@stroughtonsmith last i checked it was iOS 8 but that was a while ago (2020) - in *theory* as long as they've kept support for the built-in Swift runtime i wouldn't imagine that'd have changed...? (12.2 is the minimum so if they officially support 12.0 still then that shouldn't be an issue)

i wasn't able to get anything working on iOS 7 even though they said it worked
