Unlike its direct competitor, [[Android emulators|Android]], there are practically no usable emulators, as the official iOS SDK (macOS-only) only allows for running your own projects, i.e., they run code generated for an x86 target rather than ARM code as used by iOS. Some simulators Similar to most of the Android emulators, some emulators (e.g., [[BlackThunder]]) make uses two-step approach, making use of the simulator in the iOS SDK to run a few chosen iOS apps that are recompiled for x86. Unlike previous emulation trails, BlackThunder first loads a highly trimmed Hackintosh image via VirtualBox, which loads Xcode and an iOS simulator into it, then runs decompiled iOS apps recompiled for the x86 architecture. Appetize.io and other tools that claim to emulate iOS on a web browser are in reality just the iOS simulator in XCode wrapped around a cloud stream to the web browser, and like the iOS XCode simulator, need the source code to run. More recently, touchHLE managed to get a few older iPhone OS apps running by recreating some of iOS’s standard libraries and emulating just the iPhone’s CPU, and nearly the same time, QEMU-iOS got released and can successfully emulate iPhone OS 1.0 on an iPod Touch 1st generation, albeit with bugs.

Also tons of obsolete non-active iOS "emulator" exists, see [https://emulation.gametechwiki.com/index.php?title=IOS_emulators&oldid=72605 this page] for more.{| class="wikitable" style="text-align:center;width:100%"

HoweverAbout a year later, the same user managed to run iPhone OS 2 on an emulated iPod Touch 2G, some apps however internet connectivity is not figured out yet, and nobody has yet ran a 3rd party app via filesystem hacks as of now, as both networking and USB (iTunes) are unemulated and cannot be installed directly due to Apple DRM.

Many of the currently available '''"simulatorssolutions"''' only try recreating popular iOS apps (like browsers) in a PC application with no real emulation involved. Some notable [[Emulator scams|scams]] in such fashion are called '''iPadian''' or variations on the name, and are often '''malware'''. iPadian itself is not a real emulator and cannot actually emulate any iOS, iPadOS, or watchOS code and just use recreations that are limited in functionality and are not ports. “AIR iPhone” is also a simulator in Adobe Flash. Malware on Android also goes by the name “iEmu”, “Cider” and “Cycada”, based on the unfinished and unrelated unreleased projects of the same name, and is sometimes iOS launcher software that is possibly infected by malware. iOS emulators that aren't scams operate like XCode, where they cannot run non-development builds.

Your best bet, until touchHLE supports your 32-bit app, ARM macOS is able to be virtualized without an ARM Mac (for 64-bit), or a new emulation effort is ever started, is to hope that whatever iOS app you're interested in gets an Android port. This is very rare, especially for Japanese ones, as Android is perceived to be more open to piracy. That appears to be gradually changing lately and isn't of as much concern for non-gaming apps. However, in the U.S., the trend goes to iOS exclusively, including the Faves, Bloom, and the official ChatGPT apps getting iOS versions first, and a trend of users in Anglo-America discriminating against Android users, forcing them to switch to iOS also may contribute to the need for one.  ==External links==*[[Wikipedia:Comparison_of_mobile_operating_systems|Comparison of mobile operating systems]] (Wikipedia)*Reddit: [https://www.reddit.com/r/LegacyJailbreak/ r/LegacyJailbreak] (old devices) [https://www.reddit.com/r/LegacyJailbreak/ r/LegacyJailbreak] (new devices)
