Curated by Skill Harbor: a pattern library for building declarative, performant interfaces with modern SwiftUI on Apple platforms. Covers the Observation framework (@Observable with property-level tracking instead of the older ObservableObject, so only views reading a changed property re-render), a property-wrapper selection guide (@State, @Binding, @Bindable, @Environment and when each one earns its place), view composition (extracting small focused subviews to limit invalidation, reusable styling through ViewModifiers), type-safe navigation with NavigationStack and NavigationPath driven by an observable router, and render performance (lazy containers for large collections, stable identifiers in ForEach, keeping I/O out of body, Equatable conformance for expensive views). Includes #Preview recipes with inline mock data for fast iteration and a sharp anti-pattern list (async work in body or init, AnyView type erasure, creating view models in child views that do not own the data, ignoring Sendable). The emphasis is on judgment, not syntax: which pattern fits which situation. By @affaan-m, listed here with credit to its creator. From the affaan-m/ECC repository (MIT). Honest caveats: pure guidance, nothing to install; Swift and SwiftUI oriented throughout, so you need an Apple-platform codebase (iOS, macOS) to apply it. Skill Harbor never reviews the code, review it yourself before use.

Install
Copy the install package below, then paste it into MuseWe automatically scan every listing and flag anything suspicious, but we can't review every line of community code. Here's how to check a build yourself before you install it.
Use "SwiftUI Patterns" with your Muse. Prerequisites: the Muse app (mobile or web). Pure guidance skill, nothing to install. A SwiftUI codebase (iOS, macOS) to build or review. 1. Open the skill: https://github.com/affaan-m/ECC/blob/main/skills/swiftui-patterns/SKILL.md and copy the full SKILL.md text. 2. Paste it into a chat with Muse and add: "Review [this view / this state logic] against these SwiftUI patterns: [paste your code or describe the screen]." 3. Ask Muse to flag pattern violations (ObservableObject in new code, async work in body, AnyView type erasure, missing stable identifiers in ForEach) and propose the corrected shape with before/after code. Tip: ask for the "why" behind each flagged pattern, not just the fix. The judgment transfers to the next view you write. Safety: a skill is plain-text instructions; it runs nothing by itself. Review any code before committing it, never paste secrets into a chat, and review anything Muse proposes before it acts.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
