# [5.0.0-beta](https://github.com/GetStream/stream-chat-swift/releases/tag/5.0.0-beta)
_March 23, 2026_

### ✅ Added
- First beta v5 release introduces the new `StreamChatCommonUI` module for shared appearance APIs, formatters, resources, and assets used across the SDK UI surface.
- The UI layer has been refreshed with new design tokens, typography, colors, icons, reactions, media badges, and richer file / attachment previews.

### 🔄 Changed
- StreamChat internals were modernized for v5 with Swift 6 complete concurrency checking, broader use of `StreamCore`, and cleanup of collection / controller change-handling internals.
- The package and project structure were reorganized for v5, including buildable folders, updated target membership, and CI / release pipeline changes to match the new module layout.

### ❌ Removed
- Deprecated APIs scheduled for removal in v5 were dropped as part of the release cleanup.
- This keeps the public surface smaller and reduces overlap with the newer APIs introduced and stabilized during the v4 cycle.
- Legacy CocoaPods support and podspecs were removed.
- v5 continues with Swift Package Manager as the supported distribution path for integrating the SDK.
- Legacy SwiftUI wrappers around UIKit components and controller-specific SwiftUI additions were removed in favor of the new v5 UI modularization.
- This simplifies the SDK structure and avoids maintaining parallel abstractions that no longer match the direction of the UI layer.

## StreamChatUI
### ✅ Added

- Add support for jumping to a message which is not in the message list inside Threads [#2566](https://github.com/GetStream/stream-chat-swift/pull/2566)

### 🐞 Fixed
- Fix the message text font when the text accessibility setting is set to large after closing the app [#2575](https://github.com/GetStream/stream-chat-swift/pull/2575)
- Fix the timestamp label being clipped when the text font size is larger [#2575](https://github.com/GetStream/stream-chat-swift/pull/2575)

### ⚠️ Known Issue
When changing the text accessibility while the app is running, it won't affect the message cell text, only after closing the app. So this is a regression of [#2325](https://github.com/GetStream/stream-chat-swift/issues/2325). This regression is necessary, since the original fix did not work 100% as it changed the text font size after closing the app, causing the font to be too big when the text accessibility is set to large. If you still want to have the dynamic font size to be working while the app is running, there is a workaround. You need to return a new `UIFont` instance everytime in `ChatMessageContentView.defaultMessageFont`. Example:
```swift
override var defaultMessageFont: UIFont {
    UIFont.preferredFont(forTextStyle: .body)
}
```
For more details, you can read the documentation of `ChatMessageContentView.defaultMessageFont` or read the PR [#2575](https://github.com/GetStream/stream-chat-swift/pull/2575).

### 🚨 Minor Breaking Changes
Although we don't usually ship breaking changes in minor releases, in some cases where they are minimal and important, we have to do them to keep improving the SDK long-term. Either way, these changes are for advanced customizations which won't affect most of the customers.

- The `ImageCDN` protocol has some minor breaking changes that were needed to support the new Stream CDN v2 and to make it more scalable in the future.
  - `urlRequest(forImage:)` -> `urlRequest(forImageUrl:resize:)`.
  - `cachingKey(forImage:)` -> `cachingKey(forImageUrl:)`.
  - Removed `thumbnail(originalURL:preferreSize:)`. This is now handled by `urlRequest(forImageUrl:resize:)` as well. If your CDN does not support resizing, you can ignore the resize parameter.

# [4.0.0-RC](https://github.com/GetStream/stream-chat-swift/releases/tag/4.0.0-RC)
_September 03, 2021_

### ⚠️ Breaking Changes from `4.0-beta.11`
- JSON Encoding/Decoding for both Network and Database date formatting changed to RFC3339 formats [#1403](https://github.com/GetStream/stream-chat-swift/pull/1403)
- `ChatMessage.threadParticipants` is now an Array instead of Set [#1398](https://github.com/GetStream/stream-chat-swift/pull/1398)
- Introduces `ChatChannelVC` and removes responsibilities of `ChatMessageListVC`. The latter now is only responsible to render the message list layout, the data is provided by `ChatChannelVC` or `ChatThreadVC`. [#1314](https://github.com/GetStream/stream-chat-swift/pull/1314)
- Replaces `ChatMessageActionsVC.Delegate` with `ChatMessageActionsVCDelegate` [#1314](https://github.com/GetStream/stream-chat-swift/pull/1314)
- Renames `ChatChannelListRouter.showMessageList()` -> `showChannel()` [#1314](https://github.com/GetStream/stream-chat-swift/pull/1314)
- Removal of `ComposerVCDelegate` [#1314](https://github.com/GetStream/stream-chat-swift/pull/1314)
- Replaces `ChatMessageListKeyboardObserver` with `ComposerKeyboardHandler` [#1314](https://github.com/GetStream/stream-chat-swift/pull/1314)

#### Understanding `ChatChannelVC` vs `ChatTheadVC` vs `ChatMessageListVC`
- `ChatChannelVC`:
    - `ChatChannelHeaderView`
    - `ChatMessageListVC`
    - `ComposerVC`

- `ChatThreadVC`:
    - `ChatThreadHeaderView`
    - `ChatMessageListVC`
    - `ComposerVC`

A new `ChatChannelVC` is introduced that represents the old `ChatMessageListVC`, which was responsible to display the messages from a channel. The `ChatThreadVC` remains the same and it is responsible for displaying the replies in a thread, but now instead of duplicating the implementation from the channel, both use the `ChatMessageListVC` and configure it for their needs. For this to be possible the `ChatMessageListVC` has now a `ChatMessageListVCDataSource` and `ChatMessageListVCDelegate`. Both `ChatChannelVC` and `ChatThreadVC` implement the `ChatMessageListVCDataSource` and `ChatMessageListVCDelegate`.

- Added `GalleryAttachmentViewInjector.galleryViewAspectRatio` to control the aspect ratio of a gallery inside a message cell [#1300](https://github.com/GetStream/stream-chat-swift/pull/1300)

### 🔄 Changed

# [4.0.0-beta.9](https://github.com/GetStream/stream-chat-swift/releases/tag/4.0.0-beta.9)
_August 05, 2021_

### ⚠️ Breaking Changes from `4.0-beta.8`
- Extra data is now stored on a hashmap and not using the `ExtraData` generic system
- `ChatMessageLayoutOptionsResolver.optionsForMessage` has a new parameter: `appearance` [#1304](https://github.com/GetStream/stream-chat-swift/issues/1304)
- Renamed `Components.navigationTitleView` -> `Components.titleContainerView` [#1294](https://github.com/GetStream/stream-chat-swift/pull/1294)

#### New Extra Data Type

The new `4.0` release changes how `extraData` is stored and uses a simpler hashmap-based solution. This approach does not require creating type aliases for all generic classes such as `ChatClient`.

Example:

```swift
client.connectUser(
    userInfo: .init(
        id: userCredentials.id,
        extraData: ["country": .string("NL")]
    ),
    token: token
)
```

`Message`, `User`, `Channel`, `MessageReaction` models now store `extraData` in a `[String: RawJSON]` container.

```swift
let extraData:[String: RawJSON] = .dictionary([
    "name": .string(testPayload.name),
    "number": .integer(testPayload.number)
])
```

#### Upgrading from ExtraData

If you are using `ExtraData` from `v3` or before `4.0-beta.8` the steps needed to upgrade are the following:

- Remove all type aliases (`typealias ChatUser = _ChatUser<CustomExtraDataTypes.User>`)
- Replace all generic types from `StreamChat` and `StreamChatUI` classes (`__CurrentChatUserController<T>` -> `CurrentChatUserController`) with the non-generic version
- Remove the extra data structs and either use `extraData` directly or (recommended) extend the models
- Update your views to read your custom fields from the `extraData` field

Before:

```swift
struct Birthland: UserExtraData {
    static var defaultValue = Birthland(birthLand: "")
    let birthLand: String
}
```

After:

```swift
extension ChatUser {
    static let birthLandFieldName = "birthLand"
    var birthLand: String {
        guard let v = extraData[ChatUser.birthLandFieldName] else {
            return ""
        }
        guard case let .string(birthLand) = v else {
            return ""
        }
        return birthLand
    }
}
```

# [4.0.0-beta.5](https://github.com/GetStream/stream-chat-swift/releases/tag/4.0.0-beta.5)
_July 07, 2021_

### ⚠️ Breaking Changes from `4.0-beta.4`
- The `ChatSuggestionsViewController` was renamed to `ChatSuggestionsVC` to follow the rest of the codebase. [#1195](https://github.com/GetStream/stream-chat-swift/pull/1195)
- The `CreateChatChannelButton` component was removed. The component acted only as a placeholder and the functionality should be always provided by the hosting app. For an example implementation see the [Demo app](https://github.com/GetStream/stream-chat-swift/blob/main/DemoApp/ChatPresenter.swift).
- The payload of `AnyChatMessageAttachment` changed from `Any` to `Data` [#1248](https://github.com/GetStream/stream-chat-swift/pull/1248).
- The user setting API was updated. It's now required to call one of the available `connect` methods on `ChatClient` after `ChatClient`'s instance is created in order to establish connection and set the current user.

  Migration tips:
  ---
  If you were doing:
  ```
  let client = ChatClient(config: config, tokenProvider: .static(token))
  ```
  Now you should do:
  ```
  let client = ChatClient(config: config)
  client.connectUser(userInfo: .init(id: userId), token: token)
  ```
  ---
  Guest users before:
  ```
  let client = ChatClient(
    config: config,
    tokenProvider: .guest(
      userId: userId,
      name: userName
    )
  )
  ```
  Now you should do:
  ```
  let client = ChatClient(config: config)
  client.connectGuestUser(userInfo: .init(id: userId))
  ```
  ---
  Anonymous users before:
  ```
  let client = ChatClient(config: config, tokenProvider: .anonymous)
  ```
  Now you should do:
  ```
  let client = ChatClient(config: config)
  client.connectAnonymousUser()
  ```
  ---
  If you use tokens that expire you probably do something like this:
  ```
  let client = ChatClient(
    config: config,
    tokenProvider: .closure { client, completion in
      service.fetchToken { token in
        completion(token)
      }
    }
  )
  ```
  Now you should do:
  ```
  let client = ChatClient(config: config)
  service.fetchToken { token in
    client.connectUser(userInfo: .init(id: userId), token: token)
  }
  // `tokenProvider` property is used to reobtain a new token in case if the current one is expired
  client.tokenProvider = { completion in
    service.fetchToken { token in
      completion(token)
    }
  }
  ```

### 🐞 Fixed
- `ConnectionController` fires its `controllerDidChangeConnectionStatus` method only when the connection status actually changes [#1207](https://github.com/GetStream/stream-chat-swift/issues/1207)
- Fix cancelled ephemeral (giphy) messages and deleted messages are visible in threads [#1238](https://github.com/GetStream/stream-chat-swift/issues/1238)

# [3.0](https://github.com/GetStream/stream-chat-swift/releases/tag/3.0)
_January 22nd, 2021_

## StreamChat SDK reaches another milestone with version 3.0 🎉

### New features:

* **Offline support**: Browse channels and send messages while offline.
* **First-class support for `SwiftUI` and `Combine`**: Built-it wrappers make using the SDK with the latest Apple frameworks a seamless experience.
* **Uses `UIKit` patterns and paradigms:** The API follows the design of native system SDKs. It makes integration with your existing code easy and familiar.
* Currently, 3.0 version is available only using CocoaPods. We will add support for SPM soon.

To use the new version of the framework, add to your `Podfile`:
```ruby
pod 'StreamChat', '~> 3.0'
```

### ⚠️ Breaking Changes ⚠️

In order to provide new features like offline support and `SwiftUI` wrappers, we had to make notable breaking changes to the public API of the SDKs.

**Please don't upgrade to version `3.0` before you get familiar with the changes and their impact on your codebase.**

To prevent CocoaPods from updating `StreamChat` to version 3, you can explicitly pin the SDKs to versions `2.x` in your `podfile`:
```ruby
pod 'StreamChat', '~> 2.0'
pod 'StreamChatCore', '~> 2.0' # if needed
pod 'StreamChatClient', '~> 2.0' # if needed
```

The framework naming and overall structure were changed. Since version 3.0, Stream Chat iOS SDK consists of:

#### `StreamChat` framework

Contains low-level logic and is meant to be used by users who want to build a fully custom UI. It covers functionality previously provided by `StreamChatCore` and `StreamChatClient`.

#### `StreamChat UI` framework _(currently in public beta)_

Contains a complete set of ready-to-use configurable UI elements that you can customize a use for building your own chat UI. It covers functionality previously provided by `StreamChat`.

### Sample App

The best way to explore the SDKs and their usage is our [sample app](https://github.com/GetStream/stream-chat-swift/tree/main/Sample). It contains an example implementation of a simple IRC-style chat app using the following patterns:

* `UIKit` using delegates
* `UIKit` using reactive patterns and SDK's built-in `Combine` wrappers.
* `SwiftUI` using the SDK's built-in `ObservableObject` wrappers.
* Learn more about the sample app at its own [README](https://github.com/GetStream/stream-chat-swift/tree/main/Sample).
