I want to get phone call states in my app.
After some search I found CoreTelephony framework. But that is deprecated in iOS 10. SO is there any other altern

You can try this code:

1. Create the instance of call observer

   @property ( nonatomic ) CXCallObserver *callObserver;
   

2. Initiate the instance and set the delegate

   _callObserver = [CXCallObserver new];
           [_callObserver setDelegate:self queue:dispatch_get_main_queue()];
   

3. Add the call observer delegate

   - (void)callObserver:(CXCallObserver *)callObserver callChanged:(CXCall *)call{
   
       if (call == nil || call.hasEnded == YES) {
           NSLog(@"CXCallState : Disconnected");
       }
   
       if (call.isOutgoing == YES && call.hasConnected == NO) {
           NSLog(@"CXCallState : Dialing");
       }
   
       if (call.isOutgoing == NO  && call.hasConnected == NO && call.hasEnded == NO && call != nil) {
           NSLog(@"CXCallState : Incoming");
       }
   
       if (call.hasConnected == YES && call.hasEnded == NO) {
           NSLog(@"CXCallState : Connected");     
       }
   }
   

In Swift 4.2:

var callObserver: CXCallObserver()

callObserver.setDelegate(self, queue: DispatchQueue.main)

func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) {

    if call == nil || call.hasEnded == true {
        print("CXCallState : Disconnected")
    }

    if call.isOutgoing == true && call.hasConnected == false {
        print("CXCallState : Dialing")
    }

    if call.isOutgoing == false && call.hasConnected == false && call.hasEnded == false && call != nil {
        print("CXCallState : Incoming")
    }

    if call.hasConnected == true && call.hasEnded == false {
        print("CXCallState : Connected")
    }
}
