After I received an incoming voip push in the AppDelegate, I reported the incoming call using the method below:
func showIncomingCall(of session: String) {
let callUpdate = CXCallUpdate()
callUpdate.remoteHandle = CXHandle(type: .phoneNumber, value: session)
callUpdate.localizedCallerName = getMemberName(phone: session)
if voiceCallBool {
callUpdate.hasVideo = false
}
if videoCallBool {
callUpdate.hasVideo = true
}
callUpdate.supportsDTMF = false
currentCall = pairedUUID(of: session)
provider.reportNewIncomingCall(with: currentCall!, update: callUpdate, completion: { error in
if let error = error {
print("reportNewIncomingCall error: \(error.localizedDescription)")
}
})
}
After I answered the call, the call was connected. And both the callee and caller is able to have a conversation. After the call, the caller ended the call. This was detected at the callee's end and the following endCall method was called:
func endCall() {
let endCallAction = CXEndCallAction.init(call: currentCall!)
let transaction = CXTransaction.init()
transaction.addAction(endCallAction)
controller.request(transaction) { error in
if let error = error {
print("endSession failed: \(error.localizedDescription)")
}
}
}
The CallKit UI failed to dismiss with the error message: "The operation couldn’t be completed. (com.apple.CallKit.error.requesttransaction error 4.)". Why is this so, even though the same uuid (CurrentCall) is used for reporting the incoming call and for ending the same call? Please help. Thanks.

I need to run some code when the app is closed to remove the client from a game. To do this I'm wanting to execute a Google Cloud Function for the server to do the cleanup - the function works, I guess similar to this question I just do not have enough time, and I'm running a completion handler so it's not like iOS thinks the function is finished straight away.
I have seen multiple questions on this, many of which are rather old and do not include answers for the SwiftUI Lifecycle. I have seen this exact issue and a potential answer here, however I'm not using the Realtime Database, I'm using Firestore so there is no equivalents for the onDisconnect methods.
I have seen that you can increase the time you need when the application finishes through beginBackgroundTask(expirationHandler:), I just can't find anywhere to state this can be done through SwiftUI Lifecycle, what I have so far:
.onReceive(NotificationCenter.default.publisher(for: UIApplication.willTerminateNotification), perform: { output in
Backend().removeFromGame(gameCode: otp, playerName: "name", completion: { res, error in
if error != nil{
print(error)
}
})
})
The function called is as follows:
func removeFromGame(gameCode: String, playerName: String, completion: #escaping (Bool?, Error?) -> Void){
Functions.functions().httpsCallable("removeFromGame").call(["gameCode": gameCode, "playerName": playerName]){ result, error in
if let error = error as NSError? {
if error.domain == FunctionsErrorDomain{
_ = FunctionsErrorCode(rawValue: error.code)
let errorDesc = error.localizedDescription
_ = error.userInfo[FunctionsErrorDetailsKey]
print(errorDesc)
}
}else{
print("Removed successfully")
}
}
}
I have seen in this Apple doc how to use the API:
func sendDataToServer( data : NSData ) {
// Perform the task on a background queue.
DispatchQueue.global().async {
// Request the task assertion and save the ID.
self.backgroundTaskID = UIApplication.shared.
beginBackgroundTask (withName: "Finish Network Tasks") {
// End the task if time expires.
UIApplication.shared.endBackgroundTask(self.backgroundTaskID!)
self.backgroundTaskID = UIBackgroundTaskInvalid
}
// Send the data synchronously.
self.sendAppDataToServer( data: data)
// End the task assertion.
UIApplication.shared.endBackgroundTask(self.backgroundTaskID!)
self.backgroundTaskID = UIBackgroundTaskInvalid
}
}
Just cannot seem to implement it correctly within the new way of getting these system notifications?
I'm working in a app that uses Apple Pay, and everything was working, but suddenly this crash start to happen
func startPaymentWith(output: PaymentHandlerResponseProtocol?) {
self.output = output
self.output?.startProcess()
// Create our payment request
let paymentRequest = PKPaymentRequest()
paymentRequest.paymentSummaryItems = paymentSummaryItems
paymentRequest.merchantIdentifier = "abcde.abcdef"
paymentRequest.merchantCapabilities = .capability3DS
paymentRequest.countryCode = "BR"
paymentRequest.currencyCode = "BRL"
paymentRequest.supportedNetworks = self.supportedNetworks
print("comoestaovalorsemreplace \(paymentRequest.paymentSummaryItems[0].amount)")
// Display our payment request
paymentController = PKPaymentAuthorizationController(paymentRequest: paymentRequest) // Here happens the EXC_BAD_ACCESS
paymentController?.delegate = self
paymentController?.present(completion: { (presented: Bool) in
if presented {
debugPrint("Presented payment controller")
} else {
debugPrint("Failed to present payment controller")
self.output?.responseWith(nil)
}
})
}
This is shown in var paymentRequest when mouse pointer is hover above the the variable:
expression produced error: error: /var/folders/sp/8x6rp88s4nv6s3z1635pqdtm0000gq/T/expr139-c248cd..swift:1:65: error: cannot find type 'PassKit' in scope
Swift._DebuggerSupport.stringForPrintObject(Swift.UnsafePointer<PassKit.PKPaymentRequest>(bitPattern: 0x15e4e9da0)!.pointee)
im stuck in how to ending all the last call before report a new incoming call, my function work for 2 call, it mean i can end the first call before report new call
But the problem is after next report, the end call function throw error
Here is my code:
// Handle incoming pushes
func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: #escaping () -> Void) {
// print("Handle incoming pushes: \(payload.dictionaryPayload)")
endCall(thenReportNewCallForUuid: UUID.init())
}
func reportNewCall(uuid : UUID){
let config = CXProviderConfiguration(localizedName: "CallKitExample")
config.includesCallsInRecents = true
config.supportsVideo = true
config.supportedHandleTypes = [.generic]
config.iconTemplateImageData = UIImage(named: "logo_square")!.pngData()
config.maximumCallGroups = 1
config.maximumCallsPerCallGroup = 1
let provider = CXProvider(configuration: config)
provider.setDelegate(self, queue: nil)
let update = CXCallUpdate()
update.supportsHolding = false
update.supportsGrouping = false
update.supportsUngrouping = false
update.remoteHandle = CXHandle(type: .generic, value: uuid.uuidString)
update.hasVideo = true
provider.reportNewIncomingCall(with: uuid, update: update, completion: { error in
print("reportNewIncomingCall \(uuid) error: \(error)")
UserDefaults.standard.set(uuid.uuidString, forKey: "CallUUID")
UserDefaults.standard.synchronize()
})
}
func endCall(thenReportNewCallForUuid : UUID) {
guard let lastCallUUIDString = UserDefaults.standard.string(forKey: "CallUUID"), !lastCallUUIDString.isEmpty else{
return
}
print("end uuid: \(lastCallUUIDString)")
let call = UUID.init(uuidString: lastCallUUIDString)!
let controller = CXCallController()
let endTransaction = CXEndCallAction(call: call)
let transaction = CXTransaction(action: endTransaction)
controller.request(transaction, completion: { error in
if let error = error {
print("endcall Error: \(error)")
self.reportNewCall(uuid: thenReportNewCallForUuid)
} else {
print("endcall Success")
self.reportNewCall(uuid: thenReportNewCallForUuid)
}
})
}
Here is log + error i got

Some one who mark duplicate please show the right answer? Thanks
Does someone facing same problem? Please help
I see at least a couple of issues in your code. But, before that, why are you ending the ongoing call whenever you receive a new incoming call? I'm just curious, because it doesn't seem to be a great user experience.
Anyway, the issues I've found are the following:
At every new incoming call you instantiate a new CXProvider. As stated in the documentation:
A VoIP app should create only one instance of CXProvider and store it for use globally.
You don't invoke the completion handler of the pushRegistry(_:didReceiveIncomingPushWith:type:completion) method. You should invoke it inside the completion handler of the reportNewIncomingCall(with:update:completion:) method.
I think that the errors you're facing are caused by the CXProvider issue. But if you don't fix also the second issue you could incur in another problem: the system will suppose that you haven't reported a new incoming call and so, after a few calls, it will stop to send you new VoIP pushes (this limitation was first introduced in iOS 13).
i've had the same issue and fixed it by moving the instantiation of CXProvider, CXProfiderConfiguration and CXCallController outside of pushRegistry function and inside didFinishLaunchingWithOptions part of AppDelegate, something like this:
private func voipRegistration() {
// Create a push registry object
let mainQueue = DispatchQueue.main
let voipRegistry: PKPushRegistry = PKPushRegistry(queue: mainQueue)
voipRegistry.delegate = self
voipRegistry.desiredPushTypes = [PKPushType.voIP]
config.iconTemplateImageData = #imageLiteral(resourceName: "cometchat_white").pngData()
config.includesCallsInRecents = false
config.ringtoneSound = "ringtone.caf"
config.supportsVideo = false
provider = CXProvider.init(configuration: config)
provider!.setDelegate(self, queue: nil)
}
You have to have a single instance of CXProvider.
The CKContainer.discoverAllIdentities request always fails in my CloudKit app. It has continually failed over the course of several days.
A simplified version of the code that is failing (which results in the same error) is:
private func getContacts(completion: (([CKUserIdentity]?) -> Void)?) {
container.status(forApplicationPermission: .userDiscoverability) { [weak self] status, error in
if let error = error {
print(error)
}
switch status {
case .granted:
self?.discover(completion: completion)
default:
print("status not granted")
}
}
}
private func discover(completion: (([CKUserIdentity]?) -> Void)?) {
let op = CKDiscoverAllUserIdentitiesOperation()
op.qualityOfService = .userInitiated
op.discoverAllUserIdentitiesCompletionBlock = { error in
if let error = error {
print(error)
}
}
op.userIdentityDiscoveredBlock = { identity in
print(identity)
}
op.start()
}
It results in an error being passed to the op.discoverAllUserIdentitiesCompletionBlock. The description of the error in the log is:
<CKError 0x1c4a51a60: "Server Rejected Request" (15/2000); server message = "Internal server error"; uuid = F67453B9-712D-4E5E-9335-929123E3C978; container ID = "iCloud.com.huntermaximillionmonk.topdraw">
Previously, this operation would work, but only for certain iCloud users. Now it's not for both of my test users.
Problem:
This was a problem in iOS 11.0
Based on my testing:
This works ok in Xcode 9.2 / iOS 11.2.1 on the device (not simulator)
After resetting the simulator works for the first time, doesn't work subsequently, however on the device it works repeatedly.
Code:
let queue = OperationQueue()
func requestPermissions(for permissions: CKApplicationPermissions,
completionHandler: #escaping (CKApplicationPermissionStatus, Error?) -> ()) {
CKContainer.default().requestApplicationPermission(permissions) { status, error in
if let error = error {
print("Error for requesting \(permissions) - \(error)")
}
let statusMessage : String
switch status {
case .granted:
statusMessage = "Granted"
case .denied:
statusMessage = "Denied"
case .couldNotComplete:
statusMessage = "Could not complete"
case .initialState:
statusMessage = "Initial state"
}
print("Permission - \(statusMessage)")
completionHandler(status, error)
}
}
private func discoverAllUsers() {
let operation = CKDiscoverAllUserIdentitiesOperation()
operation.userIdentityDiscoveredBlock = { userIdentity in
print("userIdentity = \(userIdentity)")
}
operation.discoverAllUserIdentitiesCompletionBlock = { error in
if let error = error {
print("Discover all users Error: \(error) ")
}
else {
print("Discover all users completed successfully")
}
}
queue.addOperation(operation)
}
Edit:
Apple fixed this issue day after this answer was posted, coincidence?! I don't think so :)
This is not actually the answer to the question, but a fix that helped me to cross over this error. It will require you to change your app UI interaction and add ContactsUI framework to your project, moreover your user will be responsible for selecting a contact with iCloud related email.
Good news is that the method discoverUserIdentity is still works. So, you can use it to get CKUserIdentity from manually selected contact.
func addContact(_ contact:CNContact) {
var lookUpEmails = [CKUserIdentityLookupInfo]()
for email in contact.emailAddresses {
lookUpEmails.append(CKUserIdentityLookupInfo(emailAddress: (email.value as String)))
}
let checkUserOperation = CKDiscoverUserIdentitiesOperation()
checkUserOperation.userIdentityLookupInfos = lookUpEmails
checkUserOperation.userIdentityDiscoveredBlock = { [unowned self] (identity, info) -> Void in
if identity.hasiCloudAccount {
if let recordID = identity.userRecordID {
//do something with discovered user
}
checkUserOperation.cancel()
}
}
checkUserOperation.queuePriority = Operation.QueuePriority.high
CKContainer.default().add(checkUserOperation)
}
It might sound useless, but in my case, it helped me to solve the Server Rejected Request" (15/2000) error, to fix one of the features of my app and continue to use the other feature related code with less efforts than I thought.
I hope someone will find this helpful.
Just another data point on this that might help with the overall picture. I was still seeing this error on 11.2.5 when I used my own iCloud AppleID (with hundreds of contacts) while running a Test App that called discoverAllIdentitiesWithCompletionHandler. I'd get the dreaded
CKError 0x1c0051730: "Server Rejected Request" (15/2000); server message = "Internal server error".
When I switched to run the exact same code on my daughters iOS11.2.5 device (with just a handful of contacts) the code worked fine.
Leads me to believe there is some rate limiting going on when there are a lot of contacts with iOS11.
(P.S. No errors at all running on iOS10)
First our codes
let req = SignUp()
req.loginName = "abc#abc.com"
req.passWord = "xxx"
do{
let resp = try client.put(req) <---Where we had an error
} catch {
//some error handling
//.....
}
And then, when we input the correct information, everything is fine but when the login credential is wrong, we had expected to get an 401 error with a proper error message, we didn't. And when we traced it trying to find the origin of this, we had traced it back to JsonServicClient.swift (generated from ServiceStack swift plugin for Xcode 7.2), line 266.
public func send<T : JsonSerializable>(intoResponse:T, request:NSMutableURLRequest) throws -> T {
var response:NSURLResponse? = nil
var data = NSData()
do {
data = try NSURLConnection.sendSynchronousRequest(request, returningResponse: &response)
var error:NSError? = NSError(domain: NSURLErrorDomain, code: NSURLErrorUnknown, userInfo: nil)
if let dto = self.handleResponse(intoResponse, data: data, response: response!, error: &error) {
//^^^error here, response is null/can't be null
return dto
}
if let e = error {
throw e
}
return T()
} catch var ex as NSError? {
if let e = self.handleResponse(intoResponse, data: data, response: response!, error: &ex) {
return e
}
throw ex!
}
}
So here is the question, how to properly use ServiceStack swift plugin to get 401 error? When the service returns 400, everything is fine. This problem only happens when the servicestack server api returns 401. Which is by design, we supposed to return 401 when a user authentication fails.
This is a bug in Swift's sendSynchronousRequest which sometimes returns a null response which makes it impossible to determine what the server error response was. I've added a fix for this issue in this commit where it will now throw an unknown Error instead of segfaulting but as Swift doesn't return a HTTP Response we can't query it to return any more info about the error, e.g:
do {
try client.post(request)
} catch let responseError as NSError {
//Swift Bug: 401 returns an unitialized response so status is nil
if let status:ResponseStatus = responseError.convertUserInfo() {
}
}
To get the latest version you can either replace to latest JsonServiceClient.swift or delete the JsonServiceClient.swift and Add/Remove a new Service Reference which will download the latest version.
If you can, you can also switch to use the Async API's which doesn't have this issue:
client.postAsync(request)
.error { responseError in
let status:ResponseStatus = responseError.convertUserInfo()!
status.errorCode //= Unauthorized
}
