Xcode13 inline Documentation Quick Help not displaying information?

Symbol Documentation in Your Source Files - when I highlight the function name addStrings and use the Option-click, it fails to display anything. When I click on the variable, it does display. Is this a failure of Xcode13 or am I missing something I need to set up in the environment first? Thanks all... (P.S. yep I'm a newbie, so this post might not be in a format desired....). But the doc looks like it should work?

import Foundation

/// addStrings function

///

///  This function concatinates two strings returning the combined single string

///

/// - Parameters:

///   - string1: First String

///   - string2: Second String

/// - Returns: FirstString + SecondString

///

func addStrings ( _ string1: String, _ string2: String) -> String {

    let resultString = string1 + string2

    return resultString

}

let string1 = "Document Quck Help from Option-click not working? "

let string2 = "Does not display, am I missing something"

let newstring = addStrings(string1, string2)

print(newstring)

I tested in playgrounds, it works perfectly.

I tested in a project, it works as well.

All tests with Xcode 13.0

Which version do you use ?
