How to set kerning in iPhone UILabel

Question

I am developing an iPhone app, and I want to set kerning in UILabel. The code I\'ve written (possibly around kCTKernAttributeName) seems to be in error. How mig

In Swift 2.0...

Add an extension:

extension UIView {
    func attributes(font: String, color: UIColor, fontSize: CGFloat, kern: Double) -> [String: NSObject] {
        let attribute = [
            NSForegroundColorAttributeName: color,
            NSKernAttributeName: kern,
            NSFontAttributeName : UIFont(name: font, size: fontSize)!
        ]
        return attribute
    }
}

Now, just set your UILabel as attributedText:

self.label.attributedText = NSMutableAttributedString(string: "SwiftExample", attributes: attributes("SourceSans-Regular", color: UIColor.whiteColor(), fontSize: 20, kern: 2.0))   

Obviously, I added a bunch of parameters that you may not need. Play around -- feel free to rewrite the method -- I was looking for this on a bunch of different answers so figured I'd post the whole extension in case it helps someone out there... -rab
