Chatto
A lightweight framework to build chat applications, made in Swift
... and provides a placeholder for an input component. Provides support for interactive dismissal of the keyboard and adjusts the insets automatically when it appears. 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.
