We have and app that is using UITextView.layoutManager quite a lot. Does that means that in next version of iOS, when TextKit2.0 is available for UITextView, we will have to update the app? Will old, not updated app on AppStore still work without updates?

What are the reasons it is not available on iOS15?

P.S. TextKit1.0 in AppKit have a lot more functionality than UIKit version. Would be great to have feature parity. With ARM CPU in both Macs and iPads there is no reason not to.

TextKit 2 isn't a complete replacement for TextKit 1, and given how many apps rely on TextKit, it's unlikely Apple will drop support for it for a long time. You should be fine.

Also, while I would have liked to see parity between iOS and macOS for TextKit 1, it seems clear that's what TextKit 2 is for, and the legacy APIs won't be unified in the way we might have liked.
