Failure solution (Failed to locate or generate matching signing assets) and matchingsigning

 

The upload program may receive a message indicating that the Upload Failed.

Open your own key string and find that all certificates show that the certificate issuer is invalid.

The following situations occur:

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.

 

 

Cause & solution:

1. The reason is that we need to set up certificates in advance before uploading programs. Setting certificates involves applying for certificates from the certificate authority.

The issuer of the certificate is invalid.

 

2. At this time, we will go to our key string and select show above --> show expired certificates

3. Select Delete it and go

Https://developer.apple.com/certificationauthority/AppleWWDRCA.cer

Download a new certificate.

 

4. Double-click to run the task. However, some users may fail to add the task.

This is because you have not set the certificate permission.

If the problem persists, restart the key string.

 

 

5. After the certificate is successfully added, you can see that all the previous certificates are valid.

 

To sum up, simply put, the root certificate that you issue the developer certificate becomes invalid because it will expire on January 1, February 14, 2016.

The certificate you created earlier will expire. reinstall the root certificate.
