Can't find variable webkit on iOS 14.2

Issue

I'm working on web app that based on AngularJS 1.7. The app is working well on Safari with iOS 12, 14.0, 14.1 - but since i've upgraded my iOS to 14.2/14.3 (checked on both of them) - i'm getting the following error :

ReferenceError: Can't find variable: webkit

It's appears when i'm trying to call webkit - like this :

  try {
    webkit.messageHandlers.callback.postMessage(JSON.stringify(userData));
    
  } catch (err) {
    console.log('There was some problem sending message native app to IOS');

  }

I'm not an iOS native developer - but i'm certain that the callback function hasn't changed, as i mentioned before - it's works well on previous iOS versions...any ideas?

Solution

Try calling it from window (using window.webkit)
