Very basic implementation of enabling hyphenation for text.

String+Hyphenation.swift

import UIKit

public extension String {
	/// Transforms this string into an NSAttributedString that has hyphenation enabled.
	/// Especially at larger preferredContentSizes, regular word wrapping can lead to really
	/// choppy line breaks. Hyphenating allows fuller use of the line whenever possible,
	/// resulting in more text on the screen.
	/// - Returns: An NSAttributedString version of this String with hyphenation enabled
	func withHyphenationEnabled() -> NSAttributedString {
		let paragraphStyle = NSMutableParagraphStyle()
		paragraphStyle.hyphenationFactor = 1.0
		return NSAttributedString(string: self, attributes: [.paragraphStyle: paragraphStyle])
	}
}
