cellForRow(at: IndexPath) in swift 3 is acting funny in XCode 8

I'm trying to recover a cell from a TableView using the method cellForRow(at: IndexPath) but the compiler doesn't seem to like this method because it won't let me call it :S

https://i.sstatic.net/Gf23z.jpg (Can't post images yet)

Here's the snippet of the code in question:

if let i = self.data.index(of: snapshot.value as! String) {

    self.data[i] = snapshot.value as! String

    self.tableView.cellForRow(at: i).textLabel!.text = "Modd"


    self.tableView.cellForRow(at: [IndexPath(row: i, section: 0)])!.textLabel!.text = "mod"
} 
else {

    print("Modified an item that wasn't in the data list")
}

How should I be calling the method if the compiler accepts neither of the two?

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
      let cell:UITableViewCell
      if let i = self.data.index(of: snapshot.value as! String) {

         self.data[i] = snapshot.value as! String

         cell = tableView.cellForRow(at: indexPath)!

         cell.textLabel!.text = "Modd"
      }
      else {

         print("Modified an item that wasn't in the data list")
      }

      return cell == nil ? UITableViewCell() : cell

   }

Your problem with your second statement is that you add the indexPath that you create to an array.

Use the following code:

self.tableView.cellForRow(at: IndexPath(row: i, section: 0))
