Encountering the “Missing iOS Distribution signing identity” error in Xcode can be a stumbling block when attempting to upload your app to the App Store. This guide will walk you through the steps to resolve this issue effectively.

Understanding the Problem

The error typically arises when Xcode is unable to locate or generate the necessary signing assets due to expired certificates. Specifically, the issue often involves the expired Apple Worldwide Developer Relations (WWDR) Intermediate Certificate.

Step-by-Step Solution

1. Download the New WWDR Certificate: Visit Apple’s Developer website to download the new WWDR intermediate certificate.
2. Install the Certificate: Double-click the downloaded certificate to install it via Keychain Access.
3. Show Expired Certificates: Open Keychain Access, navigate to the ‘View’ menu, and select “Show Expired Certificates” to reveal expired certificates.
4. Remove Expired Certificates: Locate and delete the expired Apple Worldwide Developer Relations Certificate Authority Intermediate certificate from both the ‘Login’ and ‘System’ keychains.
5. Verify Certificates: Ensure that your certificates now appear as valid in Keychain Access.

Following these steps should resolve the error, allowing Xcode to utilize the valid certificates for app submission to the App Store.

Additional Considerations

If the above steps do not resolve your issue, consider the following:

• Ensure all developer and distribution certificates are up to date.
• Revoke and recreate certificates if necessary, especially if they show as invalid.
• Update provisioning profiles to reflect any changes in your certificates.
