Change font size base on device

Question

is there any way to understand which type of Device the user is using.

I would like to use it in order to change the font size for the iPhone8 , if device == "iPhone8" { use Textfontsize 20 } else { use 10}

thanks a lot

Damiano,

Changing the font size based on the device isn't a good plan, what happens when Apple launch a new device. What does your user who uses accessibility and wants to make the font larger do? Maybe you have a user who wants small fonts cause he is using a 12inch iPad in dual screen mode.

Use dynamic fonts, and let the user choose the size they like :) Here is cut'n'paste from an article on that very same subject.

https://www.hackingwithswift.com/quick-start/swiftui/how-to-use-dynamic-type-with-a-custom-font

@available(iOS 13, macCatalyst 13, tvOS 13, watchOS 6, *)
struct ScaledFont: ViewModifier {
@Environment(\.sizeCategory) var sizeCategory
var name: String
var size: CGFloat

func body(content: Content) -> some View {
   let scaledSize = UIFontMetrics.default.scaledValue(for: size)
    return content.font(.custom(name, size: scaledSize))
}
}

@available(iOS 13, macCatalyst 13, tvOS 13, watchOS 6, *)
extension View {
func scaledFont(name: String, size: CGFloat) -> some View {
    return self.modifier(ScaledFont(name: name, size: size))
}
}

struct ContentView: View {
var body: some View {
    List {
        Text("Hello World")
        Text("Hello World")
            .scaledFont(name: "Georgia", size: 12)
    }
  }
}
