voice-cat/clients/apple/Package.swift

// 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.

    // target (clients/apple/iOS/) — 18.0 unlocks the newest AVAudioSession APIs (stereo capture,
    // polar patterns, data sources). Run `scripts/build-xcframework.sh --all` to produce all
    // three slices: macos-arm64, ios-arm64, ios-arm64-simulator.
    // swift-tools-version 6.0 is required for .iOS(.v18); swiftLanguageVersions .v5 keeps the
    // Swift 5 language mode (avoids Swift 6 strict concurrency checking on pre-existing code).
