Loading spinner does not show and breaks app in Beta 11

Have an app that loads a spinner before the page is rendered, however, after the upgrade to Beta 11, the spinner does not load and the app is broken. The call is in the ngAfterViewInit as follows:

ngAfterViewInit() {
this.loading = this.loadingCtrl.create({
content: ‘Loading Orders’

    // Start the loading spinner        

this is the console error that comes

Does anyone know the fix or workaround for this issue? Thanks!
