iOS Code Review
Arguments
--parallel: Spawn specialized subagents per technology areaHard gates
Complete in order before writing Issues in the output (empty scope is allowed; fabricated findings are not).
1. Scope gate: You have an explicit list of .swift paths under review (from Step 1 or a user-provided path). Pass: List captured in working notes or one line: No Swift files in scope β then stop with no Issues.
2. Linter gate (style): Step 2 commands ran for this tree; if no .swiftlint.yml / .swiftlint.yaml, note that in one line. Pass: You do not report a style issue that SwiftLint would already enforce for that line when config exists and swiftlint succeeds.
3. Protocol gate: beagle-ios:review-verification-protocol is loaded before Step 6. Pass: If you report any Issues, at least one finding was checked against that checklist (name the item in Review Summary or on that Issue); if you report zero Issues, state Protocol applied; no issues in Review Summary.
4. Evidence gate (Critical/Major): For each Critical or Major item, you re-read the file at FILE:LINE (full surrounding context, not only the diff hunk). Pass: The Issue text matches observable code at that location.
Do not begin Step 6 until Gates 1β3 are satisfied (skills load order stays Steps 4β5).
Step 1: Identify Changed Files
git diff --name-only $(git merge-base HEAD main)..HEAD | grep -E '\.swift$'
Step 2: Verify Linter Status
CRITICAL: Run SwiftLint BEFORE flagging any style issues.
# Check if SwiftLint config exists and run it
if [ -f ".swiftlint.yml" ] || [ -f ".swiftlint.yaml" ]; then
swiftlint lint --quiet
fi
Rules:
Step 3: Detect Technologies
# SwiftUI (always with swift files that import it)
grep -r "import SwiftUI" --include="*.swift" -l | head -3SwiftData
grep -r "import SwiftData\|@Model\|@Query" --include="*.swift" -l | head -3Swift Testing
grep -r "import Testing\|@Test\|#expect" --include="*.swift" -l | head -3Combine
grep -r "import Combine\|AnyPublisher\|@Published" --include="*.swift" -l | head -3URLSession (explicit async patterns)
grep -r "URLSession\.shared\|\.data(from:\|\.download(from:" --include="*.swift" -l | head -3CloudKit
grep -r "import CloudKit\|CKContainer\|CKRecord" --include="*.swift" -l | head -3WidgetKit
grep -r "import WidgetKit\|TimelineProvider\|WidgetFamily" --include="*.swift" -l | head -3App Intents
grep -r "import AppIntents\|@AppIntent\|AppEntity" --include="*.swift" -l | head -3HealthKit
grep -r "import HealthKit\|HKHealthStore\|HKQuery" --include="*.swift" -l | head -3WatchKit
grep -r "import WatchKit\|WKExtension\|WKInterfaceController" --include="*.swift" -l | head -3Animations (beyond basic withAnimation)
grep -r "PhaseAnimator\|KeyframeAnimator\|matchedGeometryEffect\|navigationTransition\|scrollTransition\|CABasicAnimation\|CASpringAnimation\|CAKeyframeAnimation\|UIViewPropertyAnimator\|UIDynamicAnimator\|\.symbolEffect\|\.contentTransition\|CustomAnimation\|MeshGradient" --include="*.swift" -l | head -3
Step 4: Load Verification Protocol
Load beagle-ios:review-verification-protocol skill and keep its checklist in mind throughout the review.
Step 5: Load Skills
Use the Skill tool to load each applicable skill (e.g., Skill(skill: "beagle-ios:swift-code-review")).
Always load:
beagle-ios:swift-code-reviewbeagle-ios:swiftui-code-reviewConditionally load based on detection:
| Condition | Skill |
|-----------|-------|
| SwiftData detected | beagle-ios:swiftdata-code-review |
| Swift Testing detected | beagle-ios:swift-testing-code-review |
| Combine detected | beagle-ios:combine-code-review |
| URLSession detected | beagle-ios:urlsession-code-review |
| CloudKit detected | beagle-ios:cloudkit-code-review |
| WidgetKit detected | beagle-ios:widgetkit-code-review |
| App Intents detected | beagle-ios:app-intents-code-review |
| HealthKit detected | beagle-ios:healthkit-code-review |
| WatchKit detected | beagle-ios:watchos-code-review |
| Animation code detected | beagle-ios:ios-animation-code-review |
Step 6: Review
Sequential (default): 1. Load applicable skills 2. Review Swift quality issues first (concurrency, memory, error handling) 3. Review SwiftUI patterns (view composition, state management, accessibility) 4. Review detected technology areas 5. Consolidate findings
Parallel (--parallel flag):
1. Detect all technologies upfront
2. Spawn one subagent per technology area with Task tool
3. Each agent loads its skill and reviews its domain
4. Wait for all agents
5. Consolidate findings
Before Flagging Issues
1. Check SwiftLint output - don't duplicate linter findings 2. Check code comments for intentional patterns (// MARK:, // NOTE:, etc.) 3. Consider Apple framework idioms - what looks wrong generically may be correct for the framework 4. Trace async code paths before claiming missing error handling or race conditions
Step 7: Verify Findings
Before reporting any issue: 1. Re-read the actual code (not just diff context) 2. For "unused" claims - did you search all references? 3. For "missing" claims - did you check framework/parent handling? 4. For syntax issues - did you verify against current version docs? 5. Remove any findings that are style preferences, not actual issues
Step 8: Review Convergence
Single-Pass Completeness
You MUST report ALL issues across ALL categories (style, logic, types, tests, security, performance) in a single review pass. Do not hold back issues for later rounds.
Before submitting findings, ask yourself:
If yes to either: include those anticipated downstream issues NOW, in this review, so the author can address everything at once.
Scope Rules
Fix Complexity Budget
Fixes to existing code should be flagged at their real severity regardless of size.
However, requests for net-new code that didn't exist before the diff must be classified as Informational:
These are improvement suggestions for the author to consider in future work, not review blockers.
Iteration Policy
If this is a re-review after fixes were applied:
Output Format
## Review Summary[1-2 sentence overview of findings]
Issues
Critical (Blocking)
1. [FILE:LINE] ISSUE_TITLE
- Issue: Description of what's wrong
- Why: Why this matters (crash, data loss, security, race condition)
- Fix: Specific recommended fix
Major (Should Fix)
2. [FILE:LINE] ISSUE_TITLE
- Issue: ...
- Why: ...
- Fix: ...
Minor (Nice to Have)
N. [FILE:LINE] ISSUE_TITLE
- Issue: ...
- Why: ...
- Fix: ...
Informational (For Awareness)
N. [FILE:LINE] SUGGESTION_TITLE
- Suggestion: ...
- Rationale: ...
Good Patterns
[FILE:LINE] Pattern description (preserve this) Verdict
Ready: Yes | No | With fixes 1-N (Critical/Major only; Minor items are acceptable)
Rationale: [1-2 sentences]
Post-Fix Verification
After fixes are applied, run:
# Swift build and lint
swift build
swiftlint lint --quietRun tests if present
swift test
All checks must pass before approval.
