Almost booting an iOS kernel in QEMU

&gt;..but XNU is now open source.<p>Well XNU has always been &#x27;open-source&#x27; [1] for some time on Intel machines but its just that ARM support remained closed (until 2017) which is why the darwin-on-arm [2] project existed. But I&#x27;m assuming that the OP means that the ARM64 code was recently open-sourced in the XNU sources[3] making a possible open-source ARM port much simpler. I still find it quite interesting to see some regained attempts in emulating iOS; with Corellium being the furthest at doing this.<p>[1] (<a href="https:&#x2F;&#x2F;opensource.apple.com" rel="nofollow">https:&#x2F;&#x2F;opensource.apple.com</a>)<p>[2] (<a href="https:&#x2F;&#x2F;github.com&#x2F;darwin-on-arm&#x2F;xnu" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;darwin-on-arm&#x2F;xnu</a>)<p>[3] (<a href="https:&#x2F;&#x2F;github.com&#x2F;apple&#x2F;darwin-xnu&#x2F;search?p=5&amp;q=ARM64&amp;unscoped_q=ARM64" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;apple&#x2F;darwin-xnu&#x2F;search?p=5&amp;q=ARM64&amp;unsco...</a>)

In a way, it seems strange nobody made a full-blown iPhone&#x2F;iPad iOS emulator yet. Not a simulator like the one Apple makes, but an emulator like for game systems. I would guess the amount of information available about iPhone hardware and software would make it much easier to emulate than e.g. a gamecube, Wii, PS3, etc, especially for older models. Such an emulator could obviously be used for piracy, but could also be an intersting tool for a homebrew scene (custom firmware, developing iOS apps on Linux &amp; Windows, etc.<p>Is there a practical reason why this would be hard or impossible? Or is it just for fear of Apple&#x27;s lawyers?

Interesting. I would love virtual iPhones. For testing apps, anonymously. But I doubt that I&#x27;d get an invite from Corellium, either :(
