developing-ios-apps

Develops iOS/macOS apps with XcodeGen, SwiftUI, and SPM, including Apple Developer signing, notarization, and CI/CD pipelines. Use when building iOS/macOS apps, fixing Xcode build failures, deploying to real devices, or configuring CI/CD signing. Triggers on XcodeGen project.yml, SPM dependency issues, code signing errors (Error -25294, keychain mismatch, adhoc fallback, EMFILE, notarization credential conflict), "Library not loaded @rpath", Electron @electron/osx-sign / @electron/notarize, notarytool, or certificate/provisioning problems.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a strong, well-structured skill that covers a complex domain (iOS/macOS development, signing, and CI/CD) with high actionability and clear workflows. The progressive disclosure is excellent, keeping the main file as an actionable overview while pointing to detailed references. Minor verbosity in explanatory sections (e.g., why dynamic frameworks need embedding) could be trimmed, but overall the content is efficient and immediately useful.

DimensionReasoningScore

Conciseness

Generally efficient with good use of tables and code blocks, but some sections include explanations Claude would already know (e.g., explaining what dynamic vs static frameworks are, explaining why SPM embedding matters). The 'Why This Happens' section under SPM could be trimmed. Some sections like the Free vs Paid comparison table and the camera debugging checklist are well-condensed.

2 / 3

Actionability

Highly actionable throughout — provides executable code snippets, exact bash commands, complete YAML configurations, specific error messages with solutions, and copy-paste ready patterns. The code signing checklist, XcodeGen config, and camera mirroring fix are all immediately usable.

3 / 3

Workflow Clarity

Multi-step processes are clearly sequenced with explicit validation checkpoints. The code signing section has a numbered 5-step checklist with critical details at each step, a fail-fast three-layer defense pattern, and verification commands. The SPM dynamic framework fix has a clear ordered sequence. The device deployment first-time setup is well-sequenced.

3 / 3

Progressive Disclosure

Excellent progressive disclosure structure — the main SKILL.md provides actionable overviews and quick references, then clearly signals deeper content via well-labeled references (camera-avfoundation.md, apple-codesign-notarize.md, xcodegen-full.md, etc.). References are one level deep and clearly signaled with descriptive labels. The Resources section at the bottom provides a clean navigation index.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is an excellent skill description that clearly defines its scope around Apple platform development with specific tooling, provides comprehensive trigger terms including exact error codes and tool names, and explicitly states both what it does and when to use it. The description is detailed without being padded, uses third person voice correctly, and would be highly distinguishable from other skills in a large collection.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: developing iOS/macOS apps with XcodeGen/SwiftUI/SPM, Apple Developer signing, notarization, CI/CD pipelines, fixing Xcode build failures, deploying to real devices, and configuring CI/CD signing.

3 / 3

Completeness

Clearly answers both 'what' (develops iOS/macOS apps with specific tooling, signing, notarization, CI/CD) and 'when' with an explicit 'Use when...' clause and a detailed 'Triggers on...' clause covering specific scenarios and error conditions.

3 / 3

Trigger Term Quality

Excellent coverage of natural trigger terms users would actually encounter: specific error codes (Error -25294), tool names (XcodeGen, notarytool, @electron/osx-sign), file references (project.yml), and common error phrases ('Library not loaded @rpath', 'keychain mismatch', 'EMFILE'). These are terms developers would naturally use when seeking help.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive niche combining Apple platform development with specific tooling (XcodeGen, SPM), code signing, notarization, and very specific error codes/messages. Unlikely to conflict with generic coding skills or other platform-specific skills.
