From b4fe5106488cbadb970243bf50079f7a88e231ce Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sun, 17 May 2026 20:12:03 -0700 Subject: [PATCH] test(ios): real Swift compile + XCTest fixture; device-path probe; loopback bind fix MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the gap from prior commits where E2E tests stubbed the Swift StateServer in TypeScript. Now there's a real SwiftPM fixture at test/fixtures/ios-qa/FixtureApp/ that compiles the production templates and runs an XCTest suite against the actual StateServer implementation. Three new test layers: - swift build invariants (periodic-tier): debug-config build succeeds, XCTest suite passes (validates real Swift impl over Foundation + Network), release-config build has zero DebugBridge symbols (structural #if DEBUG gate works end-to-end). - Real-device probe (periodic-tier, GSTACK_HAS_IOS_DEVICE=1): devicectl can list + pair the connected iPhone. Surfaces actionable instructions when the trust dialog hasn't been confirmed yet. - Fixture sources copied from ios-qa/templates/ — Package.swift splits the bridge into DebugBridgeCore (Foundation+Network, cross-platform) and DebugBridgeUI (UIKit/SwiftUI, iOS-only) so swift build can validate the bulk of the production code on macOS without an iPhone or simulator. Also fixes a real bug the XCTest unit suite caught: NWListener with requiredLocalEndpoint on params silently fails to bind for listening (it's an outbound-connection concept). Replaced with .requiredInterfaceType=.loopback + .acceptLocalOnly=true + a per-connection peer-address check. The fork's inherited code had this bug; we shipped it untouched in v1.41.0.0 and the new XCTest suite caught it immediately. --- ios-qa/templates/StateServer.swift.template | 33 +- test/fixtures/ios-qa/FixtureApp/.gitignore | 6 + test/fixtures/ios-qa/FixtureApp/Package.swift | 41 ++ .../DebugBridgeCore/DebugBridgeManager.swift | 46 ++ .../Sources/DebugBridgeCore/StateServer.swift | 550 ++++++++++++++++++ .../Sources/DebugBridgeUI/DebugOverlay.swift | 137 +++++ .../Sources/FixtureApp/FixtureAppState.swift | 36 ++ .../StateServerSmokeTests.swift | 107 ++++ test/helpers/touchfiles.ts | 12 + test/skill-e2e-ios-device.test.ts | 172 ++++++ test/skill-e2e-ios-swift-build.test.ts | 108 ++++ 11 files changed, 1246 insertions(+), 2 deletions(-) create mode 100644 test/fixtures/ios-qa/FixtureApp/.gitignore create mode 100644 test/fixtures/ios-qa/FixtureApp/Package.swift create mode 100644 test/fixtures/ios-qa/FixtureApp/Sources/DebugBridgeCore/DebugBridgeManager.swift create mode 100644 test/fixtures/ios-qa/FixtureApp/Sources/DebugBridgeCore/StateServer.swift create mode 100644 test/fixtures/ios-qa/FixtureApp/Sources/DebugBridgeUI/DebugOverlay.swift create mode 100644 test/fixtures/ios-qa/FixtureApp/Sources/FixtureApp/FixtureAppState.swift create mode 100644 test/fixtures/ios-qa/FixtureApp/Tests/DebugBridgeCoreTests/StateServerSmokeTests.swift create mode 100644 test/skill-e2e-ios-device.test.ts create mode 100644 test/skill-e2e-ios-swift-build.test.ts diff --git a/ios-qa/templates/StateServer.swift.template b/ios-qa/templates/StateServer.swift.template index ac7a3128f..8cafac6bb 100644 --- a/ios-qa/templates/StateServer.swift.template +++ b/ios-qa/templates/StateServer.swift.template @@ -134,20 +134,36 @@ public final class StateServer { private func startListener(family: AddressFamily) { do { + // Loopback-only binding: requiredInterfaceType=.loopback restricts the + // listener to lo0.
