XCode 13 work on 2014 Mac PowerBook?

Does XCode 13 work on 2014 Mac PowerBook?

PowerBook is an ancient brand name of Apple's and no product models named PowerBook are not out in 2014.

You should better check the exact model name with opening About This Mac:

The requirements of Xcode 13 RC is described in the release notes simply: Xcode 13 RC Release Notes

Xcode 13 RC requires a Mac running macOS 11.3 or later.

So generally, if you can upgrade your Mac to macOS 11.3 or later, you can run Xcode 13 RC on it.

What is the minimum available memory requirement? 

I could not find any clear documentations about memory requirements of recent Xcodes. But in my experience, 8GB is minimum, though it may not be enough when building some practical apps. Also you might need at least a few tens of GB of free disk space to test/run your apps.

All requirements here: h t t p s : / / xcodereleases.com

I assume you mean MacBookPro.

By experience, 8 GB is really a bare minimum, 16 should be more appropriate.

And don't forget to check available disk space before downloading (need about 80 GB free).
