Could not run XCode 9.1 on MacOS 12 - ios

Question

I am trying to migrate my Swift 3 code to Swift 4 to meet the requirement of Apple. I downloaded Xcode 9.1, renamed it to Xcode9.1.app, and moved it to the Applications.
I tried to open it as explained in the following link: How can I run Xcode 12.5.1 on Monterey?. But it quits.
The quitting message is:

Problem
According to apple, macOS 12 requires you to use Xcode 13.

Solution
There is a way to install only the tool chain for Xcode 9, but not the
app itself. I'm not sure if Migration is possible through the command
line but it seems like the best solution.
