I believe Apple removed support for iOS 7 in the latest Xcode. This means the simulator was removed to. I think it is their way of getting people to only develop modern apps so consumers buy fresh devices.
I would have liked to do testing on iOS 7 as well since there are a ton of iPhone 4 devices still floating around.
Yes you’re right, no iPhone4 in xCode.
But actually I managed to download from xCode iOS 7.1 version for all platforms. Now in xCode I got two emulators for each device. Any idea how can I specify in ionic-cli which version I wan to run?
