xcodebuild fails with #Preview macro with Xcode 15.0

I noticed that in Xcode 15.0, xcodebuild command to archive the app fails unless I remove the #Preview macro from the app.

$ xcodebuild archive -scheme <Your Scheme> -sdk iphoneos -allowProvisioningUpdates -archivePath build.xcarchive

and the error is:

{
  "kind": "finished",
  "name": "compile",
  "pid": 42409,
  "output": "<unknown>:0: warning: compiler plugin not loaded: '/Applications/Xcode-15.0.0-Release.Candidate.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/swift-plugin-server; fai

}
** ARCHIVE FAILED **

How to reproduce:

  1. Create a brand new app project with Xcode 15.0 RC
  2. Run the above command

If I comment out the default #Preview statement in the ContentView.swift, the same command passes flawlessly. What am I missing?
