What is the primary advantage of TextKit 2 over TextKit 1?

TextKit 2 replaces glyph-based logic with a more robust element-based architecture, offering better support for international scripts, thread-safety through value semantics, and improved performance via noncontiguous viewport layout.

Can I use this skill for macOS or visionOS development?

Yes, TextKit 2 is a cross-platform framework for all modern xOS environments, and this skill provides patterns applicable to both UIKit and AppKit implementations.

Does this skill provide code for NSRange to NSTextRange conversion?

Yes, it includes specific API naming heuristics and code snippets for bidirectional conversion between legacy NSRange and modern NSTextRange/NSTextLocation systems.

How do I avoid the TextKit 1 compatibility mode fallback?

The skill details how to properly initialize UITextView or NSTextView using the 'usingTextLayoutManager' flag and how to safely check for textLayoutManager before accessing legacy properties that trigger fallback.
