# SFSafariCorrespondingIOSAppBundleIdentifier

A string bundle ID that identifies the corresponding iOS app that contains a content blocker or Safari web extension.

## Discussion

To enable extension syncing for your macOS app that contains a content blocker or Safari web extension, specify the bundle ID of the corresponding iOS app that contains the same content blocker or Safari web extension.

Only add this to your `Info.plist` if the bundle ID for your macOS app is different from the bundle ID for your iOS app.

For more information, see <doc://com.apple.documentation/documentation/SafariServices/syncing-safari-web-extensions-across-devices-and-platforms>.
