Adds the native SwiftUI Saved Devices experience on top of the production saved-device core, as a top-level destination in the iOS tab bar and the macOS sidebar. Core seam: - App-facing saved-device domain models mirroring core/SavedDeviceModels.kt, with lifecycle helpers (canReceive/canResume/canCancel/canDelete) so views never hand-roll state checks. - 21 gateway methods through CoreGateway/CoreRepository with UniFFI mapping. cancelTargetedTransfer, forgetSavedDevice and blockDevice run off the serial lane: each must reach the core while a targeted receive is blocking it. - Payload-free pairingChanged/targetedTransferChanged signals, dispatched before the numeric-transferId guard since saved-device events identify their subject by peer endpoint or a string transfer id. Experience: - Screen lists saved devices and outstanding consent requests only; the global targeted-transfer history stays out, reachable per device. - Details as a sheet with detents on compact layouts and a native inspector on macOS, owning Send, label, forget/block and that device's transfers. - Label editing is transactional: the draft and editor survive a failed write, conflicting actions are refused while saving, and the editor closes only after the core confirms. - Pairing and targeted-offer consent hosted at the app root, answerable from any tab and suppressed while a transfer approval is up. Dismissing a pairing prompt suppresses locally without consuming the single-use eligibility; dismissing an offer declines it, since an unanswered offer holds a slot in the core's bounded per-sender queue. - Targeted send reuses the invitation composer's affordances with file, folder, rename, replace and cleanup parity. Picker copies are released on replace/remove/clear/cancel and after a successful create, but kept after a failure so retry does not require re-picking. - Notifications for pairing requests and offers (withdrawn once answered) and for terminal targeted transfers. Wording follows direction: on the sending device the peer finished receiving, not us. Localization: - Widens 52 saved-device keys from kmp-only to both platforms. - Five keys carried a literal %1$s with no declared args, which Compose renders positionally but the Apple generator emits as a plain constant, leaking the placeholder into the UI. They now use named args; Compose output is byte-identical. - Adds targeted_offer_title/body. Reusing the invitation approval copy stated the roles backwards, announcing the sender as the receiver. Also surfaces core startup failures: the startup overlay is drawn above the snackbar host, so a failed initialize() was indistinguishable from an app that never finished loading. AppModel now keeps the reason, logs it, and the overlay shows it with a retry, plus the technical detail in DEBUG builds. Send and receive between two devices is verified only partially; a missing endpoint-identity credential currently blocks startup on the test device.
VniDrop — native Apple app (iOS / iPadOS / macOS)
A native SwiftUI app for Apple platforms, sharing the existing Rust transfer core
(crates/vnidrop) through UniFFI-generated Swift bindings. The Rust crate is not
modified; the Kotlin/Compose app layer is ported to Swift and mirrors the Compose
UI screen-for-screen. Android, Windows, and Linux continue to use shared/ + Compose.

Build & run
Prerequisites: Xcode, Rust with the Apple targets
(aarch64-apple-ios, aarch64-apple-ios-sim, x86_64-apple-ios,
aarch64-apple-darwin), and xcodegen (brew install xcodegen).
# From the repository root:
make apple-core # Rust core, Swift bindings, and XCFramework
make apple-project # generate apple/VniDrop.xcodeproj
make open-apple-project # generate and open the project in Xcode
make build-apple-macos # unsigned macOS build (App Store target)
make open-apple # build and launch the macOS app
make build-apple-ios # unsigned iOS simulator app
make check-apple # iOS simulator tests
make apple-project also generates ignored Store and Direct version xcconfig
files. Their CURRENT_PROJECT_VERSION values come from the central version
resolver as UTC YYYYMMDD.HHMM.SS build identifiers. Regenerate the project
before creating another App Store archive so it receives a fresh build number;
direct DMG builds refresh their own value automatically.
macOS shipping channels
The macOS app ships through two targets that build identical sources:
VniDrop(Release) — Mac App Store / TestFlight. Sandboxed, no self-updater.VniDropDirect(Release-Direct) — direct-download.dmgon GitHub Releases + Homebrew cask. Adds the Sparkle auto-updater behind theDIRECT_DISTRIBUTIONcompile flag, so the App Store binary never links Sparkle.
make build-apple-macos-direct # unsigned compile-check of the direct target
make build-apple-dmg # signed (+ notarized) .dmg
Full signing, notarization, appcast, and cask flow: see
RELEASE-MACOS.md.
Use APPLE_PROFILE=release to request a release Rust core, or set
APPLE_DESTINATION to override the automatically selected iOS simulator.
Code signing is disabled for the app and test targets; local and CI builds do
not require an Apple Development team or provisioning profile. Make builds can
opt in with APPLE_CODE_SIGNING=YES. For signed builds from Xcode, create the
ignored apple/Local.xcconfig and override the signing settings there, including
the development team.
Typecheck & tests
The Xcode project is the only build definition: it owns the UI, its package
dependencies, and the VniDropTests bundle (module VniDrop, which is what the
tests import). Everything runs through xcodebuild:
make check-apple # iOS simulator unit tests
make build-apple-macos # unsigned macOS build (typecheck)
There is deliberately no SwiftPM manifest for the app. A second build definition
would duplicate the target's package dependencies, and the previous one had
already drifted out of sync with project.yml badly enough that neither
swift build nor swift test worked.
Generated / ignored artifacts
build-core.sh produces build outputs that are gitignored (see apple/.gitignore):
VnidropCore/vnidrop.xcframework/, VnidropCore/Sources/VnidropCore/Vnidrop.swift,
and .build-core/. A clean checkout must run build-core.sh before generating or
opening the Xcode project. VniDrop.xcodeproj itself is generated by XcodeGen from
project.yml and does not need to be committed.
Build profile note
The default is debug. The workspace [profile.release] uses thin LTO, which the
current macOS toolchain miscompiles into corrupt host proc-macro dylibs
("mis-aligned LINKEDIT string pool"). build-core.sh sets
CARGO_PROFILE_DEV_STRIP=none (matching the existing Gobley Xcode run-script) so
debug builds succeed. For a release core, disable LTO for proc-macros/build
scripts (e.g. add a [profile.release.build-override] lto = false locally) — the
Rust crate itself is never changed.
System frameworks
The Rust core (iroh network stack) links SystemConfiguration, Security, and
libresolv. These are declared in project.yml for the app target.
Parity & scope
Screens mirror the Compose UI in shared/. Two deliberate simplifications:
- Empty-state Lottie animations are rendered as SF Symbols (no
lottie-iosdependency); swap inlottie-iosif exact-parity animation is required. - Bug reporting is stubbed behind
BugReportService(NoopBugReportService) and a real transport lands in a later phase. There is no telemetry or crash auto-reporting.
