问题 I can't believe I am asking this question but (been looking for the answer for an hour and a half with no luck)... how do I append NSAttributedText to a UITextView? (in Swift 2.0+) I'm building a tool which downloads items from my server, and as they come in I want to add AttributedText with green for success or red color for fails.
