Boutique is a Swift persistence library providing a simple Store API with memory + disk caching for state-driven apps. It offers property wrappers (@StoredValue, @SecurelyStoredValue) that expose persisted data as regular Swift arrays and values for SwiftUI, UIKit, and AppKit.

Use cases

• persist app state offline in a SwiftUI app
• replace Core Data with a simpler persistence layer
• cache API responses on disk with real-time updates
• store secure values like auth tokens
• build offline-first iOS apps with minimal code
• manage app state as a reactive Swift array

When to choose

• building SwiftUI, UIKit, or AppKit apps needing simple offline persistence
• you want state-driven architecture without database boilerplate
• you need both in-memory and disk caching with a tiny API

When to avoid

• building for platforms outside Apple's ecosystem
• you need complex relational queries or migrations that Core Data or SQLite provide
• server-side or non-Swift projects
