A bit of a hack but works (doing the other direction is left as an exercise to the reader).
extension UIFont {
class func preferredFont(from font: Font) -> UIFont {
let uiFont: UIFont
switch font {
case .largeTitle:
uiFont = UIFont.preferredFont(forTextStyle: .largeTitle)
case .title:
uiFont = UIFont.preferredFont(forTextStyle: .title1)
case .title2:
uiFont = UIFont.preferredFont(forTextStyle: .title2)
case .title3:
uiFont = UIFont.preferredFont(forTextStyle: .title3)
case .headline:
uiFont = UIFont.preferredFont(forTextStyle: .headline)
case .subheadline:
uiFont = UIFont.preferredFont(forTextStyle: .subheadline)
case .callout:
uiFont = UIFont.preferredFont(forTextStyle: .callout)
case .caption:
uiFont = UIFont.preferredFont(forTextStyle: .caption1)
case .caption2:
uiFont = UIFont.preferredFont(forTextStyle: .caption2)
case .footnote:
uiFont = UIFont.preferredFont(forTextStyle: .footnote)
case .body:
fallthrough
default:
uiFont = UIFont.preferredFont(forTextStyle: .body)
}
return uiFont
}
}
