swipe to delete UITabelViewCell - ios

Question

i tried to do swipe to delete on table view cell, but after swiping that cell several times then only it is getting deleted. how to make it work smoothly(in one attempt swipe and delete)? my code is here :
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
var bId = Helper.businessId as String
let param = ["id" : bId] as! [String : AnyObject]
if editingStyle == .delete{
print(Helper.memId)
print("Deleted")
var myDictionary = self.List[indexPath.row] as! NSDictionary
var bId : String!
if myDictionary.allKeys.count>0
{
bId = myDictionary["id"] as! String
}
var bb = bId as String
if editingStyle == .delete{
print(Helper.memId)
print("Deleted")
Alamofire.request("http://api.noattabeta.com/api/v1/user/current/memberships/\(bb)", method: .delete, headers: ["Authorization":Helper.token]).responseString
{response in
print("In Response")
switch response.result {
case .success:
DispatchQueue.main.async {
let myAlert = UIAlertController(title:"Alert", message: "Do You want to delete",preferredStyle:UIAlertControllerStyle.alert)
let okAction = UIAlertAction(title:"Ok",style:UIAlertActionStyle.default,handler:{ (action: UIAlertAction!) in
self.tableView.reloadData()
})
myAlert.addAction(okAction)
let cancelAction = UIAlertAction(title:"Cancel",style:UIAlertActionStyle.default,handler:{ (action: UIAlertAction!) in
self.tableView.reloadData()
})
myAlert.addAction(okAction)
myAlert.addAction(cancelAction)
self.present(myAlert, animated: true, completion: nil)
}
case .failure(let error):
print(error)
}}}

First I wanted to point out that you're presenting the alert in the wrong place. You make a delete call on the API after it success you're asking if he or she want's to confirm. you have to ask it before you call delete
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
var bId = Helper.businessId as String
let param = ["id" : bId] as! [String : AnyObject]
if editingStyle == .delete{
print(Helper.memId)
print("Deleted")
var myDictionary = self.List[indexPath.row] as! NSDictionary
var bId : String!
if myDictionary.allKeys.count>0
{
bId = myDictionary["id"] as! String
}
var bb = bId as String
if editingStyle == .delete{
print(Helper.memId)
print("Deleted")
let myAlert = UIAlertController(title:"Alert", message: "Do You want to delete",preferredStyle:UIAlertControllerStyle.alert)
let okAction = UIAlertAction(title:"Ok",style:UIAlertActionStyle.default,handler:{ (action: UIAlertAction!) in
// here you can call the delete if user accepts
Alamofire.request("http://api.noattabeta.com/api/v1/user/current/memberships/\(bb)", method: .delete, headers: ["Authorization":Helper.token]).responseString
{response in
print("In Response")
switch response.result {
case .success:
DispatchQueue.main.async {
// remove from your local array e.g
self.dataModel.remove(at: indexPath.row)
// Delete the row before you reload the tableView
self.tableView.deleteRows(at: [indexPath], with: .automatic)
// Now reload your tableView
self.tableView.reloadData()
}
case .failure(let error):
print(error)
})
myAlert.addAction(okAction)
let cancelAction = UIAlertAction(title:"Cancel",style:UIAlertActionStyle.default,handler:{ (action: UIAlertAction!) in
self.tableView.reloadData()
})
myAlert.addAction(okAction)
myAlert.addAction(cancelAction)
self.present(myAlert, animated: true, completion: nil)
}
