SwiftUI Convenience Layer (Host + UI)

This release adds a SwiftUI “convenience layer” on top of the core StoreKit 2 backend.

What’s new
• SwiftUI bootstrap
• PurchaseKitHost to own a single PurchaseKitManager (@StateObject) and inject it via EnvironmentObject
• View.installPurchaseKit(...) helpers (basic, with optional NetworkService, or custom manager factory)
• Package-ready UI components
• PurchaseKitPurchaseButton with sensible defaults and full customization via title/icon/tint providers
• Default localization keys resolved from Bundle.module
• Toolbar menu + legal actions
• PurchaseKitInfoToolbar with optional Terms/Privacy URLs, Info sheet, Restore, and Manage Subscriptions entry
• PurchaseKitSafariView for in-app web presentation
• Documentation
• Updated usage examples and setup guidance

Notes
• Minimum requirements unchanged (iOS 16+, StoreKit 2)
• No breaking API changes intended (compatible with v0.1.0 core)

PurchaseKit v0.1.0

🎉 Initial release

PurchaseKit is an app-agnostic StoreKit 2 backend as a Swift Package.

Highlights

• StoreKit 2 product loading with caching (CachePolicy)
• Purchase flow with verification + finishing transactions
• Restore flow via AppStore.sync() and entitlement snapshot
• Normalized entitlement model (EntitlementState) for feature gating
• Type-erased options (AnyPurchaseOption) for stable delegate callbacks
• Optional network awareness via NetworkService
• SwiftUI-ready building blocks + ObservableObject state
• Apache-2.0 licensed

Requirements

• iOS 16+
• Swift Package Manager
• StoreKit 2

Language / Localization

PurchaseKit ships with Localizable.xcstrings:

• English (en)
• German (de)
• You can override all strings in the host app by providing the same keys in your own localization files.

Notes

• API may evolve until v1.0.0 (breaking changes possible in minor versions).
