在Swift中使用regexp更快地替换大量字符串

import Foundation

let inputString = "Hello, my email is example@example.com and my phone number is 123-456-7890."
let emailPattern = "[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}"
let phonePattern = "\\d{3}-\\d{3}-\\d{4}"

func replacePattern(in input: String, pattern: String, with replacement: String) -> String {
    do {
        let regex = try NSRegularExpression(pattern: pattern)
        let range = NSRange(location: 0, length: input.utf16.count)
        let result = regex.stringByReplacingMatches(in: input, options: [], range: range, withTemplate: replacement)
        return result
    } catch {
        print("Invalid regex: \(error.localizedDescription)")
        return input
    }
}

let replacedEmail = replacePattern(in: inputString, pattern: emailPattern, with: "[REDACTED]")
let replacedPhone = replacePattern(in: inputString, pattern: phonePattern, with: "[REDACTED]")

print(replacedEmail) // "Hello, my email is [REDACTED] and my phone number is 123-456-7890."
print(replacedPhone) // "Hello, my email is example@example.com and my phone number is [REDACTED]."
