  • iOS 11+
  • Xcode 10.2+
  • Swift 5
  • CocoaPods 1.7+


Stream Chat SDK consists of two frameworks: StreamChat and StreamChatCore

  • StreamChat — the full SDK library with all UI components. Styling and deep customizations are all supported out of the box.
  • StreamChatCore — low-level library to use Stream Chat APIs. It includes models, presenters, notification manager and HTTP interface.


To integrate StreamChat into your Xcode project using CocoaPods, add this entry in your Podfile:

pod 'StreamChat'

Then run pod install.

If you want to use only StreamChatCore, you can add this entry in your Podfile:

pod 'StreamChatCore'

In any file you'd like to use Stream Chat in, don't forget to import the frameworks:

import StreamChat

or StreamChatCore if you are working with the low-level client:

import StreamChatCore


To integrate Stream Chat into your Xcode project using Carthage, specify it in your Cartfile:

github "GetStream/stream-chat-swift"

Then run: carthage update --platform iOS --new-resolver. This will build frameworks: StreamChatCore.framework and StreamChat.framework into <Path to your Project>/Carthage/Build/iOS/ from where you can add them to your project and link them with your app target. Follow with these steps:

  • Open your Xcode project
  • Select the project in the Navigator
  • Select your app target
  • Open General panel
  • Click the + button in the Linked Franeworks and Libraries section
  • Click the Add Other... and add StreamChatCore.framework in <Path to your Project>/Carthage/Build/iOS/
  • Add StreamChat.framework if you need UI components
  • Open Build Phases panel
  • Click the + button and select New Run Script Phase
  • Set the content to: /usr/local/bin/carthage copy-frameworks
  • Add to Input Files:
    • $(SRCROOT)/Carthage/Build/iOS/StreamChatCore.framework
    • $(SRCROOT)/Carthage/Build/iOS/StreamChat.framework
  • Add to Output Files:
    • $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/StreamChatCore.framework

Now build your app.
