🎯 Goal

Show how to list the current user's scheduled messages of every channel with ScheduledMessageListController.

📝 Summary

  • A Scheduled tab lists the scheduled messages of every channel, pending ones first and failed ones after, with a badge of the pending ones.
  • Swipe a row to send it now, reschedule it, retry it or delete it, and tap it to edit it in its channel.
  • The composer banner opens the Scheduled tab.

🛠 Implementation

  • DemoScheduledMessageListVC is a SwiftUI list hosted in a UIHostingController, driven by a ScheduledMessageListController.
  • Each row shows the status and the error of the scheduled message, and only offers the actions that apply.

🧪 Manual Testing Notes

  1. Log in to the US East staging app as in the previous PR, and schedule a few messages in different channels.
  2. Open the Scheduled tab: the messages of every channel are listed, and the badge counts the pending ones.
  3. Swipe a row to send it now, reschedule it or delete it. Tap it to edit it in its channel.
  4. Schedule more messages than the app allows in one channel: the row shows the server's error and no Retry.

Summary by CodeRabbit

  • New Features
    • Added a Scheduled Messages tab when scheduled messages are enabled. Its badge counts messages that have not failed and is hidden when there are none.
    • View scheduled and failed messages, with status, conversation details, and message previews. An empty state appears when there are no messages.
    • Open a conversation to edit a message, reschedule or delete it, or send a scheduled message immediately after confirmation.
    • Retry failed messages when the error allows it.
    • Tap the scheduled-messages banner to open the Scheduled Messages tab.

Walkthrough

The demo app now provides a scheduled-message screen in a conditional tab. The screen displays scheduled and failed messages and supports message actions. The tab badge reflects the count of non-failed messages. The composer banner can open the Scheduled tab.

Changes: Scheduled Messages

Layer / File(s) Summary
Scheduled-message list and actions
DemoApp/Screens/ScheduledMessages/DemoScheduledMessageListVC.swift
Adds a scheduled-message list with failed-message grouping, status details, previews, and supported actions. The model performs list operations and reports success or errors.
Tab, badge, and banner integration
DemoApp/Screens/DemoAppTabBarController.swift, DemoApp/StreamChat/DemoAppCoordinator+DemoApp.swift, DemoApp/StreamChat/Components/CustomAttachments/DemoComposerVC.swift
Creates and installs the list screen. The tab appears when scheduled messages are enabled, its badge counts non-failed messages, and the composer banner opens it when the tab controller is available.

Users may be offered a Reschedule action on failed messages that cannot succeed. The change is otherwise mergeable with that known demo-app issue tracked for correction.

Keep the badge and list model on one update path.

When the Scheduled screen loads, DemoScheduledMessageListModel.synchronize() assigns the model to ScheduledMessageListController.delegate. This clears the tab bar’s previous main delegate. The model continues receiving row updates, but DemoAppTabBarController.controller(_:didChangeScheduledMessages:) no longer runs, so the badge remains at its initial value.

Observe the model’s published messages or the controller’s Combine publisher for the badge instead of registering the tab bar as a competing delegate.

Hide the Reschedule action for failed messages.

swipeActions(for:) always adds Reschedule, including when message.status == .failed. The rescheduleMessage documentation in ScheduledMessageListController (Sources/StreamChat/Controllers/ScheduledMessageListController/ScheduledMessageListController.swift:182-234) says a failed scheduled message cannot be changed. The user must delete it and schedule a new one.

A failed row therefore shows an action that cannot succeed. The user picks a date and then gets an error alert, or the controller silently ignores the change. Show Reschedule only when the message is not failed. Failed messages keep Delete and, when retryable, Retry.
