swift 3 UITableView

Question

I'm a newbie.
But I do not understand why the UITableView was not all elements loads (10 element in array).
With Xcode7 works but with Xcode8 (Swift 3) no.
I rewrote the code but to no avail: one element is being loaded ...

This is the code inside the UIViewController (with extension UITableViewDelegate, UITableViewDataSource)

CODE:

// MARK: UITableView
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return commentArray.count
}

// cell height
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true  
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = mytableView.dequeueReusableCell(withIdentifier: "CellComment", for: indexPath ) as! commentCell


    // connect objects with our information from arrays
    cell.usernameBtn.setTitle(usernameArray[indexPath.row], for: UIControlState.normal)
    cell.usernameBtn.sizeToFit()
    cell.commentLbl.text = commentArray[indexPath.row]
    return cell
}

I think the problem is in the cellForRowAt....
I also have the following error:

BFTask caught an exception in the continuation block. This behaviour is discouraged and will be removed in a future release. Caught Exception: Invalid index path for use with UITableView. Index paths passed to table view must contain exactly two indices specifying the section and row. Please use the category on NSIndexPath in UITableView.h if possible.

I do not understand. Does anyone have an idea? Thank you

You need to use following lines inside CellForRowAt IndexPath:

let cellIdentifier = "CellComment"
let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier) as UITableViewCell?
