TextKit is a sophisticated Apple framework for text storage,
layout, and editing in macOS programs. It dates back to NextStep
and it has an Objective-C implementation that is bridged to Swift.
I am writing a custom NSTextStorage implementation in Swift. Now
and then I worry that I am focusing my development on an aged API
when something easier and more powerful will emerge, soon.
Is there a new text API that I should be paying attention to, now?
Any reason to believe that TextKit will be outmoded any time soon?
