(New posts asking this will be removed) Swift or Objective-C? if you don't know which language to choose. In recent years a number of iOS emulators have popped up for both Mac andManaging Devices and Corporate Data on iOS July 2018 5 Similar to creating a new version, the macOS app and tvOS app uses the same Apple ID (an app identifier).If you are looking to get started (iOS programming in general or some specific area), here are more relevant links for you: However, our development settled years ago. There is also dedicated subreddit for learning Objective-C: /r/learnobjectivecThere's too many to list them all, however here's a convenient link to all programming guides at apple.comTake note that this list is live and based on most frequent questions in posts will be updated with "quicklinks".Hello everyone, we present a working iOS App emulator for x86-based macOS here.In the year of 2021, Apple has unleashed ARM-based M1 chips for macintosh, making it much easier to run iOS Apps on PC-platform. Objective-C primer if you are new to the language and CocoaTouch frameworks.First, and most obviously, we face the problem of instruction translation between x86-64 and ARM. We abandoned the plan due to efficiency and compatibility problems.The are many puzzles to solve in order to run ARM-based iOS Apps on x86-based systems. Our emulator once has a Virtulbox-based shell in which macOS runs, so the whole system runs in Windows. We modified and hacked a lot on the simulator, making it possbile to run ARM-based commerical iOS Apps released in AppStore inside iOS Simulator. The iOS Simulator that comes with Xcode is capable of running iOS Apps based on x86 instructions, which means you must own the source.In order to do that, we hacked compiler of LLVM, scanning the whole SDK, generating all API parameter infomation, under which part of the ABI bridge may finally work.Nevertheless, the ABI includes not only c standards but also c++ ones. We have to build an ABI bridge for 2 instructions for they have different ABI standards. In the whole emulation, only the instructions within the iOS App is run in the mode of qemu JIT, while all the frameworks from Apple run natively on Intel CPU.
Iphone Ipad Emulator Mac AndManaging DevicesWe have 2 options: making patches on the binary or compiling altered source from Apple. Dyld, the dynamic linker from Apple, does not support this. We must keep 2 copies of libc++.dylib in the memory, one is x86-64-based, the other one is ARM-based. The frameworks code from Apple, who is x86-64-based, also uses C++. In order to solve the problem, we abondened the idea of ABI bridge on this part, seeking to provide an ARM-based libc++.dylib to the iOS App we are emulating.A new problem comes along with it. These changes are significantly hard to identify, making it impossible to do this part of ABI bridge. Use skype web app for macAs the work goes on, the complexity of the whole emulation system has gone far beyond our expectation. The most challenged among which, is the massive reverse engineering in order to make iOS App run flawlessly. For example, the acceleration and compatibility of Objective-C system, Metal API, hack of xnu by kernel extension. We have re-compiled the libunwind for that.In addition to thoese, there were still many more problems for running the emulator on x86-64-based macOS. When an exception is thrown, the original unwinding logic does not work properly in searching the correct exception handler. There are both x86-64 and ARM function frames in the stack.
