I want to know how you guys handle errors when using a URLRequest in your app. How do you go about notifying your users that an error has occurred? Do you even notify your users at all? Do you try and reload the URLRequest again? Do you tell your users to close the current screen and open it again with an alert box? I have no clue.
Once there's an error, your app stops. So what do you do when this happens and you have a network issue, bad Json data?
What do you do when you get a "Bad Network Connection (The server is down)" or the URLSession comes back with an error and the internet connection is fine?
Please look at the code below and help me figure out what needs to be done when an error occurs.
let url = URL(string:"http://example/jsonFile.php")
var request = URLRequest(url:url!)
request.httpMethod = "POST"
let postingString = "id=\(id)"
request.httpBody = postingString.data(using: String.Encoding.utf8)
let task = URLSession.shared.dataTask(with: request as URLRequest){(data, response, error) -> Void in
if error != nil {
print("error \(error)")
// *****
// What do you do here? Do you tell your users anything?
// *****
return
}
// Check for Error
if let urlContent = data {
do{
let jsonResult = try JSONSerialization.jsonObject(with: urlContent, options: .allowFragments) as! [String: AnyObject]
print("jsonResult \(jsonResult)")
}
catch{
print("JSON serialization failed")
// *****
// What do you do here? Do you tell your users anything?
// *****
}
}
}
task.resume()
