Unwrapping a Int to String cast in Swift

Question

I am gathering an NSNumber from my plist and I want to print that in a String:

let tijd = String(self.sortedHighscores[indexPath.row]["Tijd"]!)
cell.detailTextLabel?.text = "\(tijd) seconden"

But in Simulator I'm seeing printed: Optional(120) seconden for example. How do I solve this? I've tried unwrapping tijd, but that would result in errors in the compiler telling me to delete the !.

first yo have to unwrap then convert into string this is a duplicate of http://stackoverflow.com/questions/24161336/convert-int-to-string-in-swift — ogres, Jul 08 '15 at 12:46

Try this:

 var highscore : NSNumber =  self.sortedHighscores[indexPath.row]["Tijd"] as! NSNumber
 var a : String = String(format:"%d",highscore.integerValue)
 cell.detailTextLabel.text = a

A Swift String does not have the format initializer, according to my autocomplete? – jbehrens94 Jul 08 '15 at 12:56
That did not help, are you sure you didn't mean it to be `NSString`? – jbehrens94 Jul 08 '15 at 13:05
yes I am sure...just try to copy and paste and give it a try – iAnurag Jul 08 '15 at 13:05
I solved it like this: `let tijd:NSNumber = self.sortedHighscores[indexPath.row]["Tijd"] as! NSNumber` `let tijdStr:String = NSString(format: "%d", tijd.integerValue) as String` – jbehrens94 Jul 08 '15 at 13:06

tijd being an optional, you need to unwrap it, but you should check whether it has a value, too.

if let foo = tijd {
    cell.detailTextLabel?.text = "\(foo) seconden"
}

If you know it will always have a value, "\(tijd!) seconden" should work also.
