can't on latest ipad os, at least not without a jailbreak first? at least as far as I can tell, from UTM's own documentation. wish it was a developer option at least.
You can side load it using a developer account without jailbreaking.
Seems like with iOS 14+, and as of writing it seems like we're on iOS 17, it needs to be jailbroken? Do Jitterbug, Jitstreamer, AltJIT, work for developer accounts?
