Yes, working through the NSTextStorage is the way to go. To replace its entire contents you can use -replaceCharactersInRange:withAttributedString: <https://developer.apple.com/documentation/foundation/nsmutableattributedstring/1417045-replacecharactersinrange> with a range that encompasses all current text.
You should not need to manually call -setNeedsDisplay: on the NSTextView as was suggested earlier. If you're working with the right NSTextStorage then its view should observe the changes and automatically mark any redisplay as needed. ~Martin Wierschin > On Feb 02, 2020, at 3:01 PM, Jonathan Prescott via Cocoa-dev > <cocoa-dev@lists.apple.com> wrote: > > Looking at the documentation for NSTextView, it is highly recommended that > you manipulate the NSTextStorage associated with the view.
