I'm not sure we'll ever see a full xcode release for iPad unless something drastic happens with the way mobile operating systems work. On your desktop you are king, you have the freedom to delete most every file or install any utility to any directory. Apple does not want you to have that autonomy on your devices and made sure from the start that you are unable to do anything unless they approve. I just don't see a marriage between these two worlds anytime soon.
For a full release you are probably right, but a release that can only build iOS apps with swift and swiftui would be quite easy for them at this point.
