SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helps engineers decide when to use TextKit 1 versus TextKit 2 for a text editing stack, reducing migration risk and optimizing feature alignment.

Core Features & Use Cases

  • Provides a decision framework comparing NSLayoutManager (TextKit 1) and NSTextLayoutManager (TextKit 2) across common editor requirements.
  • Guides migration strategy, including dual-path implementations and incremental adoption.
  • Assesses OS version targets, performance implications, and feature availability to produce a recommended approach.

Quick Start

Ask for a recommended layout strategy based on your app’s performance needs and OS targets.

FAQPage Schema
How do I choose between TextKit 1 and TextKit 2 for my iOS text editing stack?▼

Choosing between TextKit 1 and TextKit 2 requires evaluating glyph access, multi-container layouts, Writing Tools, platform OS targets, and migration risk to produce a recommended stack and actionable steps.

What is the best way to migrate from NSLayoutManager to NSTextLayoutManager?▼

The best way to migrate from NSLayoutManager to NSTextLayoutManager involves adopting a dual-path implementation strategy for incremental adoption, reducing migration risk while optimizing feature alignment.

Does TextKit 2 support multi-container layouts and direct glyph access?▼

TextKit 2 support for multi-container layouts and direct glyph access depends on specific feature availability and compatibility, requiring an evaluation against your project's performance needs and OS targets.

When should I not use TextKit 2 for my text layout stack?▼

You should not use TextKit 2 when your app requires specific legacy features like direct glyph access or multi-container layouts that conflict with NSTextLayoutManager compatibility, or when OS targets lack support.

Can I use a dual-path implementation for incremental TextKit 2 migration?▼

Yes, you can use a dual-path implementation for incremental TextKit 2 migration, allowing you to maintain NSLayoutManager while gradually adopting NSTextLayoutManager to manage compatibility and migration risk.
