You can also have this automatically opened in Xcode by `make open-hotspot-xcode-project` (but note that for repeated runs of this, `make open-hotspot-xcode-project-only` is greatly preferred).

Thanks for this great work.
IIRC, the copyright year for new files should show only the current year (2024) and does not include any earlier years. Correct?
The new files in this PR all have pair of years for new files. I think this is not the correct style.

Thank you for this useful feature. Creating the Xcode project and opening it work well.
Is there any help/doc for building JVM with XCode? I got this after opening the project in XCode and the first build try:
`Command PhaseScriptExecution failed with a nonzero exit code`
