Passing an Integer as a string in Swift to Express using Query Strings

I'm currently facing an issue with passing a query string from Swift to Express. I am sending [String: Any] data in the following manner:

let params = ["id": 1]

The function I'm sending it to is performing the following actions:

postString = ""
 
 for param in params {

     postString += "\(param.key)=\(content)"

     if params.count > 1 && i < params.count {
         postString += "&"
     }
 }

 let url = URL(string: "http://localhost:8080/api?" + postString)

 guard let requestUrl = url else { fatalError() }
 
 var request = URLRequest(url: requestUrl)
        request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")

 let (data, response) = try await URLSession.shared.data(for: request)

When transferring this to Express, I'm receiving all the parameters I'm passing, but they're being displayed as strings. Here is the request object:

  originalUrl: '/api?id=13',
  query: { id: '13' },

Is there a proper way to send an integer through the query string? Any assistance would be greatly appreciated. Thank you.

It's important to remember that query parameters do not include type information and are inherently treated as strings. Therefore, when working with these parameters, make sure to properly convert them using functions like `parseInt` to handle any potential errors.
