Why is RoundCodes only compatible with iOS 13.0+?

[mrousavy]

The README states that RoundCodes is written in Swift 5, requires Xcode 11 and is compatible with iOS 13.0+. Does it not work below iOS 13? Which APIs do you use that are not available on, say, iOS 11?

@mrousavy I think there are no APIs requiring iOS 13. Will add support for iOS 10.
