The browser that supports pointer event, The Hammer doesn't work.

Chrome has began supporting PointerEvent since version 55. If you don’t set inputType on Hammer.manager, Hammer use Pointer Event as a InputType.

But, Hammer.js has bug about Pointer Event. The Hammer doesn’t work anything.

Here is an easy-peasy solution (no need to modify the library code):

const hammer = new Hammer(
  document.getElementById('gesture-element'),
  { inputClass: Hammer.TouchMouseInput } // Does the trick
);
hammer.on('swipe', event => {
  console.log('Swipe works');
});

I tested in with Hammer 2.0.8 on Chrome (Mac), Safari (Mac and iOS 13) and iOS 13 webview.

You can add the following code to the end of the assign(hammer, { … section in v2.0.8 (at the end):

    ,supportPointerEvents(arg) { 
        return SUPPORT_POINTER_EVENTS = arg !== false && prefixed(window, 'PointerEvent') !== undefined; 
    }

Then, call Hammer.supportPointerEvents(false); on app startup (before adding instantiating items). This will effectively turn the pointer-events processing off; and make many of these problem go away (for now anyway).
