I have experienced similar problem to this (error 434 when uploading an archive to App Store with Xcode 8)
Strange Errors on Archive Validation
so I switched to the Application Loader and got following error:
I double-checked on everything regarding the provisioning stuff, code signing etc. Also, I did all usual troubleshooting steps like clean build, deleting derived data, restarting etc. Still no success. Anyone has dealt with it with success?
