9 sourcesInteresting. I’m going to have to try this.
This GitHub issue has more info:
https://github.com/utmapp/UTM/issues/397
In iSH ShellUTM no longer works on iOS 14 without a jailbreak. It used shenanigans[0] to cause the process to be entitled to JIT, and the shenanigans no longer work.
0: https://github.com/utmapp/UTM/blob/1feb721a9474255bd112f9e42...
In iSH ShellIt's running via https://github.com/utmapp/UTM, a qemu-based VM manager for iOS.
In Mac OS X Leopard and Xcode on iPad ProOnce iOS has the ability to sign its own apps, the sky is the limit. In fact, we're getting pretty close to this even without Apple's help. UTM can boot Windows 10 using a whacky JIT hack to get QEMU's TCG working for (slow) x86 emulation. It won't be long until someone boots Xcode and compiles a simple app (though it would probably take hours!). https://github.com/utmapp/UTM. On the other hand, many smart people have started to port other languages, such as porting the Python interpreter (https://github.com/holzschu/python3_ios) and C compilers (https://github.com/ColdGrub1384/SeeLess). See the LibTerm project (https://github.com/ColdGrub1384/LibTerm). I can already see someone creating a sandboxed mini-OS with the ability to spawn and manage processes just like a Linux terminal by cheating iOS's Thread API.
However, your forum post says
Read the rest
you believe Apple wants to take the power of the ability to locally compile and sign away from developers. This is unlikely for a number of reasons, one of which is completely breaking all games built using non-SceneKit workflows (basically all of them) along with other apps that depend on outside compilers.
It does! https://github.com/utmapp/UTM
In Xnu-QEMU-Arm64: iOS on QEMUthere's a Qemu implementation that now runs on iOS, and with services like AWS Cloud9 you can get away with developing on an ipad only setup, at least for most webdevs. Sooner than later someone is going to be able to run android on this: https://github.com/utmapp/UTM
and then the gates will open to ARM heaven, once developers find a way to do their jobs on an ipad the rest of the industries follow
In ARMed mac: not again or for real this time?This appears to be an expanded description of a long-known technique, described by the author on HN years ago: https://news.ycombinator.com/item?id=18431524
It's also mentioned in the source code of UTM, a virtual machine app for iOS: https://github.com/utmapp/UTM/blob/ac89c106ecf9c765ea47bfe04...
