feat(mobile): share into Buzz from the iOS share sheet by brow · Pull Request #9433 · block/buzz

brow · 2026-11-13T00:43:57Z

Lets people share screenshots, screen recordings, photos, URLs and text from any iOS app into Buzz. Today Buzz doesn't appear in the share sheet at all.

Plain Buzz icon: opens a new Solo chat with the items in its composer.
Suggested conversation: iOS offers channels and DMs the person recently sent top-level messages in. Choosing one opens that conversation with the items in its composer. When the conversation is already open, the share goes to that page's composer instead of opening a second one; if another page covers it, Buzz stays where it is and shows "Go back to that conversation to finish sharing", and the items join the draft when the person goes back.
The share extension has no UI and sends nothing. It copies the items into the app group and opens Buzz, which prefills the normal composer, so drafts, attachments, mentions and failed-send handling all stay the app's (see the ADR).
If the conversation already has a draft, Buzz asks whether to add the shared items to it or replace it.
A share to a conversation that's no longer available (a removed community or channel, or an unreadable share) shows "That conversation isn't available". A share while signed out shows "Sign in to share".

Suggestions come from an outgoing INSendMessageIntent the app donates after a top-level send or a new Solo chat. The notification extension no longer donates incoming messages, so receiving a message never makes a conversation a suggestion; it still turns the push into a communication notification with the sender's avatar. Both use the same conversation identifier, now the plain community and channel IDs instead of a hash, because the extension needs to hand the identifier back to the app.

Regressions

Nothing changes for people who never use the share sheet, except that sending a top-level message or starting a Solo chat now makes one local INInteraction.donate call (skipped while the age restriction is on, which still purges every interaction).
Communication notifications look the same. Dropping the incoming donation removes work (and a deletion fence) from the notification extension's time budget.
The share hand-off reuses the existing deep link dispatcher. A share link is a new link type; notification and message links take the same paths as before.

Validation

Added tests:
- Dispatcher hand-off: a share to a suggested channel opens it with the shared text and files; shares to a removed community, an unlisted channel, an unknown manifest version or a missing manifest show the error and delete the pending share; share links accept only the extension's UUID ids.
- Composer delivery: with an existing draft, Add appends the shared text on a new line and attaches the file, Replace clears the draft first, and the app group copy is deleted either way.
- Notification presenter: specializes the notification from the intent, or falls back to the ordinary content when that throws (replaces the donation and deletion-fence tests).
Full mobile Flutter suite and BuzzPushKit Swift tests pass.
Automated app run on an iPhone 17 Pro simulator (iOS 27, dev relay test community), recorded above: sent a DM, shared a photo from Photos with the Buzz icon from a cold start (new Solo chat with the photo attached), then handed a link and photo to a DM that had a draft and chose Add. Also checked that a share's pending files are deleted after delivery.
Limitation: the iOS simulator never shows share-sheet conversation suggestions (it has no coreduetd), so the suggested-DM step in the video is staged by writing the same pending share and link the extension writes. Choosing a real suggestion still needs a check on a device.
Known gaps, all confined to sharing: suggestions have no avatar image yet; a suggestion for a conversation left after signing out shows "isn't available"; choosing Later in the unfinished-chat dialog keeps the share until the next new chat; and a pending share the app never receives (for example when Buzz doesn't open) stays in the app group.

Before merge

On a real iPhone, choose a suggested conversation in the share sheet and confirm the shared items open in that conversation's composer (the simulator can't show suggestions). Waived before merge: the managed test iPhone shows no share-sheet suggestions for any app, so this will be checked on a personal phone after landing.

Adds an iOS share extension that hands shared photos, videos, URLs and text to the app, which prefills the chosen conversation's composer. Conversations a person sends top-level messages in are donated as share-sheet suggestions; the plain Buzz icon opens a new Solo chat. The notification extension stops donating incoming interactions.

A share whose files can't be copied still adds its text to the composer and shows an error for the files. A suggestion donation that completes after an age restriction took effect requests the age gate's durable interaction cleanup. Signed-off-by: Tom Brow <[email protected]>

The send paths read the active community before awaiting the send, so a send that finishes after navigation no longer reads a disposed ref. Notifications keep grouping under the hashed conversation key they were already delivered with; only the intent's conversation identifier carries the plain IDs. The share delivery test waits on the pending share's deletion instead of fixed sleeps. Signed-off-by: Tom Brow <[email protected]>

A share whose files can't be copied and that has no text now shows the file error without offering Add or Replace, so Replace can no longer clear an existing draft and add nothing. Signed-off-by: Tom Brow <[email protected]>

A share to a conversation whose page is already open now returns to that page instead of pushing a second one, so one composer owns the draft and its attachments. It walks out through nested navigators such as Home's conversation pane, pops covering pages the way Back would, and stops at a page that refuses to close; the share still goes to the open composer. Signed-off-by: Tom Brow <[email protected]>

…sation Returning to an open conversation by popping the pages over it could discard another page's unsent draft or work. A share to a conversation that is already open now never closes anything: its composer takes the share once it is on screen, and when another page covers it, a toast says to go back to that conversation to finish sharing. Signed-off-by: Tom Brow <[email protected]>

A second share for a conversation that hadn't taken the first one yet replaced it and deleted its items. Shares now wait in order, and the composer offers each in turn. Signed-off-by: Tom Brow <[email protected]>

The share extension counts items it couldn't load or copy in the manifest, and the composer reports them alongside whatever did arrive. Signed-off-by: Tom Brow <[email protected]>

[P2] Keep one owner for the open Solo draft

When a New chat composer already contains a caption and photo, another plain-icon share pushes a second composer with the same new-solo key. The new page restores the caption but not the photo, because attachments remain owned by the covered composer. Could this reuse the existing draft route, or allocate a separate draft key when starting an independent chat?

…igned (#9489) iOS release builds of main fail at export with "No profiles for `xyz.block.buzz.dogfood.mobile.ShareExtension` were found" ([buzz-mobile-releases build 62](https://buildkite.com/cash/buzz-mobile-releases/builds/62)). [#9433 iOS share sheet](#9433) added a ShareExtension target, and the release signing setup has no app ID or provisioning profile for it yet. This unhooks the ShareExtension target from the Xcode project (target, embed step and build settings) so the app builds and signs as it did before #9433. Nothing else changes: - The extension's sources stay in `mobile/ios/ShareExtension/`, so restoring it once the profiles exist is a revert of this commit. - The app's share hand-off code and outgoing share suggestions stay. Without the extension, Buzz just doesn't appear in the share sheet, as before #9433, and the hand-off never runs. ### Regressions - Sharing into Buzz from the iOS share sheet goes away until the profiles are registered. That's the point of this PR. - The app still donates `INSendMessageIntent` after a send. iOS only shows those as share suggestions for an app whose share extension declares the intent, so they stay invisible until the extension returns. ### Validation - iOS simulator debug build of the app succeeds with the target removed. - No other target referenced ShareExtension (it had no target dependencies). - Automated full-app run skipped: this only removes a build target, and the app code is unchanged.
