Question 3

Can it help me troubleshoot TextKit 1 fallback issues?

Accepted Answer

Absolutely. The skill includes specific debugging strategies for identifying when a UITextView or NSTextView has automatically reverted to TextKit 1, along with heuristics to prevent this expensive one-way operation.

Question 4

When should I use this skill in my development workflow?

Accepted Answer

Use this skill when migrating legacy TextKit 1 code to the modern TextKit 2 system, implementing custom text styling, or integrating iOS 18+ Writing Tools. It is especially useful for avoiding the 'Compatibility Mode' fallback that can degrade app performance.

Question 5

How does this skill handle international text and complex scripts?

Accepted Answer

The skill provides patterns for object-based ranges (NSTextLocation/NSTextRange) that replace legacy glyph-based APIs. This ensures your app correctly handles bidirectional text and complex scripts like Arabic or Kannada where character-to-glyph mapping isn't 1:1.
