Swipe gesture capture two pointers( or fingers)


I’ve tried to capture two pointers on swipe event in ion-slide, but when I log the parameter $event the pointers always are the one. Sometimes the event trigger two times when a swipe my two fingers above the screen.

swipeEvent(e) {

    if(e.changedPointers.length == 2){
        //do some stuff...

<ion-slide *ngFor="let items of apresentacao;let i = index;" (tap)="doubleTapEvent($event)" (swipe)="swipeEvent($event)">


Someone can help me please?
