Sinch video doen't want to work on iOS (Swift) - ios

Question

So basically I want to enable Sinch Video in iOS application.
For testing purposes I've created SinchManaevger which is singleton and I instatiate it in AppDelegate:
class SinchManager: NSObject, SINClientDelegate, SINCallClientDelegate {
static let sharedInstance = SinchManager()
var client: SINClient?
func initSinchClientWithUserId(id: String) {
if client == nil {
if case .Authenticated(let currentUser, _) = SessionManager.sharedInstance.state.value {
self.client = Sinch.clientWithApplicationKey("xyz", applicationSecret: "xyz", environmentHost: "sandbox.sinch.com", userId: currentUser.username)
print("sinchClient")
print(client!)
self.client!.delegate = self
self.client!.setSupportCalling(true)
self.client!.enableManagedPushNotifications()
self.client!.start()
self.client!.startListeningOnActiveConnection()
}
}
}
func clientDidStart(client: SINClient!) {
print("clientDidStart")
self.client!.callClient().delegate = self
}
func clientDidStop(client: SINClient!) {
print("clientDidStop")
}
func clientDidFail(client: SINClient!, error: NSError!) {
print("clientDidFail")
}
func client(client: SINCallClient!, didReceiveIncomingCall call: SINCall!) {
print("didReceiveIncomingCall")
let sinchVC = SinchVC(username: currentUser.username)
let sinchNC = DNMMainNC(rootViewController: sinchVC)
sinchVC.call = call
}
}
And I've created Sinch ViewController which is initialized with username which will be called:
class SinchVC: UIViewController, SINCallDelegate {
private let videoController = SinchManager.sharedInstance.client!.videoController()
private let audioController = SinchManager.sharedInstance.client!.audioController()
private let callClient: SINCallClient
private var call: SINCall!
let username: String
private var mainView: SinchView { return view as! SinchView }
override func loadView() {
view = SinchView()
}
init(username: String) {
self.username = username
self.callClient = SinchManager.sharedInstance.client!.callClient()
super.init(nibName: nil, bundle: nil)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func viewDidLoad() {
super.viewDidLoad()
call.delegate = self
self.mainView.videoView.addSubview(self.videoController.localView())
self.videoController.localView().contentMode = .ScaleToFill
if self.call.direction == SINCallDirection.Incoming {
self.audioController.startPlayingSoundFile(self.pathForSound("incoming.wav") as String, loop: true)
}
if self.call.details.videoOffered {
print("video offered")
self.mainView.videoView.addSubview(self.videoController.localView())
self.videoController.localView().contentMode = .ScaleToFill
}
mainView.videoView.addSubview(self.videoController.localView())
mainView.answerButton.addTarget(self, action: #selector(answer), forControlEvents: .TouchUpInside)
mainView.declineButton.addTarget(self, action: #selector(decline), forControlEvents: .TouchUpInside)
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
self.audioController.enableSpeaker()
}
func pathForSound(string: String) -> NSString {
let nsSt = NSBundle.mainBundle().resourcePath! as NSString
return nsSt.stringByAppendingPathComponent(string)
}
func answer() {
call.answer()
}
func decline() {
call.hangup()
}
func callDidEstablish(call: SINCall!) {
print("callDidEstablish")
}
func callDidEnd(call: SINCall!) {
print("callDidEnd")
}
func callDidProgress(call: SINCall!) {
print("callDidProgress")
self.audioController.startPlayingSoundFile(self.pathForSound("ringback.wav") as String, loop: true)
}
func callDidAddVideoTrack(call: SINCall!) {
print("callDidAddVideoTrack")
mainView.videoView.addSubview(self.videoController.remoteView())
}
}
Problem is when I try to call from my app to other phone with my app nothing happens (didReceiveIncomingCall delegate method doesn't get called at all)
If I try to call from my app to SinchVideo sample app then video call gets initiated normal. But when i call from SinchVideo app to my app nothing happens in my app. So probably i've forgot to add some notification or something to tell my app when the call is incoming. If you could help I would be very grateful. Thanks
EDIT: I managed to make didReceiveIncomingCall work but now call.answer isnt working. (nothing happens when call.answer is called and i see that my phone is ringing)

Answer 1

I am not sure what DNMMainNC does in your did recieve incoming call,
let sinchNC = DNMMainNC(rootViewController: sinchVC) What does DNMMainNC do?
sinchVC.call = call // private var?
But its looks kind of weird to set a private var call from your code, should that not be public or have a constructor like your init but with a call
