Adds the Send files action to the device detail, routing the picked
selection through sendToContact.
Rather than a second picker path, sharePickedFiles now takes a
ShareDestination, so the macOS security-scoped access handling covers both
routes. A contact destination carries no access policy, matching the core's
rule that an offer share is never public.
Device list, detail, and block list under Settings, plus the two sheets:
an incoming offer and a device asking to be remembered. Both are
answer-only, since swiping away would leave the sender waiting.
Accepting an offer routes the released ticket into the ordinary receive
path, so the platform still chooses the destination. The prompt does not
ask a second time; it only falls back to the review sheet when the
destination is unusable.
Drop the Share-diagnostics preference, its Settings toggle and the
DiagnosticsBuildConfig stub. Bug reporting (NoopBugReportService) and the
diagnostics install id used for bug-report correlation are retained.
iOS suspends the process on backgrounding, freezing the core's network
threads so in-flight transfers stall and never fire notifications. Hold a
UIApplication background-task assertion (BackgroundActivityController) while
transfers/shares are active so iOS grants its grace window — long enough to
finish and notify. Released on foreground, on completion, or on expiration.
No UIBackgroundModes added (keeps App Store validation clean); macOS is a
no-op since it already runs unfocused.
Add a localized iOS-only Settings notice explaining the platform limit so it
doesn't read as a bug.
Adds background notifications for the "the thing you were waiting for is
done" moments, alongside the existing incoming-approval-request one:
- a receive finished downloading (receive -> done)
- a receive failed / was interrupted (receive -> failed)
- a share you own failed (send -> failed)
- a receiver finished downloading your share (receiver status completed)
A new TransferNotificationCoordinator observes core state + signals and
publishes these; the decision of which moments notify is a pure function
(plannedTransferNotifications / plannedReceiverNotifications), unit-tested
independently. The first state snapshot only primes existing history as seen
so launch doesn't spam.
Notification permission is now the single source of truth. The in-app
notifications toggle and its decoupled UserDefaults preference are gone;
the Settings section shows an "Allow notifications" button that requests the
OS permission (or deep-links to Settings once decided), and notifications
gate purely on `permission == .granted`.
macOS delivery fixes:
- add a UNUserNotificationCenterDelegate so banners present even while the
app is active (the app window is usually open on macOS)
- present-when-active on macOS, suppress-when-foregrounded on iOS
- reserve the notification id before awaiting publish: the CombineLatest
fired several times and re-added the same identifier, which macOS
coalesces into a silent update with no banner
- LocalNotificationService seeds its permission at init so gating can't
race a not-yet-refreshed .notDetermined
Eight localized title/body strings added (apple-only); the shared
notifications_description copy is generalized from "receive requests" to
"transfer activity".
Add a native SwiftUI VniDrop app (Send/Receive/Settings) talking to the
Rust core via generated UniFFI Swift bindings, plus the uniffi-bindgen
helper crate. iOS uses a TabView, macOS a NavigationSplitView sidebar.
