However, I can see where it would be helpful (or even necessary) to run an emulator that mirrored a particular user’s hardware for an older version of iOS. I’m usually testing on newer iOS versions, with newer hardware and simulators. This finding will probably is not be a big issue for me, personally. I am not running Catalina yet, but when I upgrade I’ll definitely test this out to see if it’s a problem. macOS Catalina doesn’t allow any 32-bit apps to run, so presumably we would have to resort to using the iPhone 5s simulator (or higher), otherwise we would see the “‘App Name’ needs to be updated.” message, and the simulator just would not run.
In retrospect, this makes sense because iPhone 5 is a 32-bit device, and therefore so would its simulator counterpart. It surprised me at the time-but it probably shouldn’t have-that I got the notorious “‘App Name’ has not been optimized for your Mac and needs to be updated.” alert box.
The other evening, in the wake of a bit of nostalgia, I tested running an emulator project on an iPhone 5 simulator running iOS 10.3 in Xcode 11 (more on that in a future podcast episode).
