action
@IBAction func btnChooseImageOnClick(_ sender: UIButton) {
    
    let alert = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
    alert.addAction(UIAlertAction(title: "Take Photo", style: .default, handler: { _ in
        self.openCamera()
    }))
    
    alert.addAction(UIAlertAction(title: "Choose Photo", 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 in 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)
}

/// Open the camera
func openCamera() {
    if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerController.SourceType.camera)){
        imagePicker.sourceType = UIImagePickerController.SourceType.camera
        //If you dont want to edit the photo then you can set allowsEditing to false
        imagePicker.allowsEditing = true
        imagePicker.delegate = self
        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)
    }
}

/// Choose image from camera roll
func openGallary() {
    imagePicker.sourceType = UIImagePickerController.SourceType.photoLibrary
    // If you don't want to edit the photo then you can set allowsEditing to false
    imagePicker.allowsEditing = true
    imagePicker.delegate = self
    self.present(imagePicker, animated: true, completion: nil)
}

Delegate implementation - UIImagePickerControllerDelegate, UINavigationControllerDelegate:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    // Get the image from the info dictionary.
    if let editedImage = info[.editedImage] as? UIImage {
        self.imgProfile.image = editedImage
    }
    
    // Dismiss the UIImagePicker after selection
    picker.dismiss(animated: true, completion: nil)
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    picker.isNavigationBarHidden = false
    self.dismiss(animated: true, completion: nil)
}
