Bridges.swift.template imports DebugBridgeTouch but no .m/.h template
shipped — consuming apps installing the canonical drop-in would hit a
linker error. Closes that gap with the fixture's verified working code.
Changes:
- New ios-qa/templates/DebugBridgeTouch.{h,m}.template files (carbon
copies of the fixture sources, including the iOS-18+ SwiftUI hit-test
fix verified on iPhone 17 Pro Max).
- Package.swift.template splits into 3 product targets: DebugBridgeCore
(Swift, cross-platform), DebugBridgeUI (Swift, iOS-only), DebugBridgeTouch
(Obj-C, iOS-only). Consuming app adds one dependency on DebugBridgeUI;
Core + Touch come in transitively.
- DebugBridgeTouch sources wrap their body in #if TARGET_OS_IOS so the
cross-platform `swift build` on macOS host doesn't choke on UIKit. On
iOS the real implementation is active; on macOS sendTapAtPoint: is a
no-op returning NO.
- New parity tests pin template ↔ fixture content so future fixture
fixes propagate or fail loudly.
- Restrict swift-build host tests to DebugBridgeCore (the only target
buildable on macOS) and bring up the previously broken XCTest run via
--filter.
Verified post-change: real iPhone 17 Pro Max, iOS 26.5, three /tap
requests against the rebuilt app — counter went 0 → 3, SwiftUI Button
onTap fires every time. Templates now sufficient to ship to any
consuming iOS app.

Closes two layers of the device-control gap:
L1 — Mac daemon's tunnelProvider is now real, not a stub. New files:
- ios-qa/daemon/src/devicectl.ts: thin wrappers around `xcrun devicectl`
(list, info, launch, install, copy-from) with spawn+resolve injection
for unit testability.
- ios-qa/daemon/src/tunnel-bootstrap.ts: orchestrates find-device →
launch-app → resolve IPv6 → wait-for-healthz → copy-boot-token →
POST /auth/rotate → return DeviceTunnel with rotated bearer.
- ios-qa/daemon/test/tunnel-bootstrap.test.ts: 7 tests covering every
error branch (no_devices, no_paired_device, device_locked,
state_server_unreachable, resolve_failed, happy path, explicit-udid).
- index.ts wired to use bootstrapTunnel() when running as CLI; tests
keep using injected stubs.
L2 — In-process touch synthesis for non-UIControl widgets. New target
in the fixture SPM package:
- DebugBridgeTouch (Objective-C): KIF-derived UITouch + IOHIDEvent
synthesis. Loads IOKit dynamically via dlopen/dlsym (IOKit is a
private framework on iOS, can't link statically). Uses iOS 18+
_UIHitTestContext for SwiftUI hit-testing. Public Swift-callable
API: DebugBridgeTouch.sendTap(at:in:). MIT-attributed to
kif-framework/KIF.
- DebugBridgeUI/Bridges.swift: rewritten MutationBridge.handleTap to
delegate to DebugBridgeTouch. ScreenshotBridge + ElementsBridge
implementations also land here.
- FixtureApp/Sources/FixtureApp/FixtureAppApp.swift: wires the bridges
on app launch under #if DEBUG.
Real-iPhone evidence (Conductor sandbox → CoreDevice IPv6 → live app):
- /healthz returns 200 with on-device JSON body
- /screenshot returns 427KB PNG that decodes to your actual phone screen
- Boot-token rotation kills the original token (401 boot_token_invalid
on reuse — the load-bearing security property verified live)
- Session lock + auth gate (401/423/200 paths all work)
- Schema-versioned state envelope (_schema_version + _accessor_hash)
Known partial: synthesized UITouch reaches SwiftUI's host view per
device-side syslog ("non-local connection from fd...:2" earlier showed
the per-connection peer gate working), and HTTP returns 200 ok:true,
but SwiftUI Button onTap handler doesn't fire. UIControl widgets DO
work via UIControl.sendActions. Next step is attaching lldb to the
live app on device to diagnose which validation SwiftUI's gesture
recognizer is failing. The architectural primary path
(`POST /state/<key>` to mutate @Snapshotable fields) is unaffected
and is the recommended control vector.
Documented sources for the KIF-derived synthesis:
- https://github.com/kif-framework/KIF (MIT)
- UITouch-KIFAdditions.m: init flow with _setLocationInWindow:,
setGestureView:, _setIsFirstTouchForView:
- IOHIDEvent+KIF.m: digitizer event construction
- iOS 18+ _UIHitTestContext path for SwiftUI hit-testing
