Apple Worldwide Developer Relations Intermediate Certificate Expiration
To help protect customers and developers, we require that all third party apps, passes for Apple Wallet, Safari Extensions, Safari Push Notifications, and App Store purchase receipts are signed by a trusted certificate authority. The Apple Worldwide Developer Relations Certificate Authority issues the certificates you use to sign your software for Apple devices, allowing our systems to confirm that your software is delivered to users as intended and has not been modified.
The previous Apple Worldwide Developer Relations Certification Intermediate Certificate expired on February 14, 2016 and the renewed certificate must now be used when signing Apple Wallet Passes, push packages for Safari Push Notifications, Safari Extensions, and submissions to the App Store, Mac App Store, and App Store for Apple TV.
All developers should download and install the renewed certificate on their development systems and servers. All apps will remain available on the App Store for iOS, Mac, and Apple TV.
Since different methods can be used for validating receipts and delivering remote notifications, we recommend that you test your services to ensure no implementation-specific issues exist. Your apps may experience receipt verification failure if the receipt checking code makes incorrect assumptions about the certificate. Make sure that your code adheres to the Receipt Validation Programming Guide and resolve all receipt validation issues.
