OpenClaw Skills for Swift and iOS Development

iOS development moves fast. SwiftUI evolves with every WWDC, Swift concurrency has replaced completion handlers and Combine for many use cases, and Apple's review guidelines change quarterly. AI agents trained on general data often generate UIKit patterns when you want SwiftUI, use deprecated APIs, or miss Apple's platform-specific conventions that determine whether your app passes App Store review.

OpenClaw skills keep your agent current with modern Swift and iOS development. This guide covers the most valuable skills for iOS developers, all available in the OpenClaw Bazaar skills directory.

SwiftUI Skills

swiftui-modern-patterns

Installs: 10,320 | Rating: 4.8/5

This is the most-installed iOS skill on the Bazaar, and it is essential for any developer building with SwiftUI. It teaches your agent the latest SwiftUI patterns — declarative view composition, state management with @State, @Binding, @StateObject, @ObservedObject, and the newer @Observable macro, navigation with NavigationStack and NavigationSplitView, and the environment system with @Environment and @EnvironmentObject.

openclaw skill install swiftui-modern-patterns

After installing, your agent will generate SwiftUI views that follow Apple's latest recommendations — using @Observable instead of ObservableObject where appropriate, applying the NavigationStack API instead of the deprecated NavigationView, and structuring views with proper composition rather than massive view bodies.

swiftui-layout-system

Installs: 5,870 | Rating: 4.7/5

SwiftUI's layout system is powerful but has subtle behaviors that trip up developers and AI agents alike. This skill covers HStack, VStack, ZStack, LazyVGrid, LazyHGrid, GeometryReader, and the custom layout protocol. It teaches your agent how SwiftUI's layout negotiation works — how parent and child views communicate size preferences, how priority modifiers affect layout, and how to use frame, padding, and alignment correctly.

openclaw skill install swiftui-layout-system

The skill also covers adaptive layouts that work across iPhone, iPad, and Apple Watch, including size classes, dynamic type, and accessibility scaling.

swiftui-animations

Installs: 4,150 | Rating: 4.6/5

Animations are what separate a functional app from a polished one. This skill teaches your agent SwiftUI's animation system — implicit animations with .animation(), explicit animations with withAnimation, matched geometry effects for hero transitions, phase animators, and keyframe animations introduced in recent iOS versions. Your agent will apply animations that follow Apple's Human Interface Guidelines for timing curves and motion design.

Swift Concurrency: async/await

swift-concurrency-patterns

Installs: 8,960 | Rating: 4.8/5

Swift's structured concurrency model — async/await, Task, TaskGroup, actors, and Sendable — is the modern way to handle asynchronous work in iOS applications. This skill teaches your agent to use these primitives correctly, replacing the completion handler patterns that still dominate many codebases.

openclaw skill install swift-concurrency-patterns

The skill covers async let for parallel execution, TaskGroup for dynamic concurrency, MainActor for UI-bound code, actor isolation for safe state management, and AsyncSequence and AsyncStream for asynchronous iteration. It also addresses the transition from Combine to async/await, showing your agent when each approach is appropriate.

swift-actor-isolation

Installs: 3,480 | Rating: 4.6/5

Actors are Swift's mechanism for safe concurrent state access, but the isolation rules can be confusing. This skill focuses specifically on actor design — when to use actors vs classes, nonisolated methods, cross-actor calls, global actors, and the @Sendable closure requirements that arise when passing data across isolation boundaries.

openclaw skill install swift-actor-isolation

With strict concurrency checking becoming the default, this skill helps your agent write code that compiles cleanly under strict mode without scattering @unchecked Sendable conformances everywhere.

Core Data and SwiftData

swiftdata-patterns

Installs: 6,740 | Rating: 4.7/5

SwiftData is Apple's modern persistence framework that replaces Core Data for new projects. This skill teaches your agent @Model macro usage, schema definition with relationships, @Query for fetching data in SwiftUI views, model containers and contexts, and migration strategies from Core Data.

openclaw skill install swiftdata-patterns

Your agent will generate SwiftData models that use the macro-based syntax correctly, define relationships with proper delete rules, implement predicate-based queries, and handle the integration between SwiftData and SwiftUI views naturally.

core-data-advanced

Installs: 4,920 | Rating: 4.6/5

Many existing applications still use Core Data, and migrating to SwiftData is not always practical. This skill covers Core Data's advanced features — NSFetchedResultsController for efficient list updates, batch operations for bulk inserts and deletes, background context patterns, lightweight migrations, and CloudKit integration with NSPersistentCloudKitContainer.

openclaw skill install core-data-advanced

The skill also covers Core Data performance patterns — prefetching, faulting behavior, and fetch request optimization that keep your application responsive when working with large datasets.

Testing with XCTest

swift-xctest-patterns

Installs: 6,380 | Rating: 4.7/5

Testing iOS applications involves unique challenges — UI testing, async code testing, mock injection without protocols everywhere, and testing SwiftUI views. This skill covers unit tests with XCTest, async test methods with async throws, test doubles and dependency injection patterns, and expectations for testing asynchronous callbacks.

openclaw skill install swift-xctest-patterns

Your agent will write tests that handle common iOS testing patterns — testing view models in isolation, mocking network layers with URLProtocol, and verifying state changes driven by user interactions. The skill also covers the Swift Testing framework for projects adopting Apple's newer testing approach.

swift-ui-testing

Installs: 3,650 | Rating: 4.5/5

UI testing in iOS requires a different approach than unit testing. This skill covers XCUITest — launching the app in a test process, querying UI elements, simulating user interactions (taps, swipes, text entry), and writing assertions against the UI state. It also covers snapshot testing approaches and accessibility identifier strategies that make UI tests reliable.

swift-preview-testing

Installs: 2,890 | Rating: 4.4/5

SwiftUI previews are not just for development — they can be used for visual regression testing. This skill teaches your agent to write effective previews with sample data, preview different device sizes and dynamic type settings, and integrate preview-based snapshot testing into the CI pipeline.

App Store Guidelines

ios-app-store-guidelines

Installs: 5,510 | Rating: 4.7/5

App Store rejections waste days of development time. This skill teaches your agent the guidelines that most commonly cause rejections — in-app purchase requirements, privacy manifest declarations, data collection disclosures, login requirements, push notification best practices, and content rating accuracy.

openclaw skill install ios-app-store-guidelines

When your agent generates code that involves payments, user data, or Apple services, it will proactively follow the guidelines that govern those features. The skill is updated regularly to reflect the latest changes to Apple's review process.

ios-privacy-manifest

Installs: 4,270 | Rating: 4.6/5

Apple now requires privacy manifests (PrivacyInfo.xcprivacy) for apps and third-party SDKs. This skill teaches your agent to declare required reason APIs correctly, list data collection types accurately, and generate privacy manifests that match the app's actual behavior. It covers the required reason API categories — file timestamp access, user defaults, system boot time, and disk space — and the corresponding reasons your app can declare.

Platform Integration

ios-networking-urlsession

Installs: 5,130 | Rating: 4.6/5

Networking is fundamental to most iOS applications. This skill covers URLSession with async/await, request construction, response handling, authentication challenges, background downloads, and certificate pinning. It also covers common architectures — protocol-based API clients, request/response middleware, and retry logic.

openclaw skill install ios-networking-urlsession

ios-notifications-push

Installs: 3,340 | Rating: 4.5/5

Push notifications involve registration, token handling, payload parsing, and background processing. This skill covers the UNUserNotificationCenter API, remote notification setup, notification content extensions, and the background processing rules that affect how your app handles notifications when not in the foreground.

Recommended Skill Combinations

A typical iOS developer building a modern SwiftUI application should install:

1. swiftui-modern-patterns for view development
2. swift-concurrency-patterns for async code
3. swiftdata-patterns for persistence
4. swift-xctest-patterns for testing
5. ios-app-store-guidelines for submission readiness

For developers maintaining existing UIKit applications, replace swiftui-modern-patterns with the UIKit-focused skills available on the Bazaar, and use core-data-advanced instead of swiftdata-patterns.
