// swift-tools-version: 6.0
//
// VoiceCatCore — the shared Swift core for the VoiceCat macOS (AppKit) and iOS (SwiftUI)
// clients. It wraps libvoicecat's C ABI (core/include/voicecat.h) as imported through the
// VoiceCatCore.xcframework binary target's module map (`import VoiceCatC`), and exposes a
// Swift-idiomatic, @MainActor-safe surface.
//
// Architecture: docs/architecture.md §4 ("one core, many faces"). The Windows C# client
// (clients/windows/VoiceCat.Interop) is the proven mirror of this same layering — the Swift
// wrapper follows the same patterns (callback-lifetime, string-lifetime, event-delivery
// thread handoff, immediate vc_free_* on list reads) adapted to Swift's interop model.
//
// The XCFramework is a LOCAL BUILD ARTIFACT — run `scripts/build-xcframework.sh` before
// `swift build` / `swift test`. See clients/apple/README.md.
