Best practices and example-driven guidance for building SwiftUI views and components, including navigation hierarchies, custom view modifiers, and responsive layouts with stacks and grids. Use when creating or refactoring SwiftUI UI, designing tab architecture with TabView, composing screens with VStack/HStack, managing @State or @Binding, building declarative iOS interfaces, or needing component-specific patterns and examples.
Fact lookup: Apple Human Interface Guidelines corpus (greppable markdown). Query on demand for accessibility and ergonomic minimums (hit-target sizes, Dynamic Type), platform terminology, system component capabilities, and App-Review-relevant conventions. Not design direction.
Start here for any iOS or SwiftUI task. Coordinates best-practice guides, correctness checks, and full Apple API references. Use before navigating to other Apple skills — for building, reviewing, refactoring, or debugging iOS apps.
Refactor and review SwiftUI view files with strong defaults for small dedicated subviews, MV-over-MVVM data flow, stable view trees, explicit dependency injection, and correct Observation usage. Use when cleaning up a SwiftUI view, splitting long bodies, removing inline actions or side effects, reducing computed `some View` helpers, or standardizing `@Observable` and view model initialization patterns.
UX and visual design consultant for iOS apps using Apple's Liquid Glass design system (iOS 26+). Use when asking about element positioning, layout decisions, visual hierarchy, or whether a design choice is "Apple-approved." Provides design rationale and guidance—not code. Helps create Apple Design Award-worthy apps.
Production-grade SwiftUI with Apple Design Award-quality aesthetics. Use when building visually striking iOS interfaces — screens, components, redesigns. Screenshot-driven visual iteration, Liquid Glass (iOS 26+), bold design direction. For design advice without code, use ios-design-consultant instead.

Comprehensive reference for writing reliable XCUITest UI tests in Swift 6.
// Basic test structure
@MainActor
final class MyUITests: XCTestCase {
var app: XCUIApplication!
override func setUp() {
super.setUp()
continueAfterFailure = false
app = XCUIApplication()
app.launch()
}
func testExample() {
let button = app.buttons["Submit"]
XCTAssertTrue(button.waitForExistence(timeout: 5))
button.tap()
}
}

.md files first.SKILL.md frontmatter, then grep their local files. This is faster and uses less context than fetching new docs from the internet.sosumi.ai Markdown mirror. For example, /documentation/xcuiautomation/xcuielement maps to https://sosumi.ai/documentation/xcuiautomation/xcuielement.
