A Mac-only build workflow that compiles a Power Apps Mobile control's iOS Swift or Objective-C code into the flat framework format required by the runtime.

In plain words
What is it for?
It is for building the iOS binary that becomes part of a .ppmplugin package for Power Apps Mobile.
Why use it?
It produces the correct iOS device framework and checks the native module setup needed for loading.

Written for Claude Code: allowed-tools in frontmatter. Also seen: model in frontmatter; names the AskUserQuestion tool.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **Ship a FLAT `.framework`, NOT an `.xcframework`.** The wrap pipeline expects `ios/<Name>.framework` and does not descend into an `.xcframework` — shipping one.

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

build-ios-binary scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/build-ios-binary

Turns the extension's iOS source (ios/RCT<Pascal>Module.{h,m}) into the flat <Pascal>Plugin.framework/ (device slice) that the wrap runtime loads. iOS analogue of /build-android-binary: source in, a prebuilt framework out.

Ship a FLAT .framework, NOT an .xcframework. The wrap pipeline expects ios/<Name>.framework and does not descend into an .xcframework — shipping one fails with "Framework '.framework' not found in plugin." This skill builds the device archive only and copies out the flat .framework. See ppmplugin-format §5b.

Mac-only. Requires Xcode. On Linux/Windows this skill BLOCKs — Android-only contributors can't produce the iOS slice.

KNOWN LIMITATION — read this. The single hard part is React-Core: the framework compiles against React's headers (#import <React/RCTBridgeModule.h>) from the control repo's own pinned react-native devDep, while never embedding React — the wrap host provides it at runtime (weak-link). The coupling that matters is the RN version pin (0.79.7): it must match the RN the wrap host ships. The exact weak-link flags / header-search-path setup aren't yet validated against a live wrap host — that's the main risk area. React symbol/header errors mean the RN pin diverged from the host's RN, not a code bug.

Read shared/ppmplugin-format.md §5b (iOS binary requirements) and the naming-conventions.md iOS rows.

What this skill does NOT do

  • Does not author manifest.json (run /generate-ppmplugin-manifest first — this skill reads it for cross-checks and the framework/moduleClass names).
  • Does not zip the .ppmplugin — that's /assemble-ppmplugin.
  • Does not build Android — that's /build-android-binary.
  • Does not modify the canonical ios/ or the podspec — all adjustments live in a throwaway copy under ppmplugin/staging/ios-build/.
  • Does not sign the framework — the wrap pipeline signs at packaging time (given BUILD_LIBRARY_FOR_DISTRIBUTION=YES SKIP_INSTALL=NO). No signing skill needed.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

build-ios-binary is a skill published in the GitHub repository microsoft/power-platform-skills (1,042 stars, last pushed today), licensed MIT. It adds 200 tokens to every session and 3,815 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
