Sorry but there are no such “EMULATORS” like that of Bluestacks for the iOS environment. In my case, I was running Yosemite on my Mac Pro (mid-2006, the first generation), and the latest as of now requires El Captain, which the guy who made the modified Yosemite install image hasn’t made one for El Cap. The only problem with Xcode is that when a new version of macOS comes out, Xcode tends to quickly drop support for the version you are currently running. Running a thing we Mac users would like to call xCode, which so happens to include a Device Simulator, which can simulate anything from the latest iPhone to the latest AppleTV. Which is the best iOS emulator for Windows pc?
