 MC-Vector is a cross-platform desktop app (Tauri v2 + React 19 + TypeScript) for Minecraft server management. It handles server lifecycle, real-time monitoring, plugin/mod browsing (Modrinth, Hangar, SpigotMC), file editing (Monaco Editor), backups, Java version management, and Ngrok integration.

+A macOS Tahoe (26)+ native app (Swift 6 / SwiftUI / AppKit) is planned as an independent reimplementation — not a shared-core port. See `spec/native-macos-requirements.md` for the full rationale. The SwiftPM package lives under `apps/native-macos/` — see `apps/native-macos/README.md` for build/lint commands.
 
 After any refactor: run `pnpm build` and confirm it succeeds before finishing.

+# MC-Vector Native (macOS)
+
+Independent Swift/SwiftUI reimplementation of MC-Vector for macOS Tahoe (26)+.
+See `spec/native-macos-requirements.md` for why this isn't a shared-core port,
+and `spec/phase-tasks.md` for the phase-by-phase task breakdown.
+
+No `.xcodeproj` — this is a plain SwiftPM package. `App` is a thin
+`@main` entry point; `Core` holds the actual views/logic (this split is what
+lets `#Preview` work without `ENABLE_DEBUG_DYLIB`, which can only be set via
+an `.xcodeproj`).
+
+## Requirements
+
+- macOS 26 (Tahoe)+
+- Xcode 26+ / Swift 6.2+
+
+## Commands
+
+Run from `apps/native-macos/`:
+
+```bash
+swift build   # build App + Core
+swift test    # run CoreTests (Swift Testing)
+```
+
+Format and lint are exposed as SwiftPM plugins:
+
+```bash
+# SwiftFormat (command plugin — no build-tool plugin exists upstream)
+swift package --allow-writing-to-package-directory swiftformat        # write
+swift package --allow-writing-to-package-directory swiftformat --lint # check only
+
+# SwiftLint (build-tool plugin — runs automatically as part of `swift build`/`swift test`)
+swift package --allow-writing-to-package-directory swiftlint --fix    # autocorrect
+```
+
+`lefthook` runs both automatically on commit for files under `apps/native-macos/**/*.swift`
+(see the `lint-format-swift` job in the root `lefthook.yml`); it no-ops with a message if
+`swift` isn't on `PATH` locally, since CI (`.github/workflows/native.yml`) is the enforcement
+backstop either way.
+
+## Opening in Xcode
+
+Xcode 26 can open `Package.swift` directly — no separate project file needed.
