| description | Search and inspect local iOS 26 SDK documentation and Swift interfaces, especially SwiftUI and SwiftUICore. Use when Codex needs current iOS 26 SwiftUI APIs, Liquid Glass components, view modifiers, availability, signatures, deprecations, symbol docs, or SDK-only facts and should not rely on memory or public web docs being available. |
Search iOS 26 Docs
Use the local Xcode iPhone Simulator SDK as the source of truth for iOS 26 APIs. Prefer this skill before web search when the task asks what is available in the current SDK, how a SwiftUI symbol is declared, what availability it has, or whether an iOS 26 API exists.
Quick Start
Build or refresh the cached symbol graphs:
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/build_cache.py"
Search SwiftUI and SwiftUICore symbol docs:
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/search_symbols.py glass button style
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/search_symbols.py backgroundExtensionEffect --ios26
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/search_symbols.py toolbar spacer --module SwiftUI --limit 12
Probe a symbol or concept with exact SDK source snippets attached:
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/probe_symbol.py" ZoomNavigationTransition --module SwiftUI
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/search_symbols.py" VNRecognizeTextRequest --module Vision --verify-interfaces --limit 12
Discover SDK modules before deciding where to search:
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/search_symbols.py" --find-module vision
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/search_symbols.py" --list-modules
The search script auto-builds the default cache on first use. Use --force on build_cache.py when Xcode changes or search results look stale.
Workflow
- Resolve the active SDK with
xcrun --sdk iphonesimulator --show-sdk-path.
- Use
scripts/search_symbols.py for prose docs, symbol names, declarations, and availability. This reads cached swift-symbolgraph-extract output from the local SDK.
- Add
--verify-interfaces or use scripts/probe_symbol.py when exact compiler declarations, overloads, underscored symbols, generated attributes, or platform availability matter. Verification searches .swiftinterface, headers, and apinotes and reports source snippets plus diagnostics.
- Use
--find-module PATTERN or --list-modules to discover candidate SDK modules, then rerun with explicit --module values.
- Cite findings as local SDK facts. If a symbol is not found in symbol graphs, check
sourceOnlyMatches from --verify-interfaces before concluding it does not exist.
Interface Inspection
Swift interfaces are API surfaces, not full documentation. They are still the best fallback for exact signatures and attributes:
SDK_PATH=$(xcrun --sdk iphonesimulator --show-sdk-path)
SWIFTUI="$SDK_PATH/System/Library/Frameworks/SwiftUI.framework/Modules/SwiftUI.swiftmodule/arm64-apple-ios-simulator.swiftinterface"
SWIFTUICORE="$SDK_PATH/System/Library/Frameworks/SwiftUICore.framework/Modules/SwiftUICore.swiftmodule/arm64-apple-ios-simulator.swiftinterface"
rg -n "GlassButtonStyle|backgroundExtensionEffect|SpacerSizing" "$SWIFTUI" "$SWIFTUICORE"
sed -n '1200,1235p' "$SWIFTUI"
Use interface grep for:
- overload sets and generic constraints
@available, deprecation, and rename messages- internal-adjacent underscored declarations visible in the SDK
- declarations missing prose docs in symbol graphs
Symbol Graph Cache
The cache defaults to:
${CODEX_IOS26_DOCS_CACHE:-$HOME/.cache/codex/search-ios26-docs}/<sdk-name>/<target>/<module>/
Default modules are SwiftUI and SwiftUICore. Add more modules when needed:
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/build_cache.py --module UIKit --module Foundation
python3 "$HOME/.codex/skills/search-ios26-docs/scripts/search_symbols.py safeAreaRegions --module UIKit
Useful options:
build_cache.py --list prints cache location and SDK details without extracting.build_cache.py --force deletes and rebuilds selected module caches.search_symbols.py --json emits machine-readable results.search_symbols.py --verify-interfaces attaches matching .swiftinterface, header, or apinotes snippets and diagnostics to shown results.probe_symbol.py QUERY ... is shorthand for a verified, non-deduped symbol probe with full docs.search_symbols.py --find-module PATTERN lists SDK modules with names matching a substring.search_symbols.py --list-modules lists SDK framework modules visible to the helper.search_symbols.py --kind "Instance Method" narrows result kind.search_symbols.py --ios26 filters to symbols introduced in iOS 26 or later.search_symbols.py --introduced iOS:26 filters by an explicit availability domain and major version.search_symbols.py --no-doc hides doc snippets for compact output.search_symbols.py --no-dedupe keeps repeated extension results when every concrete receiver matters.search_symbols.py --source-limit 8 --source-context-lines 6 adjusts verified source snippets.
Test
Run the end-to-end tests after changing the helper scripts. They use the actual installed SDK and validate symbol graph search, verified source snippets, module discovery, and explicit module drill-down:
python3 "$HOME/.codex/skills/search-ios26-docs/tests/test_search_symbols_e2e.py"
Interpretation Rules
- Treat symbol graph docs as extracted local Apple SDK metadata, not generated guesses.
- Treat
.swiftinterface as the compiler-facing declaration source.
- Treat headers and apinotes as first-class fallback sources for Objective-C-backed frameworks.
- When symbol graphs and verified SDK source disagree, prefer the verified SDK source and report the mismatch.
- Do not assume public Apple Developer web pages are complete or current for iOS 26 beta/new SDK APIs.
- If symbol graph extraction fails for a module, fall back to
rg over framework interfaces under $SDK_PATH/System/Library/Frameworks and $SDK_PATH/System/Library/PrivateFrameworks.
- Report the active SDK basename, target triple, and module when precision matters.
