Research: Text Engine Evaluation

Question

Which text rendering and editing engine should the editor use on Apple platforms?

Options Evaluated

TextKit 2

• Native Apple framework, first-class SwiftUI support
• Handles complex text layout (RTL, CJK, emoji)
• Active development by Apple

Custom Engine

• Full control over rendering pipeline
• Higher maintenance burden
• Risk of platform inconsistencies

Conclusion

TextKit 2. The native framework covers all requirements, integrates cleanly with the platform, and avoids the maintenance cost of a custom engine.
