Migrate your Chat iOS SDK to Conversations (classic)

(information)

Info

If you are not using >=4.0.0 of our Chat SDK (or later), please follow the appropriate migration guides to get to v4+ before following this guide.

This guide walks you through migrating your Programmable Chat iOS SDK to Conversations (classic). The bulk of the work is renaming entities and refactoring method calls, which this guide covers. You should also review the companion migration guide that covers the high-level changes and new APIs in Conversations (classic).

Rename consumptionHorizon to readHorizon

Update reasons
- TCHChannelUpdateLastConsumedMessageIndex becomes TCHConversationUpdateLastReadMessageIndex
- TCHParticipantUpdateLastConsumedMessageIndex becomes TCHParticipantUpdateLastReadMessageIndex
- TCHParticipantUpdateLastConsumedTimestamp becomes TCHParticipantUpdateLastReadTimestamp
Channel.getUnconsumedMessagesCountWithCompletion becomes Conversation.getUnreadMessagesCountWithCompletion
Member.lastConsumedMessageIndex becomes Participant.lastReadMessageIndex
Member.lastConsumptionTimestamp becomes Participant.lastReadTimestamp
Member.lastConsumptionTimestampAsDate becomes Participant.lastReadTimestampAsDate

Media changes

There are no more streams used to download media. Instead, you'll retrieve a temporary data URL to download it.

SwiftObjective-C

1getMediaContentTemporaryUrl(completion:)
