The official iOS SDK for Stream Chat
The StreamChatUI SDK is the official iOS SDK for Stream Chat, a service for building chat and messaging applications.
- 4.x is the next major version. The final release is expected to be before 15 August 2021. It's mostly compatible with 3.x, while exposing many more customization options. Beta versions are released on a weekly basis. We recommend using the latest beta for new projects.
- 3.x is the current production version. This version doesn't allow full customizability of the UI elements.
- 2.x is in maintenance mode. We strongly encourage you to plan an upgrade.
The upcoming v4 has a public beta available. If your development timeline fits our release schedule, we strongly encourage you to give it a try and share your feedback with us by opening an issue.
