I've been struggling with this for the past week and can't find a single solution that works. I'm updating my app and when I validate it I get the error:
application failed codesign verification. the signature was invalid, or it was not sign with an Apple submission certificate
When I first made the app I was running Xcode 3.x, currently it's 4.1. I'm using the same distribution profile, same app ID, edited the archive scheme to use distribution.
Someone please please please help. This is killing me
