iOS Development Expert
Comprehensive guidance for iOS app development. This skill aggregates specialized modules for different aspects of iOS development.
When This Skill Activates
Use this skill when the user:
- Asks about iOS development best practices
- Wants code review for iOS/Swift projects
- Needs UI/UX review against Human Interface Guidelines
- Wants accessibility audit for iOS apps
- Is planning a new iOS app
- Needs help with SwiftUI patterns for iOS
- Asks about navigation architecture (NavigationStack, NavigationSplitView, TabView)
- Wants to run/launch the app in the Simulator or screenshot it to verify a change
Available Modules
Read relevant module files based on the user's needs:
coding-best-practices/
Swift code quality and modern idioms for iOS.
- Modern Swift patterns and idioms
- Architecture patterns (MVVM, Clean Architecture)
- Code quality standards
- Performance optimization
ui-review/
UI/UX review against Apple HIG.
- Human Interface Guidelines compliance
- Font usage and Dynamic Type support
- Accessibility review (VoiceOver, color contrast)
- SwiftUI best practices for iOS/watchOS
accessibility-audit/
Structured accessibility audit workflow (advisory).
- Automated XCUITest audits (
performAccessibilityAudit) + CI patterns
- Accessibility Inspector workflow
- Manual VoiceOver / Voice Control / Dynamic Type passes per common task
- App Store Accessibility Nutrition Label evaluation + declaration
navigation-patterns/
SwiftUI navigation architecture patterns.
- NavigationStack, NavigationLink, navigationDestination
- NavigationSplitView (two/three column, iPad/macOS)
- TabView (iOS 18 customizable tabs, sidebar mode)
- Programmatic navigation (NavigationPath, pop-to-root, state restoration)
- Navigation transitions (zoom, custom animations)
app-planner/
iOS app planning and analysis.
- New app concept to architecture
- Existing app audits
- Tech stack evaluation
- Product planning guidance
run-simulator/
Build, install, launch, and screenshot the app in the Simulator to verify a
change visually (operational — uses Bash, not just guidance).
- Discover scheme + an available simulator (no hardcoded device names)
- Build for the simulator and resolve the
.app + bundle id
- Boot, install, launch, then screenshot and read it back
- Drive navigation / deep links to reach the changed screen
run-device/
Run an app on a physical iPhone/iPad from the CLI (no Xcode GUI).
- Build + code-sign for a device with
xcodebuild -allowProvisioningUpdates
- Install and launch via
devicectl
- Screenshot on hardware via
libimobiledevice
- Device prerequisites (Developer Mode, pairing) and signing gotchas
How to Use
- Identify user's need from their question
- Read relevant module files from subdirectories
- Apply the guidance to their specific context
- Reference Apple HIG documentation when needed
Example Workflow
User asks for UI review:
- Read
ui-review/SKILL.md for the full review process
- Check their SwiftUI code against HIG
- Verify accessibility compliance
- Report findings with specific recommendations
