    you can remove unwanted characters by adapting the parameters right before passing it into the parser like:

    let adaptedParams = params.reduce(into: [String: String]()) { $0[$1.key] = $1.value.joined(separator: ",") }

    "…How to remove %22%5D from url? ". Try this:

     let ids = "%5B%4566abef1c-4462-4g62-bcc5-5ae10547104c%22,%20%1256efcf8c-6977-430d-b3ec-4ae80547101c%22%5D"
 let cleanUrl = ids.replacingOccurrences(of: "%22%5D", with: "")
 print("n---> cleanUrl: (cleanUrl) n")

    You can also remove all percent encoding using this:

       if let cleanUrl = ids.replacingOccurrences(of: "%5B", with: "") // [
    .replacingOccurrences(of: "%5D", with: "")  // ]
    .replacingOccurrences(of: "%22", with: "")  // "
    .removingPercentEncoding {  // other encoding
    
    print("n---> cleanUrl: (cleanUrl) n")
}

    There is an API to remove the percent encoding

    let string = "ids=%5B%4566abef1c-4462-4g62-bcc5-5ae10547104c%22,%20%1256efcf8c-6977-430d-b3ec-4ae80547101c%22%5D"
let cleanedString = string.removingPercentEncoding

    However if you need to extract the UUIDs you can do it with Regular Expression

    func extractUUID(from string : String) -> [String]
{
    let pattern = "[0-9a-f]{10}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}"
    let regex = try! NSRegularExpression(pattern: pattern)
    let matches = regex.matches(in: string, range: NSRange(string.startIndex..., in: string))
    return matches.map { match -> String in
        let range = Range(match.range, in: string)!
        return String(string[range])
    }
}

let uuids = extractUUID(from: "ids=%5B%4566abef1c-4462-4g62-bcc5-5ae10547104c%22,%20%1256efcf8c-6977-430d-b3ec-4ae80547101c%22%5D")
print(uuids)

    Note: the g in the first UUID is an invalid character
