Chatto is a Swift framework to ease the development of chat applications. At the UI level, it takes care of managing the UICollectionView where the messages are displayed and provides a placeholder for an input component.
- Manages UICollectionView, taking care of calculating changes and performing updates.
- Placeholder for an input component at the bottom of the screen.
- Provides support for interactive dismissal of the keyboard and adjusts the insets automatically when it appears.
- Provides a default layout for the UICollectionView.
- Calculates this layout in a background queue (partially if your sizing routines can be only executed in the main thread).
- Triggers notifications to the data source to retrieve more messages (pagination)
- Encourages clean code by decoupling your message's presentation into different presenters
- Decorator
- Diagram of classes (todo)
