CallKit Call hasConnected always returning true - ios

Question

I am working on a VOIP app and implementing CallKit on iOS.
From this link: https://developer.apple.com/documentation/callkit/cxcall/1649013-hasconnected?language=objc
A call is considered connected when both caller and callee can start
communicating.
What does this mean here? Does it mean that a WebRTC or some other audio/video stream must be started in order for it to return true? or does it mean that if user presses the accept call button it is considered connected?
I have the following code to check status of the call and it is always returning true or whatever i give in resolve:
CXCallObserver *callObserver = [[CXCallObserver alloc] init];
NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:uuidString];
BOOL _mybool = false;
for(CXCall *call in callObserver.calls){
if([call.UUID isEqual:[[NSUUID alloc] initWithUUIDString:uuidString]] && !call.hasConnected){
_mybool = true;
resolve(#"true");
}
}
if(!_mybool){
reject(false, false, false);
}

Answer 1

In your code, you are checking the call state in the wrong place. This is creating a problem in your execution.
You have to first setup callobserver with call it. which you have done correctly. But one flag is required didDetectOutgoingCall
func setupCallObserverWithCallKit() {
if #available(iOS 10.0, *) {
didDetectOutgoingCall = false
if callObserver == nil {
callObserver = CXCallObserver()
callObserver!.setDelegate(self, queue: nil)
}
}
}
and then inside callObserver write your logic.
#available(iOS 10.0, *)
func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) {
if call.isOutgoing && !didDetectOutgoingCall {
didDetectOutgoingCall = true
// "Call button pressed"
}
if call.hasEnded == true && call.isOutgoing == false || // incoming end
call.hasEnded == true && call.isOutgoing == true { // outgoing end
// Disconnected
}
if call.isOutgoing == true && call.hasConnected == false && call.hasEnded == false {
// "CXCallObserver : Dialing"
//**Write your logic written in for loop here**
}
if call.isOutgoing == false && call.hasConnected == false && call.hasEnded == false {
// "CXCallObserver: Incoming"
}
if call.hasConnected == true && call.hasEnded == false {
// "CXCallObserver: Connected")
}
}
Note: Though this code is in swift language, it is easily understandable and easily convertible to objective-c

//init
if (#available(iOS 10.0, *)) {
self.callObserver = [CXCallObserver new];
[self.callObserver setDelegate:self queue:nil];
}
and implement a delegate method - CXCallObserverDelegate
#pragma mark - CXCallObserverDelegate
- (void)callObserver:(CXCallObserver *)callObserver callChanged:(CXCall *)call {
//what you need))
//call.isOutgoing
//call.hasConnected
//call.hasEnded
//call.onHold
//call.hasEnded
}
