Answer 1

i have this fonction to get firstname, lastname, number
func loadMemberProfil(){
let token = HPWSLoginManager.shared().saveSuccessResponse.token
let url = URL(string: "http://51.38.36.76:40/api/v1/profile")
var request = URLRequest(url: url!)
request.httpMethod = "GET"
request.addValue("Bearer \(token!)", forHTTPHeaderField: "Authorization")
//get information in token
URLSession.shared.dataTask(with: request) { (data, response, error) in
guard let data = data else { return }
do {
let json = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.mutableContainers) as! [String: AnyObject]
let sub = json["sub"] as! [String: AnyObject]
let firstName = sub["firstname"] as! String
let lastName = sub["lastname"] as! String
let number = sub["internationalFormat"] as! String
} catch {
print("error")
}
}.resume()
}
and in viewDidLoad() i want to display in this function
func initTableViewModel() {
let headerMenu = HPMenuHeaderViewModel.init(firstName: "...", lastName: "...", numberString: "...")
let tableViewModel = HPMenuViewModel(titlePage: "Menu", array: arrayCellModel, headerMenuViewModel: headerMenu)
self.tableViewModel = tableViewModel
}

You can achieve that by using Closures.
func loadMemberProfil(completion: ((_ sub : [String: AnyObject]) -> Void)?) {
let token = HPWSLoginManager.shared().saveSuccessResponse.token
let url = URL(string: "http://51.38.36.76:40/api/v1/profile")
var request = URLRequest(url: url!)
request.httpMethod = "GET"
request.addValue("Bearer \(token!)", forHTTPHeaderField: "Authorization")
//get information in token
URLSession.shared.dataTask(with: request) { (data, response, error) in
guard let data = data else { return }
do {
let json = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.mutableContainers) as! [String: AnyObject]
let sub = json["sub"] as! [String: AnyObject]
if completion != nil{
completion(sub)
}
} catch {
print("error")
}
}.resume()
}
Then call this method, where you want to set the last name
func initTableViewModel() {
self.loadMemberProfil { (sub) in
let headerMenu = HPMenuHeaderViewModel.init(firstName: "\(sub["firstname"])", lastName: "\(sub["lastname"])", numberString: "\(sub["internationalFormat"])")
let tableViewModel = HPMenuViewModel(titlePage: "Menu", array: arrayCellModel, headerMenuViewModel: headerMenu)
self.tableViewModel = tableViewModel
}
}
