How to share an image from IOS app to Facebook?

Question

I am trying to share an image from my app to a user's Facebook page. I believe I have all the Facebook set up done correctly and the dialog pops up with the image and lets me go through all the motions, but nothing shows up in Facebook.

Here is my relevant code:

func shareFaceBook(){
    if let token = AccessToken.current, !token.isExpired {
        DispatchQueue.main.async {
            guard let gameView: UIView = self.view.viewWithTag(11000) else {return}
            gameView.backgroundColor = UIColor(red: 2/255.0, green: 44.0/255.0, blue: 232.0/255.0, alpha: 1.0)
            let image = UIImage(data: gameView.asJpeg!)!
            let photo = SharePhoto(
                    image: image,
                    userGenerated: true
            )
            let content = SharePhotoContent()
            content.photos = [photo]
            ShareDialog(fromViewController: self, content: content, delegate: self).show()
        }
    }
    else {
        fbLogIn()
    }
}

func sharer(_ sharer: Sharing, didCompleteWithResults results: [String : Any]) {

    if sharer.shareContent.pageID != nil {
        print("Share: Success")
    }
    else {
        print("No Page ID")
    }
}

and here are the issues it is telling me about that I am not sure if they are the problem or just warnings. Either way, I don't know what to do about it.
