Apple Store no longer accepts apps builded with Xcode less than 9.
I know that Xcode 9 requires at least Mac OS X 10.12 (Sierra) but this answer gave me hope: https://stackoverflow.com/a/48692923/5321513
I've a MacBook A1181 (early 2009) and I've already tried to intercept and edit all the files I think are involved in checking the version with this terminal command:
grep "10.12" -R --include="Info.plist" /Applications/Xcode9.2.app 2>/dev/null
changing the parameter "Minimum system version" to "10.11.6" but also after restarting the OS I still obtain this message:
"OS X 10.11.6 is installed on your computer, the application requires OS X 10.12.1 or later
@Argus (https://stackoverflow.com/users/3611996/argus) and @laoyur (https://stackoverflow.com/users/6662165/laoyur) said that they were able to make Xcode work without updating macOS.
How can I make Xcode 9 work without upgrading macOS or anyway how can I submit iOS apps to the App Store with MacBook A1181 (until I get a new Mac)?

After having tried everything I found only the solution to force the upgrade of MacBook A1181 from MacOS X 10.11 (El Capitan) to MacOS X 10.12 (Sierra) with this tool (after shutting off SIP from Recovery Terminal with "csrutil disable"):

and installing manually Xcode 9.2, downloaded from
https://developer.apple.com/download/more/
Deploying of debug releases cannot be done from current releases of iTunes 12, so I found this method inside Xcode: Xcode => Window => Devices and Simulator
choosing the attached device and dragging the IPA into Installed Apps.
ps I had to apply also a patch for os system cache rebuilding and brightness control:

Thanks a lot to @dosdude1 for sharing all his knowledge about this problem.
