Do not use it for Swift Concurrency scheduling, SwiftUI rendering, app launch, or profiling workflows unless the question is specifically about Swift runtime costs.\n---\n\n# Swift Runtime Performance\n\n## Purpose\n\nUse this skill to review Swift code for runtime-level performance costs without turning every abstraction into a problem. Focus on concrete costs such as allocation, ARC traffic, dispatch, specialization, copying, optimizer visibility, and unsafe memory boundaries.\n\nThis skill should help the agent distinguish real hot-path runtime costs from theoretical micro-optimizations.\n\n## When to use this skill\n\nUse this skill when the task involves Swift runtime behavior such as:\n\n- heap allocation, stack vs heap storage, object layout, boxed values, or closure contexts;\n- ARC retain/release traffic, ownership, lifetime, weak/unowned references, or closure captures;\n- direct dispatch, class dispatch, Objective-C dispatch, witness dispatch, or dynamic dispatch in hot paths;\n- `any Protocol`, `some Protocol`, generics, type erasure, specialization, or unspecialized hot code;\n- copy-on-write collections, large values, custom COW storage, or repeated copies;\n- optimized SIL inspection, compiler optimization, inlining, devirtualization, or specialization evidence;\n- unsafe Swift, pointer lifetime, memory binding, aliasing, buffer mutation, or safe wrappers around unsafe regions;\n- module boundaries that affect optimizer visibility, `@inlinable`, `@usableFromInline`, `@frozen`, or public API resilience trade-offs.\n\n## When not to use this skill\n\nDo not use this skill for:\n\n- general Swift syntax or API usage questions with no runtime performance concern;\n- app launch investigations where the main issue is pre-main, dyld, static initializers, SDK startup, first frame, or first interaction;\n- SwiftUI performance issues where the main issue is identity, invalidation, state scope, layout, drawing, animation, or scrolling;\n- Swift Concurrency issues where the main issue is task lifetime, actor isolation, MainActor responsiveness, cancellation, AsyncSequence cleanup, reentrancy, or executor behavior;\n- profiling workflow questions where the main task is choosing tools, interpreting traces, designing signposts, XCTest metrics, MetricKit, or production signals;\n- broad architecture questions unless there is a specific runtime cost in a hot path.\n\nIf another skill is more specific, route there first and use this skill only for the runtime subproblem.\n\n## Neighbor skill boundaries\n\nUse these boundaries before applying runtime advice:\n\n- Use `swift-concurrency-performance` when the task centers on actors, tasks, MainActor, cancellation, AsyncSequence, continuations, task groups, executor behavior, or responsiveness under async work.\n- Use `ios-launch-performance` when the task centers on cold launch, warm launch, pre-main, dyld, framework loading, static initializers, AppDelegate, SwiftUI `App`, first frame, first interaction, or launch metrics.\n- Use `swiftui-performance` when the task centers on SwiftUI body evaluation, invalidation, identity, state ownership, dependency scope, `List`, `LazyVStack`, layout, drawing, animation, or lifecycle work in views.\n- Use `ios-performance-profiling` when the task centers on choosing Instruments templates, interpreting traces, XCTest metrics, MetricKit, signposts, memory graphs, hangs, hitches, CPU, allocations, disk I/O, networking, or production telemetry.\n- Use this skill when a neighboring task reveals a Swift runtime-level cost such as allocation churn, ARC traffic, existential boxing, witness dispatch, unspecialized generics, repeated COW copies, or unsafe memory boundaries.\n\n## Core principle\n\nDo not optimize based only on how the source code looks.\n\nFirst identify:\n\n1. whether the code is on a hot path;\n2. what runtime cost is suspected;\n3. whether the cost is visible in measurement, compiler output, or a small benchmark;\n4. whether the proposed change preserves semantics and improves the measured path;\n5. what trade-off the change introduces.\n\nA runtime optimization is useful only when it reduces cost in a path that matters.\n\n## Runtime cost taxonomy\n\nClassify the suspected issue before recommending a change.\n\nUse these categories:\n\n- **Allocation** — heap objects, boxes, closure contexts, existential containers, temporary objects, intermediate collections.\n- **ARC** — retain/release traffic, closure captures, weak/unowned access, bridged object lifetime, reference-backed value storage.\n- **Dispatch** — dynamic dispatch, witness dispatch, Objective-C dispatch, closure calls, missed devirtualization.\n- **Existentials and generics** — `any`, `some`, type erasure, generic specialization, unspecialized hot paths, boxing.\n- **Copying** — COW storage, large values, repeated collection mutation, defensive copies, bridging copies.\n- **Compiler optimization** — inlining, specialization, devirtualization, module visibility, resilience boundaries, optimized SIL output.\n- **Unsafe boundary** — pointer lifetime, binding, alignment, aliasing, mutation, escaping buffers, safe wrappers.\n- **Module boundary** — public API visibility, `@inlinable`, `@usableFromInline`, `@frozen`, ABI resilience, optimizer visibility.\n\n## Core workflow\n\n1. **Locate the user-visible symptom.** Identify whether the concern is latency, scrolling, repeated work, memory growth, CPU use, binary size, launch impact, or theoretical code review risk.\n2. **Confirm the hot path.** Ask whether the code runs frequently, touches many elements, blocks interaction, runs during startup, or appears in measurements.\n3. **Classify the suspected cost.** Use the runtime cost taxonomy instead of saying the code is vaguely “slow.”\n4. **Look for evidence.** Prefer Instruments, Allocations, Time Profiler, optimized SIL, benchmark output, XCTest performance tests, or production signals.\n5. **Separate semantics from mechanics.** Do not remove an abstraction only because it has a possible cost. Check what design purpose it serves.\n6. **Propose the smallest safe change.** Prefer local changes that reduce allocation, ARC traffic, dispatch, copying, or missed specialization without damaging API clarity.\n7. **Explain trade-offs.** Mention readability, API flexibility, testability, binary size, ABI stability, build time, or maintenance cost.\n8. **Validate the result.** Do not call the optimization successful without a before/after validation path.\n\n## Decision rules\n\n### If the code is not on a hot path\n\nAvoid low-level rewrites.\n\nExplain that the concern may be theoretically valid but unlikely to matter without evidence. Suggest measurement only if the path is suspected to affect user-visible performance.\n\n### If the issue is allocation\n\nCheck whether allocation comes from:\n\n- class instances;\n- closure contexts;\n- boxed variables;\n- existential storage;\n- type erasure wrappers;\n- intermediate arrays, dictionaries, sets, strings, or data buffers;\n- bridging between Swift and Objective-C/Foundation types.\n\nPrefer reducing repeated allocation over replacing every reference type.\n\n### If the issue is ARC\n\nCheck ownership and lifetime before recommending changes.\n\nLook for repeated retain/release traffic in loops, closure captures of large owners, unnecessary weak access in hot paths, and reference-backed value storage. Do not treat `weak` and `unowned` as performance fixes. They are ownership tools first.\n\n### If the issue is dispatch\n\nAsk whether dynamic dispatch is intentional.\n\nPrefer `final` for app-level classes that are not designed for inheritance. Use generics, concrete types, or internal implementation details only when they preserve the intended abstraction and matter in the measured path.\n\nDo not flatten useful polymorphism without evidence.\n\n### If the issue is `any Protocol`\n\nAsk whether runtime heterogeneity is required.\n\n`any Protocol` is not automatically wrong. It is appropriate when values of different concrete types must be stored or passed uniformly. Consider generics or opaque types when the hot path can remain statically typed.\n\n### If the issue is generics\n\nCheck whether specialization actually happens.\n\nGenerics help most when the optimizer can see enough implementation detail to specialize the hot path. Module boundaries, public resilience, large functions, or type erasure can limit that.\n\n### If the issue is copy-on-write\n\nCheck mutation patterns and uniqueness boundaries.\n\nRepeated mutation of COW values can be cheap when storage is uniquely referenced and expensive when it repeatedly copies. Custom COW must preserve value semantics and document thread-safety assumptions.\n\n### If the issue is SIL or compiler output\n\nUse optimized SIL, not Debug SIL, for performance conclusions.\n\nLook for evidence such as allocation instructions, retain/release traffic, witness dispatch, existential opening, closure creation, missed specialization, and missed devirtualization. Treat SIL as evidence, not as an excuse to overfit source code to one compiler version.\n\n### If the issue is unsafe Swift\n\nDo not recommend unsafe code as a first step.\n\nUse unsafe APIs only when safe APIs cannot express the operation efficiently enough, measurement shows the abstraction cost matters, and the unsafe region can be kept small behind a safe wrapper.\n\n### If the issue is module boundaries\n\nSeparate runtime optimization from architecture and build-time concerns.\n\nUse `@inlinable`, `@usableFromInline`, and `@frozen` only when the API commitment is acceptable. These attributes are not generic “make it faster” switches.\n\n## Common gotchas\n\n- `struct` does not guarantee stack allocation.\n- `class` does not automatically mean a performance bug.\n- Value semantics can still involve heap storage and ARC.\n- `Array`, `String`, `Dictionary`, `Set`, and `Data` can hide reference-backed storage.\n- `any Protocol` is a useful abstraction with runtime cost, not a mistake.\n- `some Protocol` is not a universal replacement for `any Protocol`.\n- Generics help most when specialization happens.\n- `final` is a good default for app-level classes that are not designed for inheritance, but it should not be oversold as a standalone performance fix.\n- `@inline(__always)` can increase code size and should not be the first fix.\n- `@inlinable` is an API and ABI commitment.\n- `weak` and `unowned` are ownership tools, not performance tools.\n- Debug-build behavior is not reliable evidence for optimized runtime performance.\n- Unsafe code can be slower, less optimizable, or incorrect if used casually.\n- Do not replace readable architecture with low-level code unless the measured path justifies it.\n\n## Reference routing\n\nRead references selectively. Do not load all reference files by default.\n\n- `references/allocation-and-layout.md` — read when the task involves stack vs heap behavior, object layout, closure boxes, existential storage, temporary allocations, or hidden heap storage inside value types.\n- `references/arc-and-ownership.md` — read when the task involves retain/release traffic, closure captures, weak/unowned references, object lifetime, reference cycles, COW ownership, or bridging lifetime.\n- `references/dispatch-and-specialization.md` — read when the task involves direct dispatch, class dispatch, Objective-C dispatch, witness dispatch, closure dispatch, devirtualization, inlining, or generic specialization.\n- `references/existentials-generics-opaque-types.md` — read when the task involves `any Protocol`, `some Protocol`, generics, type erasure, protocol witness dispatch, opaque result types, or replacing existential-heavy hot paths.\n- `references","tagline":"Use this skill when reviewing Swift code for runtime-level performance costs, including heap allocation, ARC traffic, stack vs heap storage, closure capture contexts, method dispatch, protocol witness dispatch, existentials vs generics, opaque types, copy-on-write, SIL optimizer ","category":"research","tags":["agent-skill"],"author":"Livsy90","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"Livsy90/iOS-Performance-Agent-Skills","creatorName":"Livsy90","creatorUrl":"https://github.com/Livsy90","sourceUrl":"https://github.com/Livsy90/iOS-Performance-Agent-Skills/tree/main/swift-runtime-performance","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/livsy90-swift-runtime-performance#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
