在Swift中替换指示符之间的子字符串的更好方法？

import Foundation

func replaceSubstringBetweenIndicators(input: String, replacement: String) -> String {
    let pattern = "<(.*?)>"
    let regex = try! NSRegularExpression(pattern: pattern)
    let range = NSRange(location: 0, length: input.utf16.count)
    
    return regex.stringByReplacingMatches(in: input, options: [], range: range, withTemplate: replacement)
}

let inputString = "Hello <name>, welcome to <place>!"
let replacedString = replaceSubstringBetweenIndicators(input: inputString, replacement: "John Doe")

print(replacedString) // Output: "Hello John Doe, welcome to John Doe!"
