Xcode automatically updated to version 10.2 today. As well I wanted to submit a new version of my App Store today. After submitting I got the following email:
App Store Connect

Whats the problem? Xcode 10.2 isn't in beta anymore as I never downloaded the beta version. Am I doing something wrong or is this apples fault?
Seems like Apple has fixed it!
Pushed “Submit for review” again, without any changes, with the same binary.
And the build stays in Waiting for Review status for a few hours already.
Found an entry from Apple Developer Forums that I am not the only one. No solution suggested there except waiting so that I will just wait ...
FYI, I've tried this and it doesn't work.
It seems that Apple was bit "careless" previously, by not updating their backend to accept the latest XCode GM version. See this for example.
Unfortunately, it seems to me that the only possible solutions are either waiting for Apple to fix it or downgrading your XCode version to 10.1
I think this fixed it for me.
Open the project in Xcode then click on the most top level item in the Project Navigator. Open the right pane and under Project Format switch it from Xcode 9.3-compatible to Xcode 10.0-compatible. Increase the build number by one then upload the app again through Archive and resubmit the new build.
