I mean you also need to buy a monitor and peripherals for a PC. Since they’re not built in you could find a 1080p monitor on Facebook marketplace locally for almost nothing. If you’re just doing iOS development the Mac mini should be fine.

Doing iOS development includes a whole other bundle of costs associated with it. $1000/yr if you want to even try to sell on the app store?

Those don’t need to be apple products - the mini has standard ports.
