How to scale system font in SwiftUI to support Dynamic Type?

Question

In UIKit, I can change a UILabel's font size like this to support dynamic type using the system font:

UIFontMetrics.default.scaledFont(for: UIFont.systemFont(ofSize: 16))

Am I mistaken or is there no way to do such thing in SwiftUI? Can I only use the default font styles .title, etc. if I want to use the system font but also support Dynamic Type?

This solution from HackingWithSwift seems to only work with custom fonts, right?

Thanks in advance for any suggestions!

The following approach works (tested with Xcode 11.2.1 / iOS 13.2.2)

var body: some View {
    Text("Hello, World!") // direct text .font
        .font(Font.system(size: UIFontMetrics.default.scaledValue(for: 16)))
}

as well as for view-based modifier

VStack {
    Text("Hello, World!")
}
.font(Font.system(size: UIFontMetrics.default.scaledValue(for: 16)))
