SwiftUI vs UIKit depends on your target OS and team expertise. SwiftUI offers modern declarative syntax and is ideal for iOS 13+, while UIKit provides broader backward compatibility. This Skill guides you through the trade-offs, covering patterns like TCA and MVVM to help align your choice with project requirements.

SwiftData is the recommended persistence framework for iOS 17+, replacing Core Data for many use cases. It integrates seamlessly with SwiftUI and offers simpler syntax. This Skill explains when to use SwiftData versus Core Data and how to structure your data layer accordingly.

Consistent architecture requires documented patterns and standards. This Skill provides high-level iOS architecture guidance using Context7 libraries to organize UI stack choices, data strategies, concurrency patterns, state management, and navigation—enabling aligned decisions across diverse agents and team members.

Yes, atom-based state management works well with SwiftData for iOS 17+ projects. This Skill covers how to integrate SwiftData persistence with atom-based state patterns to build scalable, maintainable applications with clear separation of concerns.

Modern iOS requires careful handling of async/await concurrency and navigation flows. This Skill provides architecture guidance on testing, navigation strategies, and concurrency patterns within OS 4.1 iOS planning, helping you implement robust, testable solutions.

Context7 libraries are integrated into this Skill to organize iOS patterns and standards. Familiarity helps, but this Skill is designed for architects and iOS specialists planning projects—it teaches how to apply Context7 libraries within architecture decisions.
