A real iOS Xcode app (ios/NucleicRemote) linking the NucleicProtocol SwiftPM library as a local package. Builds for the iOS 27 simulator and launches to the pairing screen. - Transport: NWFrameChannel (NWConnection) + LANDiscovery (Bonjour _nucleic._tcp). - Engine: drives NucleicProtocol.SyncClient (Noise XXpsk0 pair / IK reconnect, hello/welcome, HostMsg→Event stream). - State: RemoteStore (ObservableObject) — the single on-device projection of host state; IdentityStore persists the device identity (Keychain) + pinned host. - UI (UX_IOS): attention-first SessionsView, SessionDetailView (transcript/diff + status-driven action area / composer), ApprovalCardView with Face ID gate on high-risk approvals + allow-always menu, PairingScannerView (AVFoundation QR), SettingsView, connection chip. Same status glyphs/semantics as the Mac. Add-iPhone QR display + server start live on the macOS side (follow-up); push / Live Activity are M5 (needs the relay). gitignore keeps this .xcodeproj despite the blanket *.xcodeproj rule.

NucleicRemote (iPhone client)
The thin iOS remote client for Nucleic (PLAN milestone M4). It's a pure projection of the
Mac host over LAN: monitor sessions, read transcripts/diffs, answer approvals, and send
follow-up input — scope approve. No local git or CLI; the Mac is the single authority
(see docs/UX_IOS.md and docs/SYNC_PROTOCOL.md).
Architecture
All wire/crypto logic is shared with the Mac via the NucleicProtocol SwiftPM library
(this Xcode project links it as a local package at ../..):
- Transport —
NWFrameChannel(NWConnection) +LANDiscovery(Bonjour_nucleic._tcp). - Engine —
NucleicProtocol.SyncClientruns the Noise handshake (XXpsk0 to pair, IK to reconnect), exchanges hello/welcome, and turnsHostMsgs into aSyncClient.Eventstream. - State —
RemoteStore(ObservableObject) is the single on-device UI state, a pure projection of the host. Identity + pinned host live inIdentityStore(Keychain + UserDefaults). - UI — SwiftUI:
SessionsView(attention-first list),SessionDetailView(transcript/diff + status-driven action area),ApprovalCardView(Face ID gate on high-risk),PairingScannerView(QR),SettingsView.
Build & run
# Resolves the local NucleicProtocol package automatically.
xcodebuild -project ios/NucleicRemote/NucleicRemote.xcodeproj \
-scheme NucleicRemote \
-destination 'platform=iOS Simulator,name=iPhone 17 Pro' build
Or open NucleicRemote.xcodeproj in Xcode and run. To pair, start the sync server on the Mac
(Nucleic ▸ Settings ▸ Add iPhone shows the QR), then scan it. On a real device, both must be
on the same Wi‑Fi.
Status
The full pair → list → subscribe → approve → reconnect path is implemented and the protocol/
server side is covered by tests in Tests/NucleicProtocolTests and Tests/NucleicCoreTests.
Push notifications / Live Activity (UX_IOS §5.1/§5.3) are the M5 follow-up (needs the relay).
