[Solved] Setting rootNav shows blank white screen on iOS

Ionic Framework ionic-v3

Solved.

Relates to Problem to call setRoot in my Alert callback

I saw in the docs that Alerts have a .dismiss() function which returns a promise, and if changing the rootNav in an Alert close handler, you must call .dismiss() and then call nav.setRoot() inside the returned promise

skip() {
    let confirm = Alert.create({
      title: 'Skip',
      message: 'Are you sure you want to skip changing your PIN?',
      buttons: [
        { text: 'Cancel', role: 'cancel' },
        { text: 'Skip', handler: () => {
          confirm.dismiss().then(() => {
            this.nav.setRoot(TabsPage);
          })
          }
        }
      ]
    });
    this.nav.present(confirm);
  }
