Swift Development

Announce: "I'm using the swift-dev skill. Following the 4-phase workflow."

MANDATORY: Read and Follow the Shared Workflow

You MUST read workflow.md NOW and follow ALL 4 phases defined there. The sections below provide Swift-specific inputs for each phase.

Read patterns.md during Phase 1.

If you lost workflow.md from context: Re-read ../../shared/workflow.md NOW before continuing.

Swift-Specific Configuration

Verification Commands (Phase 1 plan + Phase 3 verify)

WORKFLOW STATE Verification line: swift build, swift test, swiftlint

Phase 3 Tier A — SPM projects:

swift build — compilation
swift test — tests
swiftlint — linting (if configured)
Coverage target: 70-80%

Phase 3 Tier C — Xcode projects:

xcodebuild build or xcodebuild test
SwiftUI: xcodebuild build -scheme [scheme] -destination 'platform=iOS Simulator,name=iPhone 16'

Implementation Rules (Phase 3)

Model structure — Structs with Codable CRUD variants per entity (CreateRequest/UpdateRequest/Response), domain-driven file organization, composition over deep inheritance, prefer structs over classes
Minimize complexity — lazy sequences for large collections, Dictionary lookups over array scans
Preserve compatibility — CodingKeys for renamed fields, default values for new properties, preserve public API signatures, @available for deprecations

Staff Review Configuration (Phase 4)

Patterns file path: Path to this skill's patterns.md

Swift-Specific Rules

The compiler catches type errors, not logic bugs or architectural problems — verification is still mandatory
SwiftUI previews only prove the view compiles — run swift test for real verification
No positive claim without running swift test or swift build

Quality Checklist (Swift-Specific)

Add these to the shared workflow's verification checklist:

Using Swift 5.9+ / Swift 6 features where appropriate
Structs preferred over classes (value semantics by default)
Protocol-oriented design used
async/await for asynchronous code
No force unwraps outside tests
Proper error handling with typed throws or do/catch
swift build succeeds without warnings
swift test passes (or xcodebuild test)
swiftlint passes (if configured)
