The safe, verifiable slice of iOS multi-host: switch which paired Mac the phone views, reusing the
existing (proven) single-connection reconnect — no rewrite of the connection state machine. The
simultaneous [HostID: HostConnection] multiplexer stays deferred (it needs two real Macs to verify).
RemoteStore: an `activeHostID` (the paired Mac the flat projection reflects); `hostChoices` (paired
registry live, mock hosts in demo); `switchHost(to:)` — live re-points via reconnect(), demo swaps
the mock host preserving in-demo edits; `reconnect()`/`pair()` set the active host; `unpair()` now
forgets the *active* Mac and switches to a remaining one if any (identical for a single host). Demo
seeds two mock Macs ("Andrew's Mac", "Studio Mac") with distinct sessions/dashboards.
SessionsView: a host-switcher menu in the toolbar, shown only when >1 Mac.
Verified in the iOS Simulator (demo mode): the switcher lists both Macs, and switching swaps the
whole session projection + the tab badge (screenshots taken). Single-host behavior is unchanged
(one host ⇒ switcher hidden ⇒ flat state exactly as before).

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).
