We noticed that your app contains irrelevant platform information in the binary. Referencing third-party platforms in your app or its metadata is not appropriate on the App Store.
Specifically, your application includes imagery of a non-iDevice.
We’ve attached screenshot(s) for your reference.
Next Steps
Please remove any instances of this information from your app and its marketing materials, including the Application Description, What's New info, Previews and screenshots.
Since your iTunes Connect Application State is Rejected, a new binary will be required. Make the desired metadata changes when you upload the new binary.
NOTE: Please be sure to make any metadata changes to all App Localizations by selecting each specific localization and making appropriate changes.
