+// Swift Package Manager support for React Native's SwiftPM autolinking
+// (react-native >= 0.87, `npx react-native spm`). CocoaPods users are unaffected:
+// react-native-slider.podspec stays the source of truth there.
+//
+// The two React Native packages are resolved by the autolinker relative to
+// build/generated/autolinking/libs/react-native-slider in the app, as in
+// react-native-safe-area-context. They do not resolve in a bare clone.
