Issue with JSON and Swift - \u00c3\u00a9 é instead of é - json

Question

I am trying to display some JSON data on my iOS app but I am having an issue with displaying it correctly using Swift.
When I use the normal JSONSerializer for \u00c3\u00a9 i get é but I want to display é. I don't understand if it is an issue with say using UTF-16 rather than UTF-8 or something else?
Does anyone have any suggestions how I would convert \u00c3\u00a9 straight to é in Swift, from a JSON received from an API.

Answer 1

Not sure which encoding you're using, but this code works for both .utf8 and .utf16:
let jsonString = "{\"foo\": \"áéíóú\"}"
let data = jsonString.data(using: .utf16)!
do {
let object = try JSONSerialization.jsonObject(with: data, options: [])
if let dict = object as? [AnyHashable: Any], let text = dict["foo"] as? String {
print("Extracted text: \(text)")
}
}
catch let e {
// TODO: Handle error
print("Error processing JSON: \(e)")
}

was the same problem. Necessary use this code, it works:
Alamofire.request(url, method: .get, parameters: params)
.responseJSON{ response in
guard let data = response.data else {return}
do {
let jsonResult = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as! NSDictionary
let json = jsonResult["response_goods"] as! [[String:String]]
print(json) } catch let err as NSError {print(err)
}
}
