Xcode 9.2: Invalid toolchain (while submitting to iTunes Connect)

I cannot submit my app to App Store with the latest stable version of Xcode.

Frequently happens with new versions of Xcode. Wait a day or so and it will be fixed. There is also an issue with downloading simulators from Xcode, cdn is missconfigured. Bad few days for apple.

So do I,have you solve the problem?
