I would like to choose any picture from image gallery instead of the one named "mona-lisa" located in Assets. Is it possible?

func addPainting(_ hitResult: ARHitTestResult, _ grid: Grid) {



    // 1.

    let planeGeometry = SCNPlane(width: 0.2, height: 0.35)

    let material = SCNMaterial()

    material.diffuse.contents = UIImage(named: "mona-lisa")

    planeGeometry.materials = [material]



    // 2.

    let paintingNode = SCNNode(geometry: planeGeometry)

    paintingNode.transform = SCNMatrix4(hitResult.anchor!.transform)

    paintingNode.eulerAngles = SCNVector3(paintingNode.eulerAngles.x + (-Float.pi / 2), paintingNode.eulerAngles.y, paintingNode.eulerAngles.z)

    paintingNode.position = SCNVector3(hitResult.worldTransform.columns.3.x, hitResult.worldTransform.columns.3.y, hitResult.worldTransform.columns.3.z)



    sceneView.scene.rootNode.addChildNode(paintingNode)

    grid.removeFromParentNode()

}

As was mentioned above you can use UIImagePickerController for picking images from image gallery.

Here small example how to use it.

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {



@IBOutlet var imageView: UIImageView!



let imagePicker = UIImagePickerController()





@IBAction func loadImageButtonTapped(sender: UIButton) {

    imagePicker.allowsEditing = false

    imagePicker.sourceType = .photoLibrary // The defined source type means the you take images from system gallery.



    present(imagePicker, animated: true, completion: nil)

}



override func viewDidLoad() {

    super.viewDidLoad()



    imagePicker.delegate = self

}



// MARK: - UIImagePickerControllerDelegate Methods



func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any])  {

    if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {

        imageView.contentMode = .scaleAspectFit

        imageView.image = pickedImage // Here you have the image which was picked in gallery.

    }



    dismiss(animated: true, completion: nil)

}



func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {

    dismiss(animated: true, completion: nil)

}



}
