title: converted image for tableview yielding "unexpectedly found nil while unwrapping optional"
body: <p>When I retrieve all the information for an image from my GET request in JSON I attempt to convert the string I'm getting into an image. It comes to me as a base64 string which i convert to NSData and then I try to put it in the imageView but I keep getting an "unexpectedly found nil while unwrapping optional" error. I printed the NSData to my console before unwrapping it in my imageView line(to show it's not nil) and I get the output of </p>

  <p>it's MUCH longer but this is just to give an idea.</p>
  
  <p>Here is my code where I'm getting the issue:</p>
  
  <pre><code>//Convert image here
          let base64String = media[indexPath.row].image
          let decodedData = NSData(base64EncodedString: base64String, options: NSDataBase64DecodingOptions(rawValue: 0))
          print(decodedData)
  
          cell.mediaImageView.image = UIImage(data: decodedData!)
  </code></pre>
