I'm creating a PKPass from my firebase server and trying to send it to my IOS application so the user can add it to their wallet but I'm unsure about how to convert the JSON response data that I receive in my IOS app to the necessary PKPass Object.
JSON Response:
{"Content-Length":"1093412","function-execution-id":"xx84qotfonme","Date":"Wed, 29 Apr 2020 00:44:00 GMT","Content-Disposition":"attachment; filename=Event.pkpass","Server":"Google Frontend","alt-svc":"h3-Q050=\":443\"; ma=2592000,h3-Q049=\":443\"; ma=2592000,h3-Q048=\":443\"; ma=2592000,h3-Q046=\":443\"; ma=2592000,h3-Q043=\":443\"; ma=2592000,h3-T050=\":443\"; ma=2592000,quic=\":443\"; ma=2592000; v=\"46,43\"","Etag":"W\/\"10af24-tF23uU9DIoMPnvm2jrbrN4e5JAg\"","x-cloud-trace-context":"104b4a56a5b82510599fa9ab75fcaf0b;o=1","x-powered-by":"Express","Content-Type":"application\/vnd.apple.pkpass; charset=utf-8"}
It seems like the response contains the ticket as it has filename etc.
IOS Side:
var requestData : [String : String]? = [String : String]()
requestData?.updateValue(postId, forKey: "postId");
AF.request(URLString, method: .post, parameters: requestData).responseString { response in
guard let resp = response.data else { return }
do {
let pass = try PKPass(data: resp)
print(pass)
} catch {
print(error)
}
I get this error when I try to pass the response data in the PKPass object
Error Domain=PKPassKitErrorDomain Code=1 "The pass cannot be read because it isn’t valid." UserInfo={NSLocalizedDescription=The pass cannot be read because it isn’t valid., NSUnderlyingError=0x600003c91a70 {Error Domain=PKPassKitErrorDomain Code=1 "(null)"}}
The event.pass is the one apple provides and I have added my passTypeIdentifier & teamIdentifier which seem to be working fine.
You can't just simply change the pass.json in the example. The manifest has to be regenerated and resigned.
You pass is failing to load because you are using the original signature from the example, but you have changed the data in pass.json which renders the signature invalid.

I had some working code that was getting results from a MySQL DB on a remote web server. It is no longer working and I keep getting the message responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength). Here is some code...
Alamofire.request(ADS_URL, method: .get).validate().responseJSON { response in
print("Request: \(String(describing: response.request))") // original url request
print("Response: \(String(describing: response.response))") // http url response
print("Result: \(response.result)") // response serialization result
switch response.result {
case .success(let value):
let json = JSON(value)
print ("JSON: \(json)")
if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
print("Data: \(utf8Text)") // original server data as UTF8 string
}
case .failure(let error):
print("Error while querying database: \(String(describing: error))")
return
}
}
I am also using SwiftyJSON. Here are the results of the code...

Error: responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength)
I have tried using .response and .responseString, but I get no information returned. I am completley stumped. This was all working fine. Hopefully there is someone that can shed some light on this?
Just simply change .responseJSON to .responseData.
And after this parse data:
let jsonDecoder = JSONDecoder()
let parsedData = try jsonDecoder.decode(T.self, from: data)
and no error:
(Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength)
What worked for me was changing the encoding from JSONEncoding.default to URLEncoding.default!
Updating from Alamofire 4 to 5 caused the issue in my case.
By default, it seems that Alamofire 5 returns the error Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength for empty response body with status code 200. So adding 200 to the list of emptyResponseCodes resolved the issue for me:
request.responseData(emptyResponseCodes: [200, 204, 205]) { ... } // the default is [204, 205]
What worked for me was changing from .responseData to .response
Commonly this error comes when your API is 'GET' type and you pass 'POST' type.
The same problem I faced and my solution is I replace .post to .get and then this error removed.
For AFNetworking 3.0 :-
go given path,
pods > Pods > AFNetworking > Serialization > AFURLResponseSerialization.m
then replace line no 228 (self.acceptableContentTypes = [NSSet setWithObjects:#"application/json", #"text/json", #"text/javascript", nil];)
with
self.acceptableContentTypes = [NSSet setWithObjects:#"application/json", #"text/json", #"text/javascript", #"text/html", nil];
Because of your response in form of text/html but that is not mentioned in AFNetworking then we add it manually.
Note:- I debugging this problem for Alamofire.
When server sends back no response, Alamofire shows this message in the .failure block if you are printing the error message. Technically it is not an error. Alamofire didn't show this message in its earlier versions, but since one of the recent updates it started showing it.
As I said it is not really an error, but to me its a bug in Alamorfire. And it is very annoying and misleading to keep seeing this in your log when there is no error on your client or server side.
Here is how I silent it:
if (response.data?.count)! > 0 {print(error)}
And I do it when there is no response from the server, which is the expected behaviour since server is not supposed to send response in some cases.
Alamofire.request(MY_URL, method: .get, parameters: ["blabla": blablabla])
.validate(statusCode: 200..<300)
.responseJSON {
response in
switch response.result {
case .success(let value):
self.processResponse(value)
case .failure(let error):
if (response.data?.count)! > 0 {print(error)}
}
}
So the error message doesn't shows when nothing is returned from the server. In my opinion this should be the default behaviour.
Though the question is quite old, I wanted to provide to others what I recently discovered.
Since the error message is very generic and it doesn't help much, check that the url format you are using is correct. I've gotten this only to discover that the url format was incorrect. Once fixed things started working fine.
I'm working on a subscription IAP. I set all purchases up, their details come back well, I can do the purchases in sandbox and get all the messages alright. The problem I have now is checking the receipt. I always get a URL returned alright, but when I try to read it I keep getting error that the file does not exist. So I try and refresh with SKReceiptRefreshRequest. Try again, still same.
I have uninstalled app on simulator and two real devices, try again from new install and same problem. One thing I realised, one of the real devices displays the password prompt request with [Sandbox] mention. However after two prompts (including accepting password), instead of purchase completed I get a "user/password don't match" message. On simulator when prompted for itunes account and password it all goes through but the actual purchase confirmation never comes (I waited 4 minutes, stable internet connection).
This is the validation process (I have changed it quite a few times, from different tutorials and other people's problems)
let receiptURL = Bundle.main.appStoreReceiptURL
func receiptValidation() {
print("1")
print("2", receiptURL)
do {
print("3")
let receiptData = try Data(contentsOf: receiptURL!, options: .alwaysMapped)
print(receiptData)
let receiptString = receiptData.base64EncodedString(options: [])
let dict = ["receipt-data" : receiptString, "password" : "\(password)"] as [String : Any]
do {
print("4")
let jsonData = try JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted)
if let sandboxURL = Foundation.URL(string:"https://sandbox.itunes.apple.com/verifyReceipt") {
print("5")
var request = URLRequest(url: sandboxURL)
request.httpMethod = "POST"
request.httpBody = jsonData
let session = URLSession(configuration: URLSessionConfiguration.default)
let task = session.dataTask(with: request) { data, response, error in
print("6")
if let receivedData = data,
let httpResponse = response as? HTTPURLResponse,
error == nil,
httpResponse.statusCode == 200 {
print("7")
do {
print("8")
if let jsonResponse = try JSONSerialization.jsonObject(with: receivedData, options: JSONSerialization.ReadingOptions.mutableContainers) as? Dictionary<String, AnyObject> {
print(jsonResponse, jsonResponse.count)
// parse and verify the required informatin in the jsonResponse
} else { print("Failed to cast serialized JSON to Dictionary<String, AnyObject>") }
}
catch { print("Couldn't serialize JSON with error: " + error.localizedDescription) }
}
}
print("51")
task.resume()
} else { print("Couldn't convert string into URL. Check for special characters.") }
}
catch { print("Couldn't create JSON with error: " + error.localizedDescription) }
}
catch {
let appReceiptRefreshRequest = SKReceiptRefreshRequest(receiptProperties: nil)
appReceiptRefreshRequest.delegate = self
appReceiptRefreshRequest.start()
print("Couldn't read receipt data with error: " + error.localizedDescription) }
}
func requestDidFinish(_ request: SKRequest) {
print("???")
do {
let receipt = try Data(contentsOf: receiptURL!) //force unwrap is safe here, control can't land here if receiptURL is nil
print(receipt)
} catch {
print("WTF NO RECEIPT")
// still no receipt, possible but unlikely to occur since this is the "success" delegate method
}
}
And this is the Debugging output from running the app. receiptURL varies between simulator/real device, but other then that everything remains the same.

Why can't I get the receipt created, or found? Is it a device problem, a bug or am I oblivious to something?
The whole IAP process works asynchronously due to which you will not receive the receipt data unless the whole process has been completed successfully. I can't see the whole code based on what you have pasted in your question above but if you are trying to access the receipt data immediately on the action of a button or something similar, you will not get it.
The correct way to access receipt data is to try accessing the receipt based on success completion handler callback of your IAP request. Once you submit the IAP request there is a server side process which takes care of processing the IAP and then a callback handler from IAP SKPaymentTransactionObserver class is triggered. Using the notification handler from this class you can send the update to your ViewController to check for receipt data.
While further researching, I have found the following article, which solved the problem

Important: If you mistakenly use a sandbox tester account to log in to a production environment on your test device instead of your test environment, the sandbox account becomes invalid and can’t be used again. If this happens, create a new sandbox tester account with a new email address.
This code previously works, and suddenly after several works around it stopped and return an Error 401.
Alamofire.request(WebServices.URLS().TabDataURL, method: .post, parameters: reqParams).validate().responseJSON { response in
let statusCode = (response.response?.statusCode) //Get HTTP status code
guard response.result.isSuccess, let value = response.result.value else {
// FIXME:you need to handle errors.
print("Status, Fetching News List:", statusCode)
return
}
I have check via Postman, the parameters are correct. Infact, I can also login (by passing 2 parameters). But when I want to pull in a JSON data from server, I am getting 401.
my main project doesn't have an error. but instead of returning the JSON data, it gave me an Error 401. my other projects (same code format, same server & parameters) is giving me this error.
Error Domain=NSCocoaErrorDomain Code=3840 "JSON text did not start with array or object and option to allow fragments not set." UserInfo={NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.} it worked!
Also, I have check with my other projects -- it seemed I cannot connect aswell. So I suspect it could be because of Alamofire, or my Xcode?
Anyone can help me?
Hi i think your server Response is not correct because, as error indicate object should not start with array same issue i come across tell backend developer to send response in dictionary,
{NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}
let headers = [String: String]()// To add header if any
Alamofire.request(path,method: mType, parameters: parameters, encoding: JSONEncoding.default, headers : headers) .responseJSON
{ response in
//----- this code always works for me. & You don't need add header if not required.
if let JSON = response.result.value {
print("JSON: \(JSON)")
if response.response?.statusCode == 200
{
successCompletionHandler(JSON as! NSDictionary)
}
else if response.response?.statusCode == 401
{
failureCompletionHandler(JSON as! NSDictionary)
}
else
{
failureCompletionHandler(JSON as! NSDictionary)
}
}
else
{
print("error message")
failureCompletionHandler([WSAPIConst.ERROR:WSAPIConst.ERROR_MESSAGE])

}
I am using Alamofire for calling my API .
below is is the code.
func alamofirePost() {
let headers: HTTPHeaders = [ "content-type": "x-www-form-urlencoded"]
let todosEndpoint: String = "http://54.244.108.186:4000/api/post_upc"
let newTodo: [String: Any] = ["UPC": codeTextView.text, "DATE_TIME": currentTime() ]
print("i am in alamo")
Alamofire.request(todosEndpoint, method: .post, parameters: newTodo ,encoding: JSONEncoding.default,headers: headers )
.responseJSON { response in
guard response.result.error == nil else {
// got an error in getting the data, need to handle it
print("error calling POST on /todos/1")
print(response)
print(response.result.error!)
return
}
when i call the function , it is trying to inserting null values in the database
INSERT INTO `UPC`(`UPC`,`DATE_TIME`) VALUES (NULL,NULL)
Below is the response when i do in postman app.
can someone please help
Firstly in your Postman request you are POSTing your body as x-www-form-urlencoded but in your Swift example you are specifying that header as well. BUT you're actually submitting your POST body as a JSON payload. In contrast, your Postman request is a set of key/value pairs.
Additionally, the two keys appear to be named differently from your Swift example and your Postman example.
Swift uses UPC and DATE_TIME while Postman has upc_app and dttm_app so at a minimum you'll want to ensure you send along what your API expects
The server that I am using returns error messages in the HTTP status message. For example, it will return "400 User already exists" rather than "400 Bad Request".
I would like to access the string "User already exists" in the response method called by Alamofire. However, I cannot find any way to access this string.
I found this question on StackOverflow already: Swift Alamofire: How to get the HTTP response status code
Unfortunately, no one gives an answer to the question. :(
Here is where Chrome shows where the error is:
I would suggest trying to print out all the possible data fields that you are given and see what you can find. Please try the following example and see if that sheds any light.
let URL = NSURL(string: "your/url/to/somewhere")!
let parameters = ["foo": "bar"]
Alamofire.request(.POST, URL, parameters: parameters)
.response { request, response, data, error in
println("Request: \(request)")
println("Response: \(response)")
println("Error: \(error)")
if let data = data as? NSData {
println("Data: \(NSString(data: data, encoding: NSUTF8StringEncoding)!)")
}
}
Return response in json format from the server and then i think you'll be able to get the appropriate status.
I've implemented that thing using php codeigniter..from where my response is like
$response['status'] = 'user_already_exists';
$this->response($response, 400);
Now in swift you can go with this
Alamofire.request(.POST,URL, parameters:parameters) .responseJSON
{
(request, response, data, error) in
var json = JSON(data!) //I've used swiftyJSON for reading json response
let status = json["status"].stringValue
println("Status : \(status)")
}
Hope this may help you.
