Diagnose and recover from failures when building, running, or driving an app on the iOS Simulator. A living catalog organized by layer: build failures (xcodebuild, CocoaPods, signing, codegen), runtime failures split into app-runtime vs Expo-runtime (the red error overlay), and automation failures that emit no error (element not found in the accessibility tree, stuck flow). Each layer names where its logs live. Used alongside ios-simulator and expo-ios-simulator when something breaks.…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# iOS Simulator Triage (living failure catalog)

Classify first (which layer failed), then recover. Most fixes live in the sibling skills;
this skill routes you to them and supplies the logging tools that turn a symptom into a cause.

## Route by symptom

- **It never installs or launches** (xcodebuild, CocoaPods, or prebuild failed): a **build
  failure** -> `references/build-failures.md`.
- **It launches, then crashes or misbehaves**: a **runtime failure** ->
  `references/runtime-failures.md`, split into app-native and Expo / React-Native because
  the logs and the fixes differ.
- **It runs, but AXe cannot find or tap the element**: an **automation failure** ->
  `references/automation-failures.md`.

## Read the logs first

Every layer has a log that names the cause; guessing without it wastes a cycle.
`references/logging.md` is the cross-cutting tool, indexed by layer: the unified log
(`simctl spawn booted log stream`), the app's stdout and stderr (`simctl launch --console`),
crash reports, the diagnostic bundle (`simctl diagnose`), and the Metro terminal for the JS
layer.

## Rules

- Identify the layer before changing anything; a build fix will not cure a runtime crash.

How to install

The exact contents, by fingerprint
mdr add simiancraft/simiancraft-skills/ios-simulator-triage@sha256:4ba084e4e1743c25

The line at the top of this page pins the label git:20260701.bf690c7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
