I have an older Mac Mini (mid 2011, 2.3GHz Intel Core i5). The latest os for this Mac is High Sierra (10.13.6) and latest Xcode is 10.1. I have iOS simulator 12.1 now within Xcode. But I would like to run simulator 12.3.1 (latest production). I was not able tu update the 12.1 to never version via the official setting (update button does nothing).
Is it possible to run newest simulator somehow? If not possible officially, is there a workaround to run iOS sim 12.3.1 on this old Mac?
