How do I append text to the begging of a NSTextView instance?










0














In my macOS app, there's a NSTextView showing some logs. When a log is generated, I use NSTextView.textStorage.append(NSAttributedString) to add it to the end of the view with a new line character.



(1) I'm not sure know how to add a log to the beginning of the view.



(2) I feel each log should be a seperate element instead of a string with a new line character, should I use other ways to build this log view ?



class LogView: NSTextView 

func log(text: String)
DispatchQueue.main.async
self.textStorage?.append(NSAttributedString(string: "(text)n", attributes: [NSAttributedStringKey.foregroundColor: NSColor.white]))
