JSONSerialization.jsonObject returning nil? - ios

Question

Note: I am on step 2.3 here, I am working to integrate stripe with firebase.
I have the following guard let, which will fail. It fails because of the json const.
guard let data = data, let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [String : Any], let accountURLString = json["url"] as? String, let accountURL = URL(string: accountURLString) else {
// handle error
print(": jsonfdshkfdbsh :")
return
}
Unfortunately the following declaration within it fails:
let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [String : Any]
What is wrong with the line? How can I make it work?
Update: (What I have tried but has not worked)
let data = data as Data?
print(data, " datavar")//has a value (not nil)
let json = try? JSONSerialization.jsonObject(with: data!, options: []) as? [String : Any]
print(json, " jsonvar") //nil
let accountURLString = json!["url"] as? String
let accountURL = URL(string: accountURLString!)
Update 2:
I've been wondering and investigating whether the problem may be that request variable path may not be valid(?). However, my testing, with a value I know exists in the database, has not yielded (worked) any results.
if let url = URL(string: backendAPIBaseURL)?.appendingPathComponent("stripe_customers/IYNpofaWUFXfobmFRLMLIEZXxqN2") {// usually the string is: "onboard-user"
var request = URLRequest(url: url)
request.httpMethod = "POST"
print(URLSession.shared.dataTask(with: request), "<-- ay un problem?")
print(request, " this was the request value")
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
print("does thsi run??? ", data)
let data: Data = data!// as Data?
print(data, " ttekjfdsjklfhdas")
//...

Answer 1

The problem turned out to be associated with Update 2. The request was the problem.
I ended changing the code to the following, which worked:
func createStripeConnectAccount(uid: String, completion: #escaping(String?, String?) -> Void) { //accountID, Error
let parameters: [String:Any] = [:]
let url = "https://us-central1-name-fhdskj.cloudfunctions.net/createConnectAccount"
AF.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: [:]).responseJSON { response in
switch response.result {
case .success(let dict):
print(dict)
let successDict: [String: Any?] = dict as! [String: Any?]
let body = successDict["body"] as! [String: Any?]
let acctNum = body["success"] as! String
print(acctNum, "<-- link did it twerk?")
completion(acctNum, nil)
case .failure(let error):
print(error.localizedDescription)
completion(nil, error.localizedDescription)
}
}
}
func createAccountLink(accountID: String, completion: #escaping(String?, String?) -> Void) { //url, Error
let parameters: [String:Any] = ["accountID": accountID]
let url = "https://us-central1-name-fdsad.cloudfunctions.net/createStripeAccountLink"
AF.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: [:]).responseJSON { response in
switch response.result {
case .success(let dict):
print(dict)
let successDict: [String: Any?] = dict as! [String: Any?]
let body = successDict["body"] as! [String: Any?]
let link = body["success"] as! String
print(link, "<-- link did it twerk?")
completion(link, nil)
case .failure(let error):
print(error.localizedDescription)
completion(nil, error.localizedDescription)
}
}
}
You'll have to integrate Alomofire Pod.
