This is the official iOS SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level SDK and a set of reusable UI components.
The StreamChat SDK is a low level client for Stream chat service that doesn't contain any UI components. It is meant to be used when you want to build a fully custom UI. For the majority of use cases though, we recommend using our highly customizable UI SDK's.
The StreamChatUI SDK is our UI SDK for UIKit components. If your application needs to support iOS 13 and below, this is the right UI SDK for you.
The StreamChatSwiftUI SDK is our UI SDK for SwiftUI components. If your application only needs to support iOS 14 and above, this is the right UI SDK for you. This SDK is available in another repository stream-chat-swiftui.
Since the 4.20.0 release, our SDKs can be built using Xcode 14. Currently, there are no known issues on iOS 16. If you spot one, please create a ticket.
layoutMargins, light/dark mode, dynamic font sizes, etc.
UIKitpatterns and paradigms: The API follows the design of native system SDKs. It makes integration with your existing code easy and familiar.
SwiftUIsupport: We have developed a brand new SDK to help you have smoother Stream Chat integration in your SwiftUI apps.
Combine: The StreamChat SDK (Low Level Client) has Combine wrappers to make it really easy use in an app that uses
Stream is free for most side and hobby projects. You can use Stream Chat for free if you have less than five team members and no more than $10,000 in monthly revenue.
Progressive disclosure: The SDK can be used easily with very minimal knowledge of it. As you become more familiar with it, you can dig deeper and start customizing it on all levels.
Highly customizable: Every element is designed to be easily customizable. You can modify the brand color by setting
tintColor, apply appearance changes using custom UI rules, or subclass existing elements and inject them everywhere in the system, no matter how deep is the logic hierarchy.
open by default: Everything is
open unless there's a strong reason for it to not be. This means you can easily modify almost every behavior of the SDK such that it fits your needs.
Good platform citizen: The UI elements behave like good platform citizens. They use existing iOS patterns; their behavior is predictable and matches system UI components; they respect
layourMargins, dynamic font sizes, and other system-defined UI constants.
This SDK tries to keep the list of external dependencies to a minimum. Starting 4.6.0, and in order to improve the developer experience, dependencies are hidden inside our libraries. (Does not apply to StreamChatSwiftUI's dependencies yet).
