for Xcode 9 and Swift 4 there's a change we may encounter:

'NSParagraphStyleAttributeName' has been renamed to 'NSAttributedStringKey.paragraphStyle'

Hope this might help you.

Now it's 'NSAttributedString.Key.paragraphStyle'. (Add a "." before "Key").

Is it just me, or is part of the text cut off? After I made that change (thanks, by the way!), the text only goes to "from the surface of Mars. It's" and stops there. This is what code I have 

            let attributedString = NSMutableAttributedString(string: page.story.text)

            let paragraphStyle = NSMutableParagraphStyle()
            paragraphStyle.lineSpacing = 10

            attributedString.addAttribute(NSAttributedStringKey.paragraphStyle, value: paragraphStyle, range: NSMakeRange(0, attributedString.length))

            storyLabel.attributedText = attributedString

Anybody else seeing this? Or will it get resolved in the future videos?

you need to set storyLabel.numberOfLines = 0 after adding it as a subview

Is it just me, after I added the code . Parsan requested as below:

if let page = page { artworkView.image = page.story.artWork

        let attributeString = NSMutableAttributedString(string: page.story.text)
        let paragraphStyle = NSMutableParagraphStyle()
        paragraphStyle.lineSpacing = 10

        attributeString.addAttribute(NSAttributedString.Key.paragraphStyle, value: paragraphStyle, range: NSMakeRange(0, attributeString.length))



        storyLabel.attributedText = attributeString
    }

There is a Green Thread break point 1.1 at paragraphStyle = NSMutableParagraphStyle()
