I am testing a on am iphone device, user is logged in facebook app.

In the do, catch block I get error error is message: The operation couldn’t be completed. (FacebookShare.ShareError error 0.) on line 895 in /Users/bogdanbarbulescu/Desktop/myStreet.com/myStreet.com/MessagesViewController.swift.


I found another suggestion on github:

 let content = FBSDKShareLinkContent()
 content.contentURL = URL(string: "https://developers.facebook.com")
 FBSDKShareDialog.show(from: self, with: content, delegate: self) 

However, I get error Use of unresolved identifier 'FBSDKShareLinkContent'. If click on on FBSDKShareLinkContent() and jump to definition, I do get to FBSDKSharingContent.h

What am I doing wrong here?

import UIKit
import FacebookShare
import FacebookCore
import FacebookLogin

 class MessagesVC 

 func invitePeopleTapped() 

 let alertController = UIAlertController(title: "Some title", message: "", preferredStyle: .actionSheet)
 let shareOnFacebook = UIAlertAction(title: "Share on Facebook", style: .default) _ in

 let linkContent = LinkShareContent(url: URL(string: "https://www.google.com")!, quote: "Discover & Talk ")

 let shareDialog = ShareDialog(content: linkContent)
 shareDialog.mode = .native
 shareDialog.failsOnInvalidData = true

 shareDialog.completion = result in
 print("the result is (result)")
 

 do 
 try shareDialog.show()
 catch 
 printsNow(message: error.localizedDescription)

 
 
 alertController.addAction(shareOnFacebook)
 self.present(alertController, animated: true, completion: nil)
 //end invitePeopleTapped

 //end class
