using POST API in ios using URLSession

Question

I'm learning IOS right now and I completely wrote same code with the tutorial. But I got an error like this

"2019-05-29 14:01:25.974883+0900 URLSessionJSONRequests[18165:938499] Task <0EC532CF-8CA6-42C9-9BD8-6D6E74BB9C06>.<10> finished with error - code: -1002"

My Code is this.

@IBAction func onPostTab(_ sender: UIButton) {

    let parameters = ["id":"[email protected]","pw":"1q2w3e4r"]

    guard let url = URL(string:"https//taky.co.kr/login/app_login") else{return}
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: [])else{
        return}
    request.httpBody = httpBody
    let session = URLSession.shared
    session.dataTask(with: request) { (data, response, error) in
        if let response = response {
            print(response)

        }
        if let data = data {
            do {
                let json = try JSONSerialization.jsonObject(with: data, options: [] )
                print(json)
            }catch{
                print(error)
            }
        }
    }.resume()


}

what is error code -1002?? I used placeholder API and it is still supported and I think the server is not the problem. Any reference or advice would be grateful!

Answer 1

Kindly check URL first you missed ':' after https.

Just replace your API End-point

https//taky.co.kr/login/app_login

With

https://taky.co.kr/login/app_login

After doing the above changes everything works fine.

API Response:
