SInce upgrading to Xcode 7.3, I can no longer submit IAP content using Application Loader. I was able to upload content before upgrading to Xcode 7.3. Now I need to update my IAP content and I'm getting this error in Application Loader:
ERROR ITMS-10001: "Multiple items in this package use the same vendor ID. Use unique vendor IDs for the items [software_assets] and resubmit the package."
Is anyone else seeing this error?
UPDATE:
I downgraded to Xcode 7.2.1 and am still seeing this error. It appears that the problem is on the iTunes Connect side.
