How do I search and replace substrings efficiently?

Here is an example of how to search and replace substrings efficiently in Swift:


    // Sample function to search and replace substrings
    func searchAndReplace(original: String, search: String, replace: String) -> String {
        return original.replacingOccurrences(of: search, with: replace)
    }

    let text = "Hello, World!"
    let modifiedText = searchAndReplace(original: text, search: "World", replace: "Swift")
    print(modifiedText) // Output: Hello, Swift!
