For all the iOS developers in here, Xcode 8.2.1 has a bug, when trying to sign an archive for store deployment, you will get an unexplained error saying "code signing fail", after for hours of frustration, tears and trial and error, I ended up signing it with xcode 7. I hope this helps

Thank you for this +1. Signing and publishing iOS apps is like shitting glass

@beercoder np, always happy to assist a fellow developer :)
It is a painful ugly process, each time I think I mastered all there is know about this shit another weird behaviour pops up and fucks my day, I spent fucking four hours trying to upload the version to iTunes connect.
Apple are a bunch of sadistic fucks.
