We are currently facing an issue when attempting to deploy or update the iOS application provided by Salesforce. When signing the .ipa file shared periodically by Salesforce using Company’s Apple certificates, and attempting to upload it via Apple’s native Transporter application, we receive the following error message:
ITMS-90034: Missing or invalid signature – The bundle 'com.mysalesforce.mycommunity.[CODE]' at bundle path 'Payload/CommunitiesApp.app' is not signed using an Apple submission certificate.
We have strictly followed the steps described in the Salesforce document https://quip.com/yBxiAS29ZlvI
We have reviewed the Apple certificates. They are the same ones currently used for other active Company's applications — valid, unchanged, and not expired.
