Swift Programming cannot convert to float

Question

Attached is my code, it is basically two text boxes being added together, however I do not know how to handle float variables. Any help is appreciated

@IBOutlet weak var first: UITextField!
@IBOutlet weak var second: UITextField!
@IBOutlet weak var total: UILabel!

@IBAction func add(sender: AnyObject) {

   total.text = "\(first.text.toInt()!+second.text.toInt()!)"

He's trying to get total.text in a Float value instead of the toInt() part. — gran_profaci, Jul 07 '15 at 03:59

You could try

let firstFloatValue = (first?.text as NSString).floatValue
let secondFloatValue = (second?.text as NSString).floatValue

and then,

total.text = "\(firstFloatValue + secondFloatValue)

Or any one of the many techniques mentioned in Convert String to float in Apple's Swift

No Go - get the error that 'String?' is not convertible to NSString – JMac Jul 08 '15 at 02:21
