Produce a complete mobile app architecture design — platform choice, navigation structure, state management, data layer, key screens. Use when asked to "build a mobile app", "new app", "create iOS/Android app", "app architecture", or "cross-platform app".
ios-testing
rusel95/ios-agent-skills
Invoke any time a user is writing iOS/Swift tests or asking why tests behave a certain way — including XCTest versus Swift Testing (@Test/#expect) choices, async ViewModel tests with @Observable or @Published, snapshot testing across device sizes, mocking protocols for dependency injection, setUp/tearDown lifecycle issues, tests that fail on CI but pass locally, flaky async tests, testing VIPER/TCA/MVVM architectures, and coverage gaps on error paths. The trigger is user intent: they are trying to verify, assert, or validate iOS/Swift behavior in a test context, whether they use the word 'testing' or not.
ios-accessibility
rusel95/ios-agent-skills
Production-grade iOS accessibility skill covering VoiceOver, Dynamic Type, color contrast, motion, Switch Control, Voice Control, and WCAG 2.2 compliance for both SwiftUI and UIKit. This skill should be used when creating new iOS screens or views, reviewing existing iOS code for accessibility, adding VoiceOver support, fixing Dynamic Type issues, auditing WCAG compliance, implementing accessibilityLabel/traits/hints, grouping elements for assistive technology, adding custom actions or rotors, respecting system accessibility preferences (reduce motion, increase contrast, differentiate without color), writing accessibility-focused XCTest audits, or preparing apps for enterprise compliance (ADA, EAA, Section 508). Use this skill any time someone is working with iOS accessibility, VoiceOver, Dynamic Type, assistive technology, WCAG mapping, or accessibility modifiers in SwiftUI or UIKit — even if they only say 'make this accessible' or 'add VoiceOver support' or 'check contrast.' Also run an accessibility pass on any newly generated SwiftUI or UIKit view code before finalizing — AI coding assistants systematically produce inaccessible code by default (hardcoded fonts, onTapGesture instead of Button, missing labels, no system preference checks) and this skill corrects those patterns.
