swiftui-patterns
by affaan-mswiftui-patterns is a practical guide for Frontend Development on Apple platforms. It covers SwiftUI state management, NavigationStack flows, view composition, and performance guidance so you can choose the right pattern for real app code. Use the swiftui-patterns skill when refactoring or building screens with clear ownership and fewer re-renders.
This skill scores 84/100, which means it is a solid listing candidate for directory users who want SwiftUI-specific guidance instead of a generic prompt. The repository shows a real, non-placeholder workflow-oriented skill with clear activation cues, detailed pattern guidance, and enough concrete SwiftUI content to justify installation.
- Clear activation scope for SwiftUI work: views, state management, NavigationStack, view models, performance, and dependency injection.
- Substantial instructional content with headings, tables, and code examples, which helps an agent apply the skill with less guesswork.
- No placeholder or experimental markers; the skill body is sizable and focused on modern Apple-platform SwiftUI patterns.
- No install command or supporting reference files, so users must rely on the SKILL.md content alone for adoption confidence.
- Coverage appears centered on patterns and best practices, so it may be less helpful for highly specific app-domain or debugging workflows.
Overview of swiftui-patterns skill
What swiftui-patterns is for
The swiftui-patterns skill helps you build SwiftUI screens with the right state, navigation, and composition patterns instead of reaching for generic prompt advice. It is best for Frontend Development work on Apple platforms when you want a practical guide for choosing @State, @Binding, @Observable, @Bindable, and @Environment in real app code.
Who should use it
Use the swiftui-patterns skill if you are:
- starting a new SwiftUI feature and need a clean architecture choice
- refactoring a view that has grown too stateful or hard to maintain
- adding
NavigationStackflows, list-heavy screens, or shared dependencies - trying to reduce unnecessary re-renders and improve view performance
Main value for install decisions
The repo is useful when the job is not “write any SwiftUI code” but “make a SwiftUI screen behave correctly and stay easy to change.” Its strongest signal is guidance around modern SwiftUI state management with @Observable, which is more actionable than a broad UI prompt because it pushes you toward the right ownership model and render boundary.
How to Use swiftui-patterns skill
swiftui-patterns install
Install the swiftui-patterns skill in your Claude Code skills directory, then invoke it on SwiftUI tasks that need architectural decisions. A typical install path is:
npx skills add affaan-m/everything-claude-code --skill swiftui-patterns
After installation, confirm the skill is available before using it on a feature branch or refactor.
What input it needs
The skill works best when you give it a concrete SwiftUI scenario, not a vague request. Include:
- platform target: iOS, macOS, or both
- screen type: list, detail, form, onboarding, settings, etc.
- state ownership: local, parent-owned, shared, or environment-based
- navigation shape: push, stack, sheet, split view, or deep link
- performance concern: large lists, frequent updates, expensive layout, etc.
A weak prompt is: “Improve this SwiftUI view.”
A stronger prompt is: “Refactor this SwiftUI list screen for iOS 17 using @Observable for model state, NavigationStack for drill-down, and minimize re-renders when a single item changes.”
Where to read first
For best swiftui-patterns usage, start with SKILL.md and focus on the sections that map to your problem: When to Activate, State Management, Property Wrapper Selection, and @Observable ViewModel. Those parts tell you when the skill applies and how it expects state to flow through the app.
Practical workflow
- Describe the feature or bug in terms of state ownership and navigation.
- Ask the model to choose the wrapper or pattern before it writes full code.
- Review whether the result uses the simplest state model that fits.
- If the output feels overbuilt, ask it to simplify ownership or remove unnecessary wrappers.
- Test the view with real updates, not just static rendering.
swiftui-patterns skill FAQ
Is swiftui-patterns only for new apps?
No. The swiftui-patterns skill is also useful for existing codebases, especially when you want to replace older ObservableObject patterns, reduce view coupling, or clean up navigation and list performance without rewriting everything.
How is it different from a normal prompt?
A normal prompt may generate SwiftUI code, but swiftui-patterns gives you a decision framework for choosing the right pattern first. That matters when the main risk is not syntax but incorrect state ownership, unnecessary redraws, or brittle navigation.
Is it beginner-friendly?
Yes, if you use it as a guided decision tool. The skill is most helpful when you have a specific screen in mind and want to learn which wrapper or composition approach fits, rather than memorizing SwiftUI theory.
When should I not use it?
Do not rely on swiftui-patterns if your task is mostly UIKit, server-side Swift, or a non-Apple frontend. It is also not the best fit for purely visual design work that does not involve state, flow, or rendering behavior.
How to Improve swiftui-patterns skill
Give the model the ownership story
The best results come when you explain who owns each piece of state. For example, say whether a form field belongs to the view, whether a model is passed down from a parent, or whether several screens need the same source of truth. That is the fastest way to get better swiftui-patterns output.
Ask for wrapper justification
If you want higher-quality answers, ask the skill to explain why it chose @State, @Binding, @Observable, @Bindable, or @Environment. This reduces accidental overuse of wrappers and helps you catch mismatches before they reach implementation.
Watch for common failure modes
The main failure mode is overengineering: using shared state or an observable model when local state would be simpler. Another is vague navigation guidance that ignores real app flow. Improve the prompt by naming the exact user action, the destination screen, and what should persist after navigation.
Iterate with a concrete code sample
After the first output, paste the actual SwiftUI view or view model and ask for a targeted rewrite. Mention what you want improved, such as fewer recomputations, simpler bindings, or cleaner composition. For swiftui-patterns for Frontend Development, this is usually the fastest path from general advice to shippable SwiftUI code.
