Basic Auth Request in Swift - swift

Question

Hey so I'm relatively new to Swift and I have successfully fetched data from a public API but there's another one that requires authentication. I do have an account and I've verified that the credentials work, however it's not clear to me how to write the POST request with Basic Auth
I see on the Wiki page for Basic Auth it says to configure the URL with the user & pass in it like this: https://Aladdin:OpenSesame#www.example.com/index.html, but this alone doesn't fix it so I'm not sure what else I need to do to configure this request. Any help would be appreciated!
struct Response: Codable {
var results: [Result]
}
struct Result: Codable {
var pool_system_type: String
}
struct WaterTestView: View {
#State private var results = [Result]()
var body: some View {
List(results, id: \.trackId) { result in
VStack(alignment: .leading) {
Text(result.pool_system_type)
}
}.onAppear(perform: loadData)
}
func loadData() {
guard let url = URL(string: "https://myemail#email.com:mypassword#biolabhydra.com/api/v3/water_tests") else {
print("Invalid URL")
return
}
let request = URLRequest(url: url)
URLSession.shared.dataTask(with: request) { data, response, error in
if let data = data {
if let decodedResponse = try? JSONDecoder().decode(Response.self, from: data) {
DispatchQueue.main.async {
results = decodedResponse.results
}
return
}
}
print("Fetch failed: \(error?.localizedDescription ?? "Unknown error")")
}.resume()
}
}

For basic auth you put the authentication data in an HTTP header field.
extension URLRequest {
mutating func setBasicAuth(username: String, password: String) {
let encodedAuthInfo = String(format: "%#:%#", username, password)
.data(using: String.Encoding.utf8)!
.base64EncodedString()
addValue("Basic \(encodedAuthInfo)", forHTTPHeaderField: "Authorization")
}
}
var request = URLRequest(url: URL(string: "https://www.awesome.com/")!)
request.setBasicAuth(username: "awesomeUser", password: "awesomePass")
request.httpMethod = "POST"
