Build failing because of beta version of Xcode?

Hello,

Using fastlane I have a deployment set up on my master branch.

My entire lane goes through, right up to the uploading to iTunes Connect.
During this phase I receive the error

Return status of iTunes Transporter was 1: ERROR ITMS-90534: "Invalid Toolchain. New apps and app updates must be built with the public (GM) versions of Xcode 6 or later, macOS, and iOS SDK or later. Don't submit apps built with beta software including beta macOS builds."

My circle.yml file :

machine:
  xcode:
    version: 8.2.1
test:
  pre: 
    - gem install danger --version '~> 4.0'
    - gem update fastlane --no-ri --no-rdoc
    - mkdir -p $CIRCLE_TEST_REPORTS/xcode/
  override:
    - danger
    - fastlane ios test
deployment:
  testflight:
    branch: [master]
    commands:
      - fastlane ios deploy

Any help would be greatly appreciated !

Circle CI should update their Xcode versions. I’m waiting for a fix as well …

I’m seeing this as well. I’m able to specify “8.2” but it appears to be the beta version of 8.2, not the GM.

Xcode 8.2
Build version 8C30a

It should be 8C38, which was released on Dec. 12. So not all that long ago.
