1, Xcode Export/upload error:your session has expired. Please log in
The answer I found on stack over flow:
A look at preference, sure enough:
Login again, OK.
2. Missing IOS distribution signing identity for.
My situation here is this:
Open the keychain and find some certificates inside it shows that this certificate issuer is invalid.
Workaround:
Open Keychain, delete login and system inside, all invalid certificates and expired certificates. It is important to note that expired certificates are not displayed by default, and you need to select "Show expired Certificates" in the Keychain's "display" menu to see them.
Then, update the WWDR system certificate.
Download the certificate address https://developer.apple.com/certificationauthority/AppleWWDRCA.cer download and then double-click Install.
Then, open the project, fix it, and then create a distribution certificate inside the preference. Everything OK.
3. No accounts with itunes connect access
During the upload process, log in to itunes Connect.
