I’ve the next code
URLSession.shared.dataTask(with: request) { knowledge, response, error in
guard error == nil else {
print("Error: error calling POST")
completion(nil, error, nil)
return
}
guard let knowledge = knowledge else {
print("Error: Didn't obtain knowledge")
return
}
guard let response = response as? HTTPURLResponse, (200 ..< 299) ~= response.statusCode else {
print("Error: HTTP request failed")
return
}
do {
guard let jsonObject = attempt JSONSerialization.jsonObject(with: knowledge) as? [String: Any] else {
return
}
completion(nil, nil, jsonObject)
} catch {
print("Error: Making an attempt to transform JSON knowledge to string")
return
}
}.resume()
What if the API returns an array of objects? What if “knowledge” is an array? Will let jsonObject = attempt JSONSerialization.jsonObject(with: knowledge) as? [String: Any]
be an array?
How do I alter the code to assist the API returning an json array and a json object?
