build-ios-binary

build-ios-binary is a skill for Claude Code, Codex from microsoft/power-platform-skills. It costs 200 tokens per session (3,815 once invoked), scanned C, original, MIT.

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.

About the project

microsoft/power-platform-skills is a plugin marketplace containing reusable skills, agents, and commands for developing with Microsoft Power Platform. Developers use it to build and deploy Power Pages sites, model-driven Power Apps, and related solutions through Claude Code or GitHub Copilot. The catalogue entries are the marketplace's included skills, agents, plugins, and other agent components.

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 yesterday.

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.

What this file has done since we first saw it

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 (814 stars, last pushed yesterday), licensed MIT. It adds 200 tokens to every session and 3,815 once invoked, about $0.0010 per session on Opus 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.
