build-ios-apps

Design and implement App Intents, app entities, and App Shortcuts for iOS apps so useful actions and content are available to Shortcuts, Siri, Spotlight, widgets, controls, and other intent-driven system surfaces. Use when exposing app actions outside the UI, adding `AppEntity` and `EntityQuery` types, shaping shortcut phrases and display representations, or routing intent execution back into the main app.

Use XcodeBuildMCP to build, run, launch, and debug the current iOS project on a booted simulator. Trigger when asked to run an iOS app, interact with the simulator UI, inspect on-screen state, capture logs/console output, or diagnose runtime behavior using XcodeBuildMCP tools.

Capture and interpret ETTrace profiles for iOS simulator apps, including symbolicated launch and runtime flamegraphs. Use when asked to profile an iOS app flow, gather simulator performance traces, identify CPU-heavy stacks, compare before/after traces, or produce flamegraph evidence for startup, scrolling, navigation, rendering, or other user-visible latency.

Capture, inspect, compare, and root-cause iOS memory graph leaks using Apple's leaks and memgraph tools. Use when debugging leaked iOS objects, simulator memgraphs, retain-cycle suspicions, memory growth after navigation/logout/account changes, or when asked to prove an iOS leak fix with before/after memgraph evidence.

Implement, review, or improve SwiftUI features using the iOS 26+ Liquid Glass API. Use when asked to adopt Liquid Glass in new SwiftUI UI, refactor an existing feature to Liquid Glass, or review Liquid Glass usage for correctness, performance, and design alignment.
