For Xcode 12.4 in the general setting tab, I set the minimum deployment target to iOS 9.0, however, after archiving and submitting the app the minimum version was 9.3. I tried this step more and more with no luck. each time the target forced to iOS 9.3
minimum iOS version
Xcode 12.4 proposes 9.0 or 9.2. Same for you ?
I compared with Xcode 12.1 which proposed
from 9.0, 9.1, 9.2, 9.3, …
whilst 11.3 which proposed all versions from 8.0 to 9.0, 9.1, 9.2, 9.3, 10…
So it seems they manage versions for reason, even if it"s surprising that some are skipped (9.1 and 9.3 in Xcode 12.4).
Finally, I would just accept the 9.3.
That's already very old iOS version, less than 1% use it now.
There may be a technical reason why archiver forces it.
