fonts - 从 SwiftUI.Font 转换为 UIFont

Question

我有一个 UIViewRepresentable与 UITextView我想在 UITextView 上设置字体使用当前 Font来自 SwiftUI 环境。我只需要一个简单的初始化，如:

UIFont(_ swiftUIFont: Font)

但我找不到任何这样的东西。和 Font type 似乎没有任何信息我可以用来尝试实现一个。有人知道在两种字体表示之间进行转换的方法吗？

有点黑客但有效(做另一个方向留给读者作为练习)。

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
    }
}
