Question 1

How do I handle keyboard appearance with ChatLayout?

Accepted Answer

ChatLayout does not provide keyboard handling; you must update UICollectionView's contentInsets manually or use a library like InputBarAccessoryView, as shown in the example app. This gives full control but requires extra implementation.

Question 2

ChatLayout vs MessageKit: which is better for my project?

Accepted Answer

Choose ChatLayout for maximum customization and control over layout and animations; opt for MessageKit if you want an all-in-one solution with pre-built components and faster setup, but less flexibility.

Question 3

Does ChatLayout support UICollectionViewDiffableDataSource?

Accepted Answer

Yes, ChatLayout can process updates from UICollectionViewDiffableDataSource, but you need to ensure correct command handling, as mentioned in the Todo section, to avoid animation issues.

Question 4

How to implement sticky headers in ChatLayout?

Accepted Answer

ChatLayout supports pinned cells that behave like headers/footers; use the provided APIs to configure sticky cells, and refer to the documentation for implementation details.

Question 5

What causes strange animations in ChatLayout and how to fix them?

Accepted Answer

Issues often stem from incorrect delete/insert commands in data updates; use diffing libraries like DifferenceKit carefully and debug commands in ChatLayout.prepare method, as advised in the README.

Question 6

Can I use ChatLayout with Texture for better performance?

Accepted Answer

Yes, but it requires manual implementation of ChatLayoutDelegate to propagate node sizes, since Texture's default wrapper is hardcoded for UICollectionViewFlowLayout, as noted in the README.
