Apple’s Worldwide Developer Relations Intermediate Certification expires today

Apple’s Worldwide Developer Relations Intermediate Certification expires today. Developers who provide passes for Apple Wallet, deliver Safari Push Notifications, or create Safari Extensions need to download the renewed certificate, and take the action described here.

Apple says that, to help protect customers and developers, it requires 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 developers use to sign their software for Apple devices, allowing their systems to confirm that your software is delivered to users as intended and hasn’t been modified.

Apple says that, while most developers and users, won’t be affected by the certificate change, they recommend that all developers download and install the renewed certificate on their development systems and servers as a best practice. All apps will remain available on the App Store for iOS, Mac, and Apple TV.
