I did an update on my Mac recently that made me re-install Xcode and Cocoapods. I tried to archive the latest version of my iOS app and I specify it as "1.28" under the "General" tab and in the "Identity" section. When it is done archiving and the Organiser pops up it shows the app as version 1.0.
I've been told I should try cleaning my build folder. I did that under Product --> Clean Build Folder but that doesn't help.
