Xcode 7 error: "Missing iOS Distribution signing identity for ..."

I'm tried to upload my App to iTunes Connect resp. AppStore and get the following error:

Failed to locate or generate matching signing assets

Xcode attempted to locate or generate matching signing assets and failed to do so because of the following issues.

Missing iOS Distribution signing identity for ... Xcode can request one for you.

Before I setup a new development machine, exported the developer accounts via Xcode 7 from the old to the new machine.

What can I do to fix this?

From Apple -

Thanks for bringing this to the attention of the community and apologies for the issues you’ve been having. This issue stems from having a copy of the expired WWDR Intermediate certificate in both your System and Login keychains. To resolve the issue, you should first download and install the new WWDR intermediate certificate (by double-clicking on the file). Next, in the Keychain Access application, select the System keychain. Make sure to select “Show Expired Certificates” in the View menu and then delete the expired version of the Apple Worldwide Developer Relations Certificate Authority Intermediate certificate (expired on February 14, 2016). Your certificates should now appear as valid in Keychain Access and be available to Xcode for submissions to the App Store.



I also faced the same issue today. The following steps fixed my issue.

  1. Download https://developer.apple.com/certificationauthority/AppleWWDRCA.cer
  2. Double-click to install to Keychain.
  3. Then in Keychain, Select View -> "Show Expired Certificates" in Keychain app.
  4. It will list all the expired certifcates.
  5. Delete "Apple Worldwide Developer Relations Certificate Authority certificates" from "login" tab
  6. And also delete it from "System" tab.

Now you are ready go.



Apple has made following changes so download new certificate developer.apple.com

renewed certificate and place it as below screen shots .In the keychain as below screen shots click on system and then certificate. Delete the expired certificate . Then drag and drop the AppleWWDRCA.cer that you downloaded from above link

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 Apple Worldwide Developer Relations Certification Intermediate Certificate expires soon and we've issued a renewed certificate that must be included when signing all new Apple Wallet Passes, push packages for Safari Push Notifications, and Safari Extensions starting February 14, 2016.

While most developers and users will not be affected by the certificate change, we 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.

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 before February 14, 2016.

I imported the new Apple WWDR Certificate that expires in 2023, but I was still getting problems and my developer certificates were showing the invalid issuer error.

In keychain access, go to View -> Show Expired Certificates, then in your login keychain highlight the expired WWDR Certificate and delete it. I also had the same expired certificate in my System keychain, so I deleted it from there too.(Important)

After deleting the expired cert from the login and System keychains, I was able to build for Distribution again.



I removed old AppleWWDRCA, downloaded and installed AppleWWDRCA, but problem remained. I also, checked my distribution and development certificates from Keychain Access, and see below error;

"This certificate has an invalid issuer."

Then,

  1. I revoked both development and distribution certificates on member center.
  2. Re-created CSR file and add development and distribution certificates from zero, downloaded them, and installed.

This fixed certificate problem.

Since old certificates revoked, existing provisioning profiles become invalid. To fix this;

  1. On member center, opened provisioning profiles.
  2. Opened profile detail by clicking "Edit", checked certificate from the list, and clicked "Generate" button.
  3. Downloaded and installed both development and distribution profiles.

I hope this helps.



I kept running into the issue and saw that all my certs were invalidated -- oh no!

It turns out I never deleted the expired cert. It was not showing up for me, until I selected from Keychain Access application:

View->Show Expired Certificates

then

System->All Items

will finally display that gnarly expired cert. Delete that and retry from XCode will pick up the new valid certs.

Just make sure you search "All Items" in the Keychain Access app. The invalidated certs are a result of pointing to the expired certificate that has not been deleted yet.



The below process will solve the problem,

1: Open KeyChain access, and Delete "Apple world wide Developer relations certification authority" (Which expires on 14th Feb 2016) from both "Login" and "System" sections. If you can't find it, use “Show Expired Certificates” in the 'View' menu.

enter image description here

2: Now download https://developer.apple.com/certificationauthority/AppleWWDRCA.cer and double click the certificate to add it to Keychain access > certificates (which expires on 8th Feb 2023). Now the valid status of the certificates should turn green like below.

enter image description here

Once check the status.
