Segue from collection view cell to table view cell

This is giving me a very hard time. I am trying to segue from a collection view cell to a table view controller. When I click on a cell (specifically a button within a cell) I should be able to segue to the table view controller and have details of the cell clicked within the table view controller's cells.

In my view controller with the collection view cells, I have implemented a segue. 

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {       
        }
        override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
            if segue.identifier == "details" {
    if segue.identifier == "UsersProfile" {

                if let indexPath = sender as? IndexPath{
                    let vc = segue.destination as! UsersProfileViewController
                    let post = self.posts[indexPath.row] as! [String: AnyObject]
                    let posted = self.posts[indexPath.row] as! [NSMutableArray: AnyObject]
                    let username = post["username"] as? String
                    let userpicuid = post["uid"] as? String
                    let userpostuid = posted["uid"] as? NSMutableArray
                    vc.username = username
                    vc.userpicuid = userpicuid
                    vc.posts = userpostuid
                     print(indexPath.row)
                }
            }}

When I segue, the userpic and username appear in the detailed table view just fine but they are not viewed within the table view cells. This is my code for the table view controller: 

     var posts = NSMutableArray()
 @IBOutlet var TableView: UITableView!

     func numberOfSections(in tableView: UITableView) -> Int {
            // #warning Incomplete implementation, return the number of sections
            return 1
        }

        func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
                return self.posts.count

              }
        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let cell = tableView.dequeueReusableCell(withIdentifier: "UsersCell", for: indexPath) as! UserProfileTableViewCell

            //Configure the cell


            print(posts[indexPath.row])
            let post = self.posts[indexPath.row] as! [String: AnyObject]
            cell.Title.text = post["title"] as? String
            cell.Author.text = post["Author"] as? String
            cell.Price.text = post["Price"] as? String

            if let imageName = post["image"] as? String {

                let imageRef = FIRStorage.storage().reference().child("images/\(imageName)")


                imageRef.data(withMaxSize: 25 * 1024 * 1024, completion: { (data, error) -> Void in
                    if error == nil {


                    }else {

                        print("Error downloading image:" )
                    }})}

            return cell
            }

Nothing shows up in the table view cell. I am new to swift and I have been trying so hard to find a solution to this but I can't.

I have created a sample that will navigate you to the tableViewController when user will tap on UICollectionViewCell.

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {

// Change it with your required items.
return 10
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "YOUR_CELL_IDENTIFIER", for: indexPath as IndexPath)

// Do not forgot to set cell tag.
cell.tag = indexPath.row//cell tag has been set to indexpath.row

return cell
}

In order to navigate to your tableViewController implement PrepareForSegue like mentioned below.

override func prepare(for segue: UIStoryboardSegue, sender: Any!) {

if segue.identifier == "UsersProfile" {

// Use this tag to pass data for the selected cell
//this tag will act as indexpath.row

guard let tag = (sender as? UIView)?.tag
else {
 return
}

// add the data you want to parse here.
print(tag)
}
}

NOTE: Make sure that you have set the segue in your storyboard file from UICollectionViewCell to your UITableViewController.

In case you required further details, please let me know i will add it to the answer.

Did you add the Delegate and Datasource of you tableview to the class?
