Resolved for me. Message now shows correct version numbers and makes logical sense ITMS-90725: SDK Version Issue - This app was built with the iOS 16.0 SDK. Starting April 2023, all iOS apps submitted to the App Store must be built with the iOS 16.1 SDK or later, included in Xcode 14.1 or later.

We got the same message. For context, our app was built on Xcode 14.0.1, which doesn't seem to know about iOS > 16.0. We're planning on upgrading our build machines to Xcode 14.2 in the next few days (before the April deadline), which lists iOS 16.1 and 16.2 as valid minimum iOS versions. I think KCO_S has the right idea; it's a legitimate warning with unfortunate typos, which should read: ITMS-90725: SDK Version Issue - This app was built with the iOS 16.0 SDK. All iOS apps submitted to the App Store must be built with the iOS 16.1 SDK or later, included in Xcode 14.1 or later.
