23 Agent Skills for iOS 26 Development with SwiftUI and Swift 6.2
A developer on r/ClaudeAI has built 23 agent skills specifically for iOS development to address common issues with AI coding assistants. The skills target iOS 26+ and Swift 6.2, with best practices included and no deprecated APIs.
Problem Being Solved
The developer found that general-purpose models were "constantly hallucinating deprecated APIs, generally mixing up old and new patterns, and have no clue about iOS 26 stuff like Liquid Glass or Foundation Models." Installing these skills has "fixed most of the hallucination issues" and results in agents producing "much more accurate and up-to-date code, whilst avoiding the old patterns."
Skill Coverage
The skills cover most of the iOS development surface area:
- SwiftUI patterns
- SwiftData
- StoreKit 2
- Push notifications
- Networking
- Concurrency
- Accessibility
- Localization
- WidgetKit
- MapKit
- And more
Installation Instructions
For Claude Code:
Add the marketplace (one-time): /plugin marketplace add dpearson2699/swift-ios-skills

Or install themed bundles:
/plugin install swiftui-skills@swift-ios-skills /plugin install swift-core-skills@swift-ios-skills /plugin install ios-framework-skills@swift-ios-skills /plugin install ios-engineering-skills@swift-ios-skills
For Claude Web App or Claude Desktop:
- Download the skill folder(s) you want from the repo and zip each one
- Go to Settings > Capabilities and make sure "Code execution and file creation" is on
- Go to Customize > Skills, click "+", then "Upload a skill"
- Upload the zip
Skill Design Considerations
The developer paid "special attention when making the description of the skills" following best practices from the Claude platform documentation. They went through "a few rounds of optimizing the descriptions so they get called as reliably as possible, since that's the only thing the agent sees when deciding which skill to load." All skills are self-contained so developers can "just grab the ones you actually need."
