IOS12 is an IOS that was previously thought to be the oldest,[1] but that was due to an $IOSVersion string for a specific part.

It is notable that IOS11 and IOS12 have much lower version numbers than IOS9 and IOS10; it is likely that v6 of this IOS was based on a very old version of IOS9, due to the IOS9 code getting messy. All future IOSes seem to stem from IOS11 and IOS12, so the IOS9 subtree was probably abandoned as opposed to numbering being restarted.

The SDK version built for IOS12 only supports 4:3 video.
