We’ll stop selling our Code Editor app for iOS soon
&gt; The biggest technical hurdle is the inability to run external processes on iOS and iPadOS.<p>&gt; Apps on iOS and iPadOS must use Apple’s Javascript interpreter, JavaScriptCore.<p>Both of these really suck because they are policy, not technical, decisions. Even setting aside the arguments of whether JIT code is a security concern (it is not unless your security model is one where codesigning exists to prevent the addition of new native code) that you cannot spawn a new process, nor can you ship another JavaScript interpreter, is really unfortunate.<p>Allowing apps to spawn new processes is easy (I mean, just inherit sandboxing rules and resource limits…) and allows for a lot of new usecases, like robust crash reporting, web servers, privilege separation, and more. That Apple allows this on macOS and even uses it for its own apps on iOS just shows how useful this can be and how little it affects the security model of iOS.<p>Likewise, not allowing other JavaScript interpreters is just…annoying. Regardless of your opinions of JavaScriptCore, this is an unfair limitation on an already slanted playing field. Coupled with the fact that the JavaScriptCore interpreter (which the framework uses for anything you run in-process) is literally <i>designed</i> for low resource consumption instead of than performance makes this even more infuriating.
