unexpectedly found nil while unwrapping an Optional value in SWIFT 3.0

Question

I am using tableview with custom cell in swift 3.0. I take a textview and give outlet of class of tabelview cell and accessing in tableview delegate method but its showing me error like unexpectedly found nil while unwrapping an Optional value

here is my code. Record is array

Chek this Screenshot. FYI I have taken A new custom class and Give Outlet to it but same problem ocuured

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



func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    tableView.register(TableViewCell.self, forCellReuseIdentifier: "TableViewCell")
   let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as! TableViewCell

  if let str = record.object(at: indexPath.row) as? String {
        print(cell.txtview)

            cell.txtview.text = str  

    }


    return cell
}

Its perfectly working in Static cell but in custom cell it showing me error.

cell.textview is not taken from custom cell

Please help me with it

what is the identifier of your custom cell, check that because of that might be the issue — Rahul Patel, Oct 15 '16 at 05:27
As per My code I gave it same Class and same identifier. But identifier is given as string so Its not an issue — Jitendra Modi, Oct 15 '16 at 05:29
No @JAL Its in siwft 3.0, If its in swift 2.0 or lower then I had solved it — Jitendra Modi, Oct 15 '16 at 05:31
Read the linked duplicate. It is Swift language version agnostic. — JAL, Oct 15 '16 at 05:32
@JAL you can not give its duplicate question because its lots of changes in swift 2.0 and swift 3.0 and ya no thats question is not a custom cell its tableview default cell . — Himanshu Moradiya, Oct 15 '16 at 05:41
Is your textview outleted? Means have you mapped it with cell(xib or from storyboard)? — Mehul Sojitra, Oct 15 '16 at 05:53
@MehulSojitra Yeah ,I Give outlet of textview withing tableviewcell class — Jitendra Modi, Oct 15 '16 at 05:53
Is this issue occuring on which line? its on :- cell.textview.text = string! as String ?? — Mehul Sojitra, Oct 15 '16 at 05:56
Please remove mapping of your text view and map it again. And make sure that is mapped with tableview cell. — Mehul Sojitra, Oct 15 '16 at 06:12

Guys, Just try this thing once and test it in xcode 8 If you dont found this error then downvote it — Jitendra Modi, Oct 15 '16 at 06:35
You are using a nib (Xib) file, so you can't simply dequeue the cell and expect outlets to be connected. That only works for prototype cells in storyboards. If you want to use a nib then you need to explicity load the nib if a cell can't be dequeued. You need to use `dequeueReusableCell` without passing an index path and then check for nil. If you get nil then load a new cell class instance from the nib. Using storyboards and prototype cells is much easier and you could use your existing code — Paulw11, Oct 15 '16 at 06:59
I have done in swift 2.2 ,xcode 7.3 and its working perfectly but I found this issue in swift 3.0, xcode 8.0 — Jitendra Modi, Oct 15 '16 at 07:01
Can you show the code where you are registering your nib and class for the reuse identifier. — Paulw11, Oct 15 '16 at 09:17
@Paulw11 In tableview delegate method I write code for registering nib file. I also tried that code in viewdidload but nothing helps — Jitendra Modi, Oct 15 '16 at 09:21
I just set up a quick test project in xcode8 that uses a Xib file and it worked without any issues. You should register the nib in viewdidload — Paulw11, Oct 15 '16 at 09:43
@Paulw11 Can you send me project on jiten.benzatine@gmail.com ? Please I need to know why its crashing — Jitendra Modi, Oct 15 '16 at 09:44

Please try with following line not sure about that:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        tableView.register(TableViewCell.self, forCellReuseIdentifier: "TableViewCell")
         let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as! TableViewCell

        if let title = record.object(at: indexPath.row) as? String {
                cell.textview.text = title
        } else {
                cell.textview.text = ""
        }

        return cell
}

Which text did you got in title? - can you please post here. – Mehul Sojitra Oct 15 '16 at 06:09
I got this "I have a UITextView in a custom UITableViewCell. The textview delegate is assigned in the tableviewcell custom class." from array value – Jitendra Modi Oct 15 '16 at 06:12
