Source code: Notes: - this is pretty much a PoC as it’s vibecoded in 3 days (with guidance and knowledge from Sim26Booter etc), you need to set up simulator runtime and sign yourself, as app doesn’t include builtin tools to patch and sign binaries - limited shell support: no fork() implemented so only fish shell will work - yeah this probably can be expanded to tvOS, watchOS, visionOS? simulators etc but I’m too lazy to try now - LiveContainer is not yet supported due to LiveProcess needing no ObjC usage until handoff to dyld_sim

You can switch between iPhone or iPad models on the same simulator container. Currently it only uses 1 container. Here is simulator details switched to iPhone 8+ and 15PM

No that’s completely different thing. They have what looks like a real SpringBoard skin but has fake app launch animation (spring) and is based on LiveContainer multitask. LiveSimBooter boots a whole iOS simulator, includes starting from simulator’s launchd and real daemons.
