NSString variable to UITextField's text on Swift

Question

I need to fetch a NSString from the NSMutableDictionary and assign it to UITextField's text.

But I am getting an exception ; unexpectedly found nil while unwrapping an Optional value

When I log the string it writes to console.

My code is as below;

    let tempString:NSString! = tempDict.objectForKey("name") as? NSString

    NSLog("%@",tempString)

    cell.textLabel.text = tempString  //This line gives the exception

Well, if the string's okay, then it's probably the cell or the textLabel. Are you sure those aren't nil? Did you forget to connect one of them up in Interface builder? — Matt Gibson

var cell:UITableViewCell! = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? UITableViewCell if (cell == nil) { cell = UITableViewCell(style: UITableViewCellStyle.Subtitle,reuseIdentifier:cellIdentifier) } — erdemgc

You stop this by safely unwrapping cell.textLabel by adding an if statement.

if var label = cell.textLabel{
    label.text = "This is a title"
}

Hope this helps.. :)

You can Try This. It Helped to get out from the same problem I was having

let userName : NSString = result.valueForKey("name") as! NSString self.lblUserName.text = userName as String
