Proposed changes

Adds @expo/ui (SDK 57) and renders List.Container on iOS with a SwiftUI List (inset grouped), through ListContainer.ios.tsx.

  • List.Section, List.Item, List.Radio, List.Checkbox and list pickers render as native SwiftUI sections and rows when they sit directly in an iOS List.Container. Titles use Dynamic Type text styles, single-value preference rows use a native menu Picker, and separators and insets come from the native list style.
  • Rows that are not list pieces are hosted through RNHostView, sized to the row width reported by SwiftUI.
  • The iOS sidebar (SidebarView/index.ios.tsx) is a native sidebar list with selection for the current stack and the Admin panel.
  • Contact, room and user rows (New message, Select users, Room members, Add existing channel, Select list, Picker, Directory items, Share list) use NativeListRow on iOS.
  • Status: the Clear after option is a native menu picker inside the list on iOS.
  • Virtualized lists (rooms list, messages, directory results) are untouched.

Android keeps its existing layout. Language, Default browser and Status views keep their FlatList on Android and branch to List.Container only on iOS. The Android sidebar rows share useStackItems with iOS but render as before.

The Directory filter options use a plain View instead of List.Container: they sit in an action sheet that sizes itself to its content, and a SwiftUI List has no intrinsic height.

https://rocketchat.atlassian.net/browse/NATIVE-1561

How to test or reproduce

On iOS:

  1. Open the sidebar. Check Profile, status, Chats, Profile, Accessibility, Settings and Admin panel rows, and that the current screen is selected. Voice call is disabled during an active call.
  2. Open Settings. Tap Security and privacy, toggle Log analytics events, go back. Open Legal, go back.
  3. Settings, Language: switch language and confirm the app reloads with the new language.
  4. Settings, Default browser: select a browser, go back and reopen, confirm it is kept.
  5. Settings, Media auto download: change Images to another value from the menu.
  6. Accessibility and appearance: change Theme to Dark and back to Light; change Display preferences; increase Dynamic Type and confirm row text scales.
  7. Preferences: change "Also send thread message to channel" from the menu. Notification preferences: change a value.
  8. Open a room, Actions, Notifications: change a value. Check the call rows in Actions.
  9. Edit status: pick each status, set Clear after from the menu, save.
  10. New message: open, start a DM, create a channel. Select users when creating a group. Room members list.
  11. Team: Add existing channel, select and add a channel.
  12. Directory: tap the filter icon, check Channels, Users and Teams, select Users, open a result.
  13. Share extension list and Push troubleshoot screens render their sections.

On Android:

  1. Repeat steps 1, 3, 4 and 9. Language and Default browser show the full-width radio list with separators and bottom padding, Status shows the input, radio list, Clear after row and Save button scrolling together.
  2. Spot-check steps 2, 5, 7, 10 and 12 look unchanged.

Further comments

List, DirectoryItem and NewMessageView item snapshots changed because Jest resolves the .ios.tsx files. The rows are still in the snapshots, now wrapped in Expo UI host views.

* fix(a11y): close drawer when navigating to the focused sidebar route

Tapping a sidebar entry for the route already focused left the drawer
open, because the drawer router only closes it when the focused index
changes. Subsequent taps were swallowed by the drawer scrim.

* chore(e2e): map ToastsAndDialogs flow to SidebarView

The flow reaches Accessibility & appearance through the sidebar, so a
change under app/views/SidebarView can break it. Without this the
impact analysis never selects its shard for sidebar-only changes.

Walkthrough

The iOS list container now renders inset-grouped rows and sections. New native row components support directory, contact, channel, picker, and selection views. A new iOS sidebar renders profile, status, route, and admin sections based on navigation and app state.

Changes

iOS Lists and Sidebar

Layer / File(s) Summary
Render inset-grouped list content
package.json, app/containers/List/ListContainer.ios.tsx, app/containers/List/ListSection.tsx
Adds @expo/ui and updates the iOS list container to flatten children, render rows and sections, and provide native-list context. ListSection.children now accepts any ReactNode.
Build and adopt native list rows
app/containers/NativeListRow/*, app/containers/DirectoryItem/*, app/containers/UserItem*, app/views/AddExistingChannelView/*, app/views/DirectoryView/index.tsx, app/views/NewMessageView/*, app/views/PickerView/*, app/views/RoomMembersView/index.tsx, app/views/SelectListView/*, app/views/SelectedUsersView/index.tsx, app/views/ShareListView/index.tsx
Adds NativeListRow, themed separators, and iOS row implementations. List views pass row-position and background data, and use the new separators. Media-call handling moves to useStartMediaCall; related tests are updated.
Adapt list context and list-based views
app/containers/List/NativeListContext.ts, app/containers/List/ListItem.tsx, app/containers/List/ListSeparator.tsx, app/views/SidebarView/components/Profile.tsx, app/views/DirectoryView/Options.tsx, app/views/DefaultBrowserView/index.tsx, app/views/LanguageView/index.tsx
List items and profile headers use transparent backgrounds inside native lists, and separators return null. Directory options use a View wrapper. Browser and language choices use list sections instead of FlatList.
Build sidebar sections and route items
app/views/SidebarView/index.ios.tsx, app/views/SidebarView/components/*
Adds the iOS sidebar, which tracks the active route and conditionally renders status, route, and admin sections. Extracted hooks provide visibility and permission state.
Update SelectListView test mapping
.sniffler/test-map.json
Changes two test dependency globs from the SelectListView.tsx path to SelectListView/**.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Suggested labels: type: feature

Merge Risk: 🟡 Moderate · up to 9ea00

On iOS, larger text settings leave native row text unscaled, while some list spacing and sidebar separators differ from the previous layout. Address the text-scaling issue before merging.

26-29: 🎯 Functional Correctness

The inspected callers pass only children and optional testID. No current caller passes style, contentContainerStyle, or scroll callbacks. The iOS implementation is new in the PR, so no existing iOS caller is shown to break. The narrower interface may limit future callers, but that potential does not establish a current issue.

Add explicit return types to the new functions.

Annotate the returns of hasLeftIcon, insetSeparators, and ListSection. As per coding guidelines, “add explicit type annotations to function parameters and return types.”

Preserve the separator’s existing style.

If a caller supplies <List.Separator style={...} />, this clone replaces that style with the inset style. The caller’s styling no longer appears on iOS. Compose the existing style with the computed inset instead of replacing it. ListSeparator accepts a style prop, and cloneElement gives the replacement prop precedence. (raw.githubusercontent.com)
