How do you display JSON API data in a table view? - ios

Question

I am not able to display the JSON data in my table view. I don't know why. I tried to get the JSON data, but I am not able to display it on screen in a table format.
This is the model:
class PastTripsVC: UIViewController {
var past = [PastRide]()
#IBOutlet weak var mTable: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
let nibCell = UINib(nibName: "PastTableView", bundle: nil)
mTable.register(nibCell, forCellReuseIdentifier: "cell")
apiCalling()
}
func apiCalling(){
if let url = URL(string: "https://pincood.com/pincood/public/api/user/trips") {
var request = URLRequest(url: url)
request.allHTTPHeaderFields = [
"Content-Type": "application/json",
"Session": "fb4e7f9b-0f31-4709-",
"AUthorization":"<some key>"
]
URLSession.shared.dataTask(with: request) { (data, response, error) in
guard error == nil else { return }
guard let data = data else { return }
do{
let codabledata = try JSONDecoder().decode([PastRide].self, from: data)
print(codabledata)
DispatchQueue.main.async {
self.past = codabledata
self.mTable.reloadData()
}
} catch {
print(error)
}
}.resume()
}
}
In the extension we try:
extension PastTripsVC : UITableViewDelegate, UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return past.count
print(past.count)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! PastTableView
cell.usernm.text = past[indexPath.row].provider.firstName
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let details : PastDetailView = self.storyboard?.instantiateViewController(withIdentifier: "PastDetailView") as! PastDetailView
navigationController?.pushViewController(details, animated: true)
}
}

You need to set table view's delegate and datasource properties in viewDidLoad.
Update your viewDidLoad to look like this:
override func viewDidLoad() {
super.viewDidLoad()
let nibCell = UINib(nibName: "PastTableView", bundle: nil)
mTable.register(nibCell, forCellReuseIdentifier: "cell")
mTable.delegate = self
mTable.datasource = self
apiCalling()
}
