How to disable swipe back gesture globally in ionic 4 angular project

I solved it by adding [swipeGesture]="false" to the ion-router-outlet as described here: https://github.com/ionic-team/ionic/issues/16441

At first, I made the mistake of adding it to all ion-router-outlets in my tabs.html file. That didn't work. Instead, you only have to add it to the ion-router-outlet in the app.component.html file. That did the trick for me.

app.component.html

<ion-app>
  <ion-router-outlet [swipeGesture]="false"></ion-router-outlet>
</ion-app>

I'm using ionic version 4.0.0-beta.17.
