After updating to Xcode 10.2: Invalid Toolchain error when trying to submit app to App Store [closed]

Question

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
Dear Developer,

We identified one or more issues with a recent submission for your app, "my app". Please correct the following issues, then upload again.

Invalid Toolchain - Your app was built with a beta version of Xcode or SDK. Apps submitted to the App Store must be built with the GM version of Xcode 9 and the SDK for iOS 11, tvOS 11, watchOS 4, or macOS 10.13 or later.

Best regards,

The App Store Team

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?

Answer 1

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 ...

Answer 2

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
