Yes, but even with the current latest SDK and latest Xcode, iOS 15 can be set as the minimum supported version.

We target older than that and it’s miserable.

Which, importantly means you can support devices back to the iPhone 6S that is a decade old at this point.

iOS 15 is like what, 4 years old? it's ridiculously short. (yeah, I know a device running ios 15 was also supported before being updated to that version, but it's still short)
