We should be using the contents of Contents/Resources/LicenseInfo.plist within Xcode bundles to programatically determine whether an installed Xcode is a beta or not.

Xcode 9.4's looks like this, for example:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>licenseID</key>
    <string>EA1478</string>
    <key>licenseType</key>
    <string>Beta</string>
</dict>
</plist>
