Why is iOS 12.0 not available as a deployment target on Xcode?

Hi,

I'm looking to update the minimum deployment target of my project to an iOS 12 version, and I'm wondering why Xcode doesn't provide iOS 12.0 as an option from the dropdowns - the earliest iOS 12 version it suggests is 12.1.

I can set it directly in the plist as iOS 12.0 but I'm getting the impression that Xcode doesn't want me to use 12.0.

Does anyone know why?
