How to create an uppercase version of a String in SwiftUI?

Question

It is possible using Swift to create an uppercase version of a String with

let str = "Hello World!"
print(str.uppercased())

This code will print "HELLO WORLD!" into the Xcode console. But how do you create an uppercase of a String like the following using SwiftUI?

Text("Hello World!")

`Text("Hello World!".uppercased())` – rmaddy Jul 09 '19 at 04:10 — rmaddy, Jul 09 '19 at 04:10
This has nothing to do with swiftUI. – Umair Afzal Jul 09 '19 at 05:35 — Umair Afzal, Jul 09 '19 at 05:35

For those who want to use LocalizedStringKey. Since iOS 14 you can use .textCase(.uppercase) on Text.

Text(LocalizedStringKey("keyName"))
  .textCase(.uppercase)

You can do this simply in this way

Text("Hello World!".uppercased())

For LocalizedStringKey you can use this.

Text(LocalizedStringKey("keyName")).textCase(.uppercase)

What about if you are using a LocalizedStringKey? – Daniel Wood Mar 18 '20 at 14:54
@Maksymilian Tomczyk answer is better since it operates on the view side not the data side, also it can be composed into a Style, so even if you're not LocalizedStringKey then it's still the way to do it. – Lucas van Dongen Jun 17 '21 at 13:21
