If I install Catalina on unsupported models of MacBook Pro through [a patcher](http://dosdude1.com/catalina/), will there be any (certification or other) problem while compiling for iOS through Xcode 12?

I wouldn’t have thought so DG, but maybe keep a separate boot drive without it just in case?

I know it will work fine, and some of the older models like i7 15" 2011, or i7, 15" 2012 have 2.0 GHz or above, quad-core processors and are quite performant machines and will compile on Xcode just fine, but I don’t know if there will occurs some certification related error or not.

I’m not sure (I do remb submitting my app was [a bit of a pain](https://astonj.com/invalid-signature-error-on-submitting-app-to-the-mac-app-store)) but again, I wouldn’t have thought so …I am sure I’ve seen YouTube videos of iOS devs using hackintoshes (but don’t quote me on that!)

Yes, you’re right.  
Those two links you provided in that post are already dead.
