The UITests target stays on 5.0: XCTestCase's nonisolated setUp/init overrides conflict with the target's MainActor default isolation under 6, and test tooling is not shipping code. The original seven diagnostics, plus the layers Swift 6 mode surfaced once those cleared: - SMTPChannel is an actor. It was implicitly MainActor while running its receive loop on a background queue, so parsedLines/lineWaiters/ receiveBuffer were declared main-actor-protected and mutated off it — concurrent mutation while resuming a CheckedContinuation can double-resume, which traps. The actor serialises all state; Network callbacks hop in via Task. The start() continuation also gains an OSAllocatedUnfairLock resume-once guard: the state handler can fire .ready and later .failed, and resuming twice was a pre-existing trap of the same family. - CachedLookupResult is nonisolated (a value pair built inside actor LookupRuntime cannot have a MainActor-bound memberwise init) with conditional Sendable — opting out of MainActor isolation also opted out of the implicit Sendable that globally-isolated types get. - PortScanService.printableBanner is nonisolated: a pure transformation called from the connection's queue. - SweepActivityController stores the activity's Sendable id instead of the non-Sendable Activity, re-resolving via Activity.activities inside each fire-and-forget task, so nothing non-Sendable crosses isolation. - App Intents' static title/description/openAppWhenRun become lets (get-only protocol requirements; static var is shared mutable global state), and the summary helpers are @MainActor to match the model properties they read and the perform() implementations that call them. - ExternalDataService's ISO8601DateFormatter is nonisolated(unsafe), citing Apple's documented thread-safety, rather than risking a parser behaviour change by switching APIs with no test coverage. - TaskMetricsDelegate.metrics is nonisolated(unsafe): written on the session's delegate queue, read only after the request completes, and URLSession guarantees didFinishCollecting precedes task completion. - The share extension extracts the host via async/withCheckedContinuation instead of sending a non-Sendable completion into loadItem's @Sendable handler; Task inherits the view controller's MainActor so the manual DispatchQueue.main hop goes too. Validated: clean Swift 6 build of all product targets, and the full enforced 11-test audit suite green on the floor runtime — Swift 6's runtime isolation checks ran the app through every screen without a trap. 2026-04-20T20:28:12+00:00 Christian Cleberg hello@cleberg.net 2026-04-20T20:28:12+00:00 urn:sha1:ee2520f2c0c2d806fd284c3d6b8a81a3822f5270 - normalize sections and add summary card - fix resolver usage in reverse DNS - include custom port scans in history/export - standardize error handling - decompose ContentView into smaller views 2026-04-04T00:04:08+00:00 Christian Cleberg hello@cleberg.net 2026-04-04T00:04:08+00:00 urn:sha1:21576b75478e2a1ff7a2b189e83bcca97403cce3 2026-04-03T22:14:00+00:00 Christian Cleberg hello@cleberg.net 2026-04-03T22:14:00+00:00 urn:sha1:2c38b5edee339e5fe9060a835d9772a71606dc85 2026-03-18T16:59:38+00:00 Christian Cleberg hello@cleberg.net 2026-03-18T16:59:38+00:00 urn:sha1:376e7b55b4a0c4f54faa0c2828dea4fd17dff288
