App Store upload with the iOS 26 SDK rejects the NDEF value (error 90778
"NDEF is disallowed") and requires TAG. NFCNDEFReaderSession keeps working
under the TAG entitlement, so no code changes are needed.
- Info.plist: drop unused `fetch`/`processing` background modes (no
BGTaskScheduler implementation exists, which they would require); keep
remote-notification.
- Info.plist: set ITSAppUsesNonExemptEncryption=false — the app's standard
end-to-end encryption qualifies for the mass-market export exemption, so no
compliance code is required.
- project.yml: emit dwarf-with-dsym for Release so archive symbol upload works.
The remaining upload errors (NFC "NDEF is disallowed", Unsupported SDK) are
artifacts of building with a beta Xcode/SDK 27 and clear when archiving with a
release/RC Xcode; NFCNDEFReaderSession legitimately requires the NDEF format
entitlement, so it is kept as-is.
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.
