Answer 1

You can do something like this:

let labelWidth = CGRectGetWidth(label.bounds)

    let str = "You will have 30 seconds till you give us a good impression" as NSString
    let words = str.componentsSeparatedByString(" ")

    var newStr = "" as NSString

    for word in words{

        let statement = "\(newStr) \(word) ..." as NSString
        let size = statement.sizeWithAttributes([NSFontAttributeName:label.font])
        if size.width < labelWidth {
            newStr = "\(newStr) \(word)"
        }
        else{
           break
        }
    }

    newStr = newStr.stringByAppendingString(" ...")

    self.label.text = newStr as String

Idea is: we split words and try check the width while appending from the beginning + the string "..." till we found the a word that will exceed the size, in the case we stop and use this new string
