Xcode_12.0.0.app missing from macos-10.15

Without warning, the /Applications/Xcode_12.0.0.app/Contents/Developer directory disappeared from the macos-10.15 hosted agent, breaking my actions. The Xcode_11.0.0.app version still exists, why wouldn’t Xcode_12.0.0.app be retained?

@ssrobins,

The default version of Xcode on the GitHub-hosted macOS runners had been changed to Xcode 12.0.1 (path: /Applications/Xcode_12.app) since October, 20. More details, see here.

Xcode 12.0.0 is no longer pre-installed on the GitHub-hosted macOS runners. More details, see here.

In addition, Xcode 11.0, 11.1, 11.4.0 will be deprecated on the GitHub-hosted macOS runners from November, 5. More details, see here.
