ios-build-fix

ios-build-fix is a skill for Claude Code, Codex from OutlineDriven/odin-claude-plugin. It costs 49 tokens per session (2,398 once invoked), scanned A, original, Apache-2.0.

A workflow for diagnosing and fixing a failing iOS build or user-interface behaviour through an iOS debug bridge.

In plain words
What is it for?
It is for tracing an iOS failure, applying a source fix, and verifying it on a simulator or device with a regression test.
Why use it?
It requires a reproduced failure and supporting evidence before changing Swift source, which helps connect the fix to the actual problem.

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 A, and why

ios-build-fix scanned grade A with 0 findings 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

iOS build fix

Mode A — Debug-bridge UI-fix

Contract

Field Bound contract
Trigger the user runs /ios-build-fix
Authority Reversible local: writes the iOS project's Swift source plus snapshot and screenshot fixtures and the regression test under test/fixtures/ios-fix/, applied and verified through the iOS debug bridge; rollback is version control. No remote mutation. The user picks among competing root-cause fixes.
Side effect project code changes edited directly, rebuilt and verified through the debug bridge, plus snapshot and screenshot fixtures and a regression test written under test/fixtures/ios-fix/
Done the failing iOS behavior is fixed and verified on a device or simulator, with a reproducing snapshot and a regression test committed alongside the fix

Inputs

Required:

  • A bug finding with a description of the failing behavior, a screenshot, and the suspected accessibility-tree node. Supplied by the user or a prior QA pass.
  • The iOS debug bridge (StateServer) running with a connected device or simulator, identified by UDID.
  • The Xcode scheme name and build destination.

Optional:

  • The user's choice among plausible root causes, if more than one remains after source tracing.

Procedure

  1. Do not edit any Swift source until a GET /state/snapshot that reproduces the bug is captured. A fix without a reproducing snapshot is rejected.
  2. Read the bug finding (description, screenshot, suspected accessibility-tree node).
  3. Drive the device into the bug state through the debug bridge: POST /tap, POST /swipe, POST /type, or POST /state/<key> (snapshot-eligible fields only).
  4. Capture GET /state/snapshot and write it to test/fixtures/ios-fix/<bug-slug>-pre.json.
  5. Capture GET /screenshot and write it to test/fixtures/ios-fix/<bug-slug>-pre.png.
  6. Record one line stating what is wrong and the expected behavior.
  7. Locate the root cause. Read the Swift source and trace the buggy screen back to the view model, data flow, and state mutation. Identify the smallest change that fixes the behavior.
  8. If more than one plausible root cause remains, present them to the user and let the user pick the one to fix before editing.
  9. Apply the fix: edit the Swift source, keeping the diff minimal. Rollback path: git checkout -- <edited files> reverts this edit.
  10. Rebuild and reinstall: xcodebuild -scheme <SchemeName> -destination <BuildDestination> build, then xcrun simctl install <UDID> <app-path> on a simulator or ios-deploy --bundle <app-path> --id <UDID> on a device. The daemon reconnects the StateServer tunnel after the rebuild; re-deploy through the boot-token rotation flow.
  11. Verify: POST /state/restore with the pre-bug snapshot to reproduce the state, then take a fresh GET /screenshot and compare it against test/fixtures/ios-fix/<bug-slug>-pre.png.
  12. If the bug visibly persists, the fix did not work: revert the Swift edit (git checkout -- <edited files>) and retry from step 9, up to 3 iterations before escalating to the user.
  13. If the bug is gone, capture test/fixtures/ios-fix/<bug-slug>-post.png.
  14. Add a regression test at test/fixtures/ios-fix/<bug-slug>.test.ts that loads the pre-bug snapshot, restores it via POST /state/restore, and asserts the post-fix behavior on a real device (gated on a device-available flag).
  15. Commit the snapshot fixture, the pre-fix and post-fix screenshots, and the regression test alongside the Swift fix.

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.
