currently we are developing a flutter app with flutter SDK 1.20, we are sticking to version 1.20 due to some outdated packages we use.
after some googling we found that we still can open a debugging session on iOS simulators 10.3.1,
we are using Xcode 12.4 and when we try to add a new simulator and try to download a new OS version, we downloaded iOS simulator 10.3.1 and its added in Library/Developer/CoreSimulator/Profiles/Runtimes as iOS 10.3.simruntime
but unfortunately its not appearing when we choose to install an OS version on a new iOS simulator.
all we can choose are these simulators only...but 10.3.1 not showing:
how can we choose iOS simulator 10.3.1?
