Swift 4 Label attributes

Question

I\'m moving from swift 3 to swift 4. I have UILabels that I am giving very specific text properties to the label. I\'m getting an \'unexpectedly found nil while unwrapping

Answer 1

In Swift 4.x, this should look like :

        let strokeTextAttributes: [NSAttributedStringKey: Any] = [
        NSStrokeColorAttributeName: UIColor.black,
        NSForegroundColorAttributeName : UIColor.white,
        NSStrokeWidthAttributeName : -2.0,
        NSFontAttributeName : UIFont.boldSystemFont(ofSize: 18)
    ]
