Sample steps to manually update Xcode to latest 10.2 version (not necessary once the Xcode 10.2 GA version image has been released on CircleCI)

config.yml

version: 2
jobs:
  build:
    macos:
      xcode: "10.2.0"
    steps:
      - run:
          name: Update Xcode to latest 10.2 version
          command: |
            # Requires setting the XCODE_INSTALL_USER and XCODE_INSTALL_PASSWORD
            # environment variables

            xcodebuild -version
            sudo gem install xcode-install
            xcversion uninstall 10.2
            xcversion update
            xcversion install 10.2
            xcodebuild -version
          # Expect this to take at least 20 minutes

Is this something I have to do (I have them saved locally), or something CircleCi needs to fix?

Hi, @dai-cb
I got this same error message. If we set these Environment variables below, we could run the build.

• XCODE_INSTALL_USER (apple account)
• XCODE_INSTALL_PASSWORD (apple account)
• FASTLANE_SESSION

Looks like a great way to charge customers even more money by using up more machine time instead of enabling us to use proper macOS machine images
