swift-patterns
by efremidzeswift-patterns is a SwiftUI skill for reviewing, refactoring, or building features with correct state ownership, modern navigation, clean view composition, lifecycle-scoped async work, and performance checks. Use this swift-patterns guide when you need practical, repository-backed help for frontend development instead of generic advice.
This skill scores 83/100, which means it is a solid directory listing for users who want a SwiftUI-specific review/refactor helper rather than a generic prompt. The repository gives enough workflow structure, references, and decision guidance for an agent to trigger the skill and act with less guesswork, though it is more guidance-heavy than executable-tool-heavy.
- Explicit trigger scope for reviewing, refactoring, or building SwiftUI features with state, navigation, performance, and testing guidance.
- Strong workflow organization with a decision tree and 14 reference files covering review, refactor, state, navigation, concurrency, lists, and modern APIs.
- Good operational clarity from concrete anti-patterns, best-practice tables, and reusable patterns that reduce ambiguity for agents.
- No install command or scripts, so adoption is documentation-driven rather than tool-assisted.
- The skill is broad and reference-rich, but users needing a narrowly scoped task flow may still need to choose among multiple reference files.
Overview of swift-patterns skill
What swift-patterns is for
The swift-patterns skill helps you review, refactor, or build SwiftUI features using current Apple-friendly patterns: correct state ownership, modern navigation, clean view composition, lifecycle-scoped async work, and practical performance checks. It is most useful when you need a swift-patterns guide for real code, not a generic SwiftUI opinion dump.
Best-fit readers and jobs
Use the swift-patterns skill if you are shipping SwiftUI and need help deciding whether code should be rewritten, extracted, or simply corrected. It fits frontend teams working in SwiftUI who want fewer regressions from duplicated state, unstable lists, legacy navigation, or expensive view bodies.
What makes it different
This skill is opinionated toward native APIs and maintainable structure, but it does not force a specific architecture. That matters if you want a practical review aid rather than a coordinator or MVVM prescription. The repository is organized around workflows and references, which makes swift-patterns better for diagnosis and targeted fixes than for one-off prompts.
How to Use swift-patterns skill
Install and trigger it
Use swift-patterns install in the sense of adding the skill to your agent workspace, then invoke it on a concrete SwiftUI task. The repo’s install command is:
npx skills add efremidze/swift-patterns-skill --skill swift-patterns
Give the skill the right input
The skill works best when you provide:
- the feature goal
- the current SwiftUI code or file names
- deployment target details
- any constraints on navigation, state, or async behavior
- the actual bug, smell, or refactor target
A weak prompt is: “improve this SwiftUI view.”
A stronger prompt is: “Review FeedView.swift for unstable ForEach identity, duplicated loading state, and any legacy navigation APIs. Keep the current UX and target iOS 17+.”
Read the repo in the right order
For swift-patterns usage, start with SKILL.md, then inspect:
references/workflows-review.mdreferences/workflows-refactor.mdreferences/state.mdreferences/navigation.mdreferences/modern-swiftui-apis.mdreferences/performance.md
If you are changing lists, scrolling, or composition, also open:
references/lists-collections.mdreferences/scrolling.mdreferences/view-composition.mdreferences/refactor-playbooks.md
Use the workflow, not just the topic
The strongest swift-patterns results come from matching the task to the workflow:
- Review: ask for issues, risk level, and why each issue matters.
- Refactor: ask for a stepwise rewrite plan and minimal behavior changes.
- Build new feature: ask for a SwiftUI implementation that follows native patterns from the start.
swift-patterns skill FAQ
Is this only for SwiftUI review?
No. The swift-patterns skill covers review, refactor, and new feature work. It is still centered on SwiftUI patterns, so it is most valuable when your output needs to be code-adjacent and implementation-ready.
How is this different from a normal prompt?
A normal prompt often asks for “best practices” and gets broad advice. swift-patterns is more useful because it points the agent toward specific decision areas: state, navigation, lists, concurrency, and performance. That reduces guesswork and makes the swift-patterns install decision easier when you want consistent review depth.
Is it a good fit for beginners?
Yes, if the beginner is working in SwiftUI and wants guardrails. It is not a tutorial skill; it is better for people who already have code and need to correct it. Beginners get the most value when they paste the file and ask for a focused review.
When should I not use it?
Do not use swift-patterns for app-wide architecture debates, UIKit-heavy work, or non-Swift platforms. It is also a poor fit if you only need a quick slogan-style answer and do not want repository-backed reasoning.
How to Improve swift-patterns skill
Give it sharper constraints
The skill improves when you specify platform, target OS, and what must not change. For example: “Keep support for iOS 16,” “avoid introducing a coordinator,” or “do not change the navigation model.” This prevents the model from recommending modern APIs you cannot actually ship.
Ask for the specific failure mode
Most weak outputs come from vague requests. Better inputs name the defect:
- “row selection resets after deletion”
- “task restarts too often on filter changes”
- “view body is recreating formatters”
- “navigation pushes from two places”
That helps swift-patterns focus on the real cause instead of rewriting unrelated code.
Iterate from review to patch
For best results, first ask for a diagnosis, then ask for the smallest safe patch. If the first answer suggests state or navigation changes, follow up with the exact file and ask for a revised implementation plus tradeoffs. This is where swift-patterns for Frontend Development is most useful: it turns review comments into code changes you can apply with confidence.
