A read similar questions but related to Beta version of Xcode, my doubt is wired to the last version of Xcode (4.3) that seems to be too buggy at the moment!
I rather use Xcode 4.2 but I'm not sure I can submit apps with this version! Is the last version of Xcode a requirement to send app to Apple ? Where I can read something about that ? Apple documentation didn't help me.
You can still submit apps with xCode 4.2 . Only beta version of xCode cannot submit apps.
