title: Swift UITableViewCell has overlapping text while scrolling
body: <p>I am using UITableView and UITableViewCell in Swift and each time I scroll down, the cells overlap additional information on the cell and the data is unreadable. In this code, I am simply using an array of Doubles prin I know this has something to do with reusable cells, but I'm not sure how to fix this. Any help would be appreciated. </p>
  
  <pre><code>override func numberOfSectionsInTableView(tableView: UITableView) -&gt; Int {
          return 1
      }
  
      override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
          return allNumbers.count
      }
  
      override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell {
          let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
  
  
          configureCell(cell, number: allNumbers[indexPath.row])
  
          return cell
      }
  
  
  
      func configureCell(cell: UITableViewCell, number: Double) {
          //let object = self.fetchedResultsController.objectAtIndexPath(indexPath) as NSManagedObject
          //cell.textLabel.text = object.valueForKey("timeStamp")!.description
  
  
          var doubleLabel = UILabel(frame: CGRectMake(145, 10, 77, 21))
          var doubleInput = UILabel(frame: CGRectMake(230, 10, 77, 21))
  
          //add all to cell
          cell.self.addSubview(doubleLabel)
          cell.self.addSubview(doubleInput)
  
          //label text setter
          doubleLabel.text = "Double: "
          doubleInput.text = String(format:"%.1f", number)
      }
  </code></pre>
