Check for synchronous work on @MainActor before profiling.\n2. **Only use axiom-performance** if concurrency fixes don't help — Profile after ruling out obvious blocking.\n3. **To pin a specific freeze to app code**, see the Hang Window Workflow in axiom-performance (skills/hang-diagnostics.md) — re-scope `xcprof analyze` to the hang window with `--start-ms/--end-ms --user-binary` to surface the app-owned frame on the main thread.\n\n**concurrency vs axiom-build**: When seeing Swift 6 concurrency errors:\n- **Use concurrency, NOT axiom-build** — Concurrency errors are CODE issues, not environment issues.\n\n**concurrency vs axiom-data**: When concurrency errors involve Core Data or SwiftData:\n- Core Data threading (NSManagedObjectContext thread confinement) → **use axiom-data first**\n- SwiftData + @MainActor ModelContext → **use concurrency**\n- General \"background saves losing data\" → **use axiom-data first**\n- GRDB Sendable patterns (struct records, `databaseSelection` as computed property, Swift 6 conformance) → See axiom-data (skills/grdb-performance.md) §8\n\n## Critical Patterns\n\n**Swift Concurrency** (`skills/swift-concurrency.md`):\n- Progressive journey: single-threaded → async → concurrent → actors\n- @concurrent attribute for forced background execution\n- Isolated conformances, main actor mode\n- 12 copy-paste patterns including delegate value capture, weak self in Tasks\n- Comprehensive decision tree for 7 common error messages\n\n**API Reference** (`skills/swift-concurrency-ref.md`):\n- Actor definition, reentrancy, global actors, nonisolated\n- Sendable patterns, @unchecked Sendable, sending parameter\n- Task/TaskGroup/cancellation, async let, withDiscardingTaskGroup\n- AsyncStream, continuations, buffering policies\n- Isolation patterns (#isolation, @preconcurrency, nonisolated(unsafe))\n- DispatchQueue/DispatchGroup/completion handler migration\n\n**Synchronization** (`skills/synchronization.md`):\n- Mutex (iOS 18+), OSAllocatedUnfairLock (iOS 16+), Atomic types\n- Lock vs actor decision tree\n- Danger patterns: locks across await, semaphores in async context\n\n**Profiling** (`skills/concurrency-profiling.md`):\n- Swift Concurrency Instruments template\n- Diagnosing main thread blocking, actor contention, thread pool exhaustion\n- Safe vs unsafe primitives for cooperative pool\n\n**Runtime Isolation Crashes** (`skills/isolation-inheritance-diag.md`):\n- `_dispatch_assert_queue_fail` and `_swift_task_checkIsolatedSwift` signatures\n- Closure isolation inheritance (Core Data `perform`, Combine `.map`, NotificationCenter `.sink`)\n- Delegate method isolation inheritance (CLLocationManager, NSDocument, AVAudioPlayerDelegate, WKNavigationDelegate)\n- `MainActor.assumeIsolated` misuse\n- Actor reentrancy state staleness\n\n## Automated Scanning\n\n**Concurrency audit** → Launch `concurrency-auditor` agent or `/axiom:audit concurrency` (5-phase semantic audit: maps isolation architecture, detects 8 anti-patterns, reasons about missing concurrency patterns, correlates compound risks, scores Swift 6.4 readiness)\n\n## Anti-Rationalization\n\n| Thought | Reality |\n|---------|---------|\n| \"Just add @MainActor and it'll work\" | @MainActor has isolation inheritance rules. `skills/swift-concurrency.md` covers all patterns. |\n| \"I'll use nonisolated(unsafe) to silence the warning\" | Silencing warnings hides data races. `skills/swift-concurrency.md` shows the safe pattern. |\n| \"It's just one async call\" | Even single async calls have cancellation and isolation implications. |\n| \"I know how actors work\" | Actor reentrancy and isolation rules changed in Swift 6.2. |\n| \"I'll fix the Sendable warnings later\" | Sendable violations cause runtime crashes. Fix them now. |\n| \"My Swift 6 build has zero warnings, so isolation is correct\" | Static checking can't see SDK callbacks. Runtime checks crash anyway. `skills/isolation-inheritance-diag.md`. |\n| \"I'll wrap the crash in `MainActor.assumeIsolated`\" | `assumeIsolated` is a runtime trap, not a silencer. Wrong assumption = crash. |\n| \"Combine is dead, just use async/await\" | Combine has no deprecation notice. Rewriting working pipelines wastes time. See See axiom-uikit (skills/combine-patterns.md). |\n| \"I'll use @unchecked Sendable to silence this\" | You're hiding a data race from the compiler. It will crash in production. |\n| \"This async function runs on a background thread\" | `async` suspends without blocking but resumes on the *same actor*. Use `@concurrent` to force background. |\n\n## Example Invocations\n\nUser: \"I'm getting 'data race' errors in Swift 6\"\n→ Read: `skills/swift-concurrency.md`\n\nUser: \"How do I use @MainActor correctly?\"\n→ Read: `skills/swift-concurrency.md`\n\nUser: \"How do I create a TaskGroup?\"\n→ Read: `skills/swift-concurrency-ref.md`\n\nUser: \"What's the AsyncStream API?\"\n→ Read: `skills/swift-concurrency-ref.md`\n\nUser: \"How do I use assumeIsolated?\"\n→ Read: `skills/assume-isolated.md`\n\nUser: \"Should I use Mutex or actor?\"\n→ Read: `skills/synchronization.md`\n\nUser: \"My async code is slow, how do I profile it?\"\n→ Read: `skills/concurrency-profiling.md`\n\nUser: \"My warning-free Swift 6 build crashes in production with _dispatch_assert_queue_fail\"\n→ Read: `skills/isolation-inheritance-diag.md`\n\nUser: \"Core Data `context.perform` crashes inside an @MainActor view model\"\n→ Read: `skills/isolation-inheritance-diag.md`\n\nUser: \"CLLocationManager delegate method is crashing with _swift_task_checkIsolatedSwift\"\n→ Read: `skills/isolation-inheritance-diag.md`\n\nUser: \"My app is slow due to unnecessary copying\"\n→ See axiom-performance (skills/swift-performance.md)\n\nUser: \"Check my code for Swift 6 concurrency issues\"\n→ Invoke: `concurrency-auditor` agent\n","tagline":"Use when writing ANY async code, actors, threads, or seeing ANY concurrency error.
