I'm really confused by API of web service
Some blocks of data has a format like that:
"ja": "犯罪\u8005の子孫た\u3061が暮\u3089\u3059スラム\u8857\u3002\u5883界線の\u5411\u3053\u3046の人\u3005か\u3089は「族民」\u3068\u3055\u3052\u3059まれ\u3001差\u5225\u3092受\u3051\u3066\u3044た\u3002孤\u5150\u3060\u3063た少年・ルドは\u3001育\u3066の親\u3067\u3042るレグト\u3068\u5171にスラム\u8857に住み\u3001常人離れ\u3057た身体能力\u3092武\u5668に生計\u3092立\u3066\u3066\u3044た\u3002\u3060が\u3042る日\u3001身に覚\u3048のな\u3044罪\u3092\u7740せ\u3089れ\u3001スラムの人\u3005\u3067\u3055\u3048\u6050れる「\u5948落」\u3078\u3068落\u3068\u3055れ\u3066\u3057ま\u3046\u2026\u2026\u3002"
I realized that Swift do not work with those format. But I really don't know in what step I should convert this
My parse func:
URLSession
.shared
.dataTask(with: request) { data, response, error in
if let data = data {
do {
if let sanitisedData = String(data: data, encoding: .utf8)!.map({ String($0) }).filter({ $0 != "\\" }).joined(separator: "").replacingOccurrences(of: "U(.*?)", with: "\\\\u$1", options: .regularExpression).data(using: .utf8) {
let decoder = JSONDecoder()
let decodedResponse = try decoder.decode(Welcome.self, from: sanitisedData)
DispatchQueue.main.async {
self.data = decodedResponse
}
}
} catch let jsonError as NSError {
print("JSON Decode Failed: \(jsonError.localizedDescription)")
}
return
}
}
.resume()
Output:
JSON Decode Failed: The data couldn’t be read because it isn’t in the correct format.
I tried to convert this data to string and that's the result:

If your server response is really without the unicode escaped, that is,
"犯罪\u8005の子孫た\u3061 ...", then try escaping the data as shown in this example code,
to get: "犯罪\\u8005の子孫た\\u3061 ..." (note the \\) and decode it like this:
URLSession
.shared
.dataTask(with: request) { data, response, error in
if let data = data {
do {
if let sanitisedData = String(data: data, encoding: .utf8)!
.replacingOccurrences(of: "\\", with: "\\\\") // <-- here
.data(using: .utf8) {
let decoder = JSONDecoder()
let decodedResponse = try decoder.decode(Welcome.self, from: sanitisedData)
DispatchQueue.main.async {
self.data = decodedResponse
}
}
} catch let jsonError as NSError {
print("JSON Decode Failed: \(jsonError.localizedDescription)")
}
return
}
}.resume()
EDIT-1:
you may also need to do this: .replacingOccurrences(of: "\n", with: "\\n")
