Getting crash when ice candidate delegate method called - ios

Please help what is the issue.???
webrtc library calling some internal method and getting excess_bad. and crashed
If needed any more information plz ask.
//code
let iceServer = RTCICEServer(uri:URL(string: resturi), username: “***”, password: “***”)
// Enable SSL globally for WebRTC in our app
let pcFactory:RTCPeerConnectionFactory = RTCPeerConnectionFactory()
let rtcConfiguration = RTCConfiguration()
rtcConfiguration.iceServers = [iceServer!]
let pair1 = RTCPair(key: "OfferToReceiveAudio", value: "true")
let pair2 = RTCPair(key: "OfferToReceiveVideo", value: "false")
let pair3 = RTCPair(key: "DtlsSrtpKeyAgreement", value: "true")
self.mediaConstraints = RTCMediaConstraints(mandatoryConstraints: [pair1!,pair2!], optionalConstraints:[pair3!])
// Create the peer connection using the ICE server list and the current class as the delegate
let localStream:RTCMediaStream = pcFactory.mediaStream(withLabel: “12345”)
let audioTrack:RTCAudioTrack = pcFactory.audioTrack(withID: “123456”)
audioTrack.delegate = self
let status = localStream.addAudioTrack(audioTrack)
self.peerConnection = pcFactory.peerConnection(with: rtcConfiguration, constraints: self.mediaConstraints!, delegate: self)
let pstatus = self.peerConnection!.add(localStream)
print(status)
print(pstatus)
//Let’s look at how the offer is created, which initiates the call.
self.peerConnection!.createOffer(with: self, constraints: self.mediaConstraints)
I am getting sip here.
public func peerConnection(_ peerConnection: RTCPeerConnection!, didCreateSessionDescription sdp: RTCSessionDescription!, error: Error!)
getting crash when this delegate called.
func peerConnection(_ peerConnection: RTCPeerConnection!, gotICECandidate candidate: RTCICECandidate!)

Please check your iceServer is Running fine or not, I have used Following iceServers and resolved the crash. Or you can build your own STUN server. It may be one of reason you are getting the crash.
let iceServer1:RTCICEServer = RTCICEServer.init(uri: URL.init(string: "stun:stun.l.google.com:19302"), username: "", password: "")
OR
let iceServer2:RTCICEServer = RTCICEServer.init(uri: URL.init(string: "turn:numb.viagenie.ca"), username: "webrtc#live.com", password: "muazkh")

Crash log in Xcode

Apologies for my ignorance, I've tried searching around but couldn't find an answer.
I've recently tried uploading my app onto the app store but Apple came back saying the app crashes on launch and attached the crash log.
I've tried symbolicating the crash log by dragging the log into Xcode -> Windows -> Devices -> View Device Logs
Part of the snippet is returned as follows:

App crashes when loading UIWebView in new devices

I am some days with a problem I can't understand.
My hybrid app communicates with a webservice that returns an encrypted text with the html to render. Then the app decrypt this text and render the WebView with the html. This html use a css file that is embedded in app.
What happend is when I debug by XCode nothing happen, but when I download the same version from App Store, the app crashes when the WebView will load. This happen only in new devices, like iPhone 6 and iPad Mini 3. In oldest devices works fine.
I'm debugging in Simulator and iPhone 6 and any problems occurs.
I tried don't use the css local file but the problem continues.
Another WebView that don't use crypted html works fine.
Do you have any idea what can be?
Should I developer a native way?

iOS 8 crash log (AVPlayer)

I am unable to diagnose this crash log, which occurs when using the AVPlayer class-- sometimes it happens right away, and sometimes it happens when trying to play the 2nd or 3rd video..

Crash logs like this can be unhelpful. The most likely culprit is a nil pointer somewhere in your code. You may have no option but to step through your code with a debugger making sure that all your variables have the values you expect them to have.
