The new Swift Attributed String looks really neat, but is there a way to use it in UIKit or is it SwiftUI only? UITextViews take an NSAttributedString for their content, so I didn't know if there was a way I was missing for converting the AttributedString into an NSAttributedString.

NSAttributedString is given a new initializer taking an AttributedString.

convenience init(_ attrStr: AttributedString)

You can easily convert an AttributedString to an NSAttributedString:

        var astr = AttributedString("Hello, world!")
        if let range = astr.range(of: "world") {
            astr[range].font = .boldSystemFont(ofSize: 22)
        }
        label.attributedText = NSAttributedString(astr)

How do you convert NSAttributedString into AttributedString.

Also using an initialiser:

let ns: NSAttributedString = … something …
let a = try AttributedString(ns, including: \.uiKit)
