Swift version: 5.2
If you want to convert a string to uppercase – that is, WHERE EVERY LETTER IS A CAPITAL LETTER – you should use the
uppercased() method of your string, like this:
let str = "Sunday, Monday, Happy Days" print(str.uppercased())
That code will print "SUNDAY, MONDAY, HAPPY DAYS" into the Xcode console.
