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

100%

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

The SKILL.md body is well-structured, actionable, and token-efficient, with clear workflows and clean progressive disclosure to verified reference files. It avoids basic-concept padding while providing executable, validated guidance.

DimensionReasoningScore

Conciseness

Lean, table- and code-driven content that assumes Claude's competence; no padding explaining what iOS, SPM, or code signing fundamentally are, and every block earns its place.

3 / 3

Actionability

Copy-paste-ready project.yml, executable xcodebuild/xcodegen commands, and concrete Swift before/after fixes give fully actionable guidance rather than vague direction.

3 / 3

Workflow Clarity

Multi-step processes (SPM embed fix, device deployment, lowering deployment target) are explicitly sequenced with validation checkpoints, a fail-fast three-layer defense, debug checklists, and error-recovery loops.

3 / 3

Progressive Disclosure

The body is a concise overview that signals one-level-deep references to five real files (all present under references/), with no nested reference chains and a clear Resources index for navigation.

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.

The description is specific, trigger-rich, and explicitly covers both capabilities and activation conditions in third person. It is a strong, low-conflict skill description that would be reliably selected for the right tasks.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Develops iOS/macOS apps with XcodeGen, SwiftUI, and SPM', 'Apple Developer signing, notarization, and CI/CD pipelines' — naming specific tools rather than abstract capabilities.

3 / 3

Completeness

Explicitly answers both what (develops/signs/deploy iOS/macOS apps) and when via a clear 'Use when...' clause plus an enumerated 'Triggers on...' list.

3 / 3

Trigger Term Quality

Strong coverage of natural terms users would say: 'building iOS/macOS apps', 'fixing Xcode build failures', 'SPM dependency issues', 'code signing errors', plus concrete error strings and tool names (notarytool, project.yml).

3 / 3

Distinctiveness Conflict Risk

Narrow niche (iOS/macOS + XcodeGen/SPM) with highly specific triggers like 'Error -25294' and '@electron/osx-sign', making conflict with other skills unlikely.

100%

Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
