Getting a SSL error code -1200 while trying to integrate a post API using Alamofire in swift

Question

I am trying to integrate a POST api in my project using ALAMOFIRE, but there is an error that I am getting which prints "An SSL error has occurred and a secure connection to the server cannot be made." in my console. The entire error that is being printed in my console is as below:-

There are several files that constitute to my project as follows:-

1. Model:-

   import Foundation

   struct RegisterModel: Encodable { let email: String let firstname: String let lastname: String let password: String }

2. View

import SwiftUI

struct SignupFormView: View {
    @StateObject private var formModel = FormViewModel()
    var body: some View {
        ZStack {
            VStack {
                LogoImage()
                PrimarytextStyle(title: "Create an Account")
                Group{
                    TextField("Email address", text: $formModel.textEmail, onEditingChanged: {  formModel.handleEditChanged($0, formModel: formModel) })
                    if !formModel.isEmailValid {
                        InvalidEmailView()
                    }
                    TextField("First name", text: $formModel.firstname)

                        .padding(.bottom)
                    TextField("Mobile Phone number (optional)", text: $formModel.phone)
                        .padding(.bottom)
                    SecureField("Create Password", text: $formModel.Password)
                    Text(formModel.passwordPrompt)
                        .foregroundColor(.red)
                        .font(.system(size: 10))
                        .frame(maxWidth: .infinity, alignment: .leading)
                    SecureField("Confirm Password", text: $formModel.ConfirmPassword)

                }
                .textFieldStyle(.roundedBorder)
                .frame(width: 360)
                .autocapitalization(.none)
        
            Button {
                if formModel.isEmailValid && formModel.isPasswordCriteriaValid && formModel.isConfirmPasswordValid {

                  let register = RegisterModel(email: formModel.textEmail, firstname: formModel.firstname, lastname: formModel.lastname, password: formModel.Password)
                  APIManager.shareInstance.callingRegisterAPI(register: register)

            } label: {
                PrimaryButton(title: "CREATE AN ACCOUNT", bgcolor: Color.blue, textcolor: Color.white)
            }
            .opacity(formModel.canCreateAccount ? 1 : 0.6)

            })
            .navigationBarHidden(true)
            .navigationBarBackButtonHidden(true)
        }
        .padding(.bottom, 120)

}

}

struct SignupFormView_Previews: PreviewProvider {
    static var previews: some View {
        SignupFormView()
        
    }

3. ViewModel

   import Foundation import Combine

   class FormViewModel: ObservableObject {

    @Published var Password = ""
    @Published var ConfirmPassword = ""
    @Published var firstname = ""
    @Published var lastname = ""

    @Published var isEmailValid : Bool   = true
   
    func textFieldValidatorEmail(_ string: String) -> Bool {
        if string.count > 100 {

        let emailPredicate = NSPredicate(format:"SELF MATCHES %@", emailFormat)
        return emailPredicate.evaluate(with: string)
    }
   
    let passwordPredicate = NSPredicate(format: "SELF MATCHES %@", "^(?=.*[A-Za-z])(?=.*\\d)(?=.*[@$!%*#?&])[A-Za-z\\d@$!%*#?&]{8,}$")

            .assign(to: \.isPasswordCriteriaValid, on: self)
            .store(in: &cancellableSet)
   
        Publishers.CombineLatest($Password , $ConfirmPassword)
            .map { Password , ConfirmPassword in

        Publishers.CombineLatest3($isEmailValid , $isPasswordCriteriaValid, $isConfirmPasswordValid)
            .map { isEmailValid , isPasswordCriteriaValid, isConfirmPasswordValid in
                return ( isEmailValid && isPasswordCriteriaValid && isConfirmPasswordValid)
            }
            .assign(to: \.canCreateAccount, on: self)
            .store(in: &cancellableSet)
   
    }
   
   
   
    var confirmPwPrompt: String {
        isConfirmPasswordValid ? "" : "Password does not match"
    }

        lastname = ""
        phone = ""
    }
   
   
   
    func handleEditChanged(_ isChanged: Bool, formModel: FormViewModel)
    {
        if !isChanged {
            if formModel.textFieldValidatorEmail(formModel.textEmail) {
                formModel.isEmailValid = true
            } else {
                formModel.isEmailValid = false
                formModel.textEmail = ""
            }
        }
    }
   

   }

4. API Manager

   import Foundation import Alamofire

    class APIManager {
      static let shareInstance = APIManager()
   
      func callingRegisterAPI(register: RegisterModel) {
        let headers: HTTPHeaders = [
          .contentType("application/json")
        ]
        AF.request("https://b2c-api.digital.com/customerservice/customers/createCustomer", method: .post, parameters: register, encoder: JSONParameterEncoder.default, headers: headers).response { response in
          debugPrint(response)
          switch response.result {
          case .success(let data):
            do {
              let json = try JSONSerialization.jsonObject(with: data!, options: [])
              print(json)
            } catch {
   
            }
          case .failure(let err):
            print(err.localizedDescription)
          }
        }
      }
    }
   

Can someone please provide the solution on how to resolve it I am new to swift.

Also I am getting a Fatal error: Unexpectedly found nil while unwrapping an Optional value in API Manager code inside do{} block over data!.

Answer 1

So we need to pass the authorization header too in the api. So it would be like

let headers: HTTPHeaders = [
      .contentType("application/json"), .authorization(bearerToken: "Bearer eyJhbGciOiJIUzUxMiJ9.eyJqdGkiOiJzb2Z0dGVrSldUIiwic3ViIjoiZGV2IiwiYXV0aG9yaXRpZXMiOlsiUk9MRV9VU0VSIl0sImlhdCI6MTY2NzQ3Njg3OCwiZXhwIjoxNjY3NTYzMjc4fQ.t7rsskdb7ADELZCWxTZnq2mBLuJcsvSqOFKn0i54m2F_IKMl7zOjSgbyadDIAgNd9tQfEISsZ-g7uq-ssVGeIQ")
    ]

So it will resolve the error. the authorization token is unique and needs to be generated for one's own.
