I changed the version for my app in Xcode's "General" settings to be 0.3.0. I saved it and also looked into Info.plist, the version was also updated there. But when I archived it and looked for the version number in the generated .ipa file, I found it to be the version of the last archive I made for this project (which was 0.2.0). Thus I cannot upload the archive via Application Loader because the build with this version already exists in my iTunesConnect. How can I get Xcode to archive with the correct version number?
Remove device if your device connected with mac and build archive with generic device.
