feat(macos): macOS support via RN's first-party SPM helper#30
Merged
Conversation
The original blocker for #27 wasn't Swift sources — it was cocoapods-spm 0.1.20 producing a malformed Pods.xcodeproj on Xcode 26 (UUID collision between its STTextView XCSwiftPackageProductDependency and the PBXProject root, causing Xcode to send `_setSavedArchiveVersion:` to the wrong type and bail). Issue trinhngocthuyen/cocoapods-spm#172 tracks it; no upstream fix and the RN community is migrating off the plugin. Switch the macOS path to React Native's first-party `spm_dependency` helper (lives in `react_native_pods.rb`, present in react-native-macos 0.81). It registers SPM products via Xcodeproj-direct, sidestepping the cocoapods-spm UUID allocator entirely. iOS-via-Expo-CNG keeps using cocoapods-spm via `app.plugin.js` — that path was never broken. Library - `ReactNativeSourceEditor.podspec`: add `:osx => '14.0'` and gate the SPM declaration on `ENV['RNSE_USE_RN_SPM']`. iOS branch keeps `s.spm_dependency 'STTextView/STTextView'` (cocoapods-spm); macOS branch calls RN's top-level `spm_dependency s, url:, requirement:, products:`. The gate can't be `s.respond_to?(:spm_dependency)` — cocoapods-spm monkey-patches Pod::Specification at gem load time globally whenever installed. - `ios/SourceEditor.mm`: guard the Swift bridging header import with `__has_include`. iOS gets `<ReactNativeSourceEditor/...>` (framework wrapper exists under `use_frameworks!`); macOS falls back to quote-form which picks up the header from DerivedSources/ (no .framework wrapper under default static-library linkage). Example app - `macos/Podfile`: drop `plugin 'cocoapods-spm'` and `spm_pkg`; set `ENV['RNSE_USE_RN_SPM'] = '1'`. Stay on static linkage (the SPM warning recommends dynamic, but `use_frameworks! :linkage => :dynamic` triggers a separate RN-macOS bug where React-Core's `RCTView.m` hardcodes a class ref to `RCTTextView` that doesn't resolve across dynamic frameworks). - `metro.config.js`: add `unstable_enablePackageExports` and `unstable_conditionNames: ['source', 'react-native', ...]` so metro reads the package's `source` exports condition (`src/index.ts`) instead of the unbuilt `lib/module/index.js`. Expo's metro config does this automatically for the iOS example; @react-native/metro-config does not. - `Info.plist`: add `RCTNewArchEnabled = true` for Fabric. - `MacosApp.xcodeproj`: Pods integration auto-edits from `pod install`. - `Podfile.lock`, `PrivacyInfo.xcprivacy`: track for reproducibility. - `README.md`: rewrite — now ships, documents toolchain choices. Hygiene - `.gitignore`: add `Pods/`, `MacosApp.xcworkspace/`, `.xcode.env*`, `.spm.pods/` under `example/macos-app/macos/`. - `package.json`: drop `macos:plugin` (installed cocoapods-spm — no longer needed on the macOS path).

Project hygiene now that #27 is closed: - README, docs/installation.md, docs/examples.md no longer say macOS is pending. Platform support tables, roadmap, and run instructions all reflect macOS shipping. - docs/installation.md: rewritten SPM bridging section. Two paths (cocoapods-spm for iOS-via-Expo-CNG, RN's first-party `spm_dependency` for bare react-native-macos) with full Podfile snippets, plus the static-linkage caveat and the fmt/Apple-Clang-17 patch pointer. - README's "Repo layout" updated: ios/ is shared across platforms (with `#if os(iOS) / #elseif os(macOS)` branching), example/macos-app/ is runnable, and `app.plugin.js` is iOS-only. - README's "Running the macOS example" section replaced with the actual npm scripts. Bump version 0.0.1 → 0.1.0 (still pre-npm; the README explicitly reserves npm publishing for v1.0). First milestone tag — both target platforms shipping. Add CHANGELOG.md following Keep a Changelog 1.1.0. The 0.1.0 entry covers all merged work to date (PRs #11 through #30). Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>

Summary
Pods.xcodeprojon Xcode 26 — a UUID collision between its STTextView `XCSwiftPackageProductDependency` and the `PBXProject` root object, causing Xcode to send `_setSavedArchiveVersion:` to the wrong type and bail. (cocoapods-spm#172 tracks it; no upstream fix.)Key changes
Plus auto-edits from `pod install` (Pods integration in pbxproj, `RCTNewArchEnabled = true` in Info.plist), `Podfile.lock` and `PrivacyInfo.xcprivacy` checked in for reproducibility, and `example/macos-app/README.md` rewritten to document the now-shipping workflow.
