I had submission errors today when using Xcode 4.0.3 and the zip & Application Loader approach. It submitted fine from AL and then I got “invalid binary” in iTunes Connect (tried twice) even though that has always worked fine, and with this same app 2 weeks ago. I didn’t get any information about what was invalid.
I noticed that Xcode 4.0.3 isn’t on the main download page anymore, so I downloaded and installed Xcode 4.1 and did the Archive, Validate, Submit approach (no other changes). It validated fine and is now “Waiting for Review.”
Feels like something changed today. Maybe Xcode 4.1 is required now?
