New variants of SF Pro were introduced for iOS 16, but I do not see an update to UIFont API to use them.
https://developer.apple.com/documentation/uikit/uifont
Another thread on here specified that it could be done through UIFontDescriptor, but it doesn't seem like thee that is the official way.
I really wish there is more information on this. I am wanting to use Expanded for my iOS update.
