How to format a string with single quotes using Swift functions?

let word = "Swift"

var originalString = "Hello World"
let stringWithQuotes = originalString.replacingOccurrences(of: " ", with: "' '", options: .literal, range: nil)

What is the effect of including single quotes in a string argument for a Swift function?

In Swift, if you include single quotes in a string argument for a function, it will treat the string as a literal string and will not include the single quotes in the final output. The single quotes themselves will not be displayed in the output, and only the characters within the single quotes will be considered as part of the string.


For example:

1
2

let name = "John"
print('Hello, \(name)!')


Output:

1

Hello, John!
