                        let userSnap = snap as! DataSnapshot
                        let userDict = userSnap.value as! [String: AnyObject]
                        let getPost = userDict["getPost"] as! String
                            print("Share Post: \(getPost)")

                        self.myTextView.text = getPost

var postsStr = ""
dataRef?.child("Users/\(userID)/Posts/").observeSingleEvent(of: .value, with:  { (snapshot) in
                    for snap in snapshot.children {

                    let userSnap = snap as! DataSnapshot
                    let userDict = userSnap.value as! [String: AnyObject]
                    let getPost = userDict["getPost"] as! String
                        print("Share Post: \(getPost)")
                    postsStr += "\(getPost) | "

                }
            })

         self.myTextView.text = postsStr
