Ionic2-Calendar | A calendar component based on Ionic framework | iOS library

I am developing an Ionic 4 based app with Angular 8 and have a strange situation that has developed. I am using this calendar.

It seems to be similar to this issue... and you will see I have commented there asking how they solved it to no avail.

It works fine on the browser using ionic -serve and WAS working fine on my android device (I haven't gotten to iOS yet). There was an andoid update to my phone last week and since then, the calendar page doesnt work any longer. I have stripped out most of the code and simplified it to the extent that it (almost) works now but I have to remove the datasource object. This leads me to believe there is something wrong with the data in the datasource which I had found before when incorrectly formatted. However, I am uncertain if this is the issue. The startTime and endTimes come from the server and are converted from ISO strings like this:

I am trying to deploy my ionic app to appstore. But I cant able to build this app to --prod. There is no error while deploying for test build. Please help me to fix this.

I was working with ionic 3 framework. I created a calendar app. This is my first app so I have no idea to fix this. I am getting error while running the following command

ionic cordova build ios --prod.

Here is my app module

I am working on PWA with Ionic v4 and Angular PWA service workers. On app.component.ts have a injected service to check if updates are available on PWA and then download and reload.

When I open PWA with the browser the service works fine and If I deploy an update the service worker update the cached PWA and ‘auto-reload’ the page.

The problem comes with PWA/standalone mode, on iOS when the PWA is added to homescreen it not refreshes anymore even killing it with the task app list. Only If I shutdown the device and on again it refreshes the state of the app. On Android devices all works as expected on PWA mode.

This is my version checker service implemented with Angular service worker:

So there's this repo of the original npm package: https://github.com/twinssbc/Ionic2-Calendar.

And its fork, which does not exist as a npm package, that I want to use in my project: https://github.com/twinssbc/Ionic2-Calendar/tree/24feacfb29102ec61d6814281867e356fb1a9ee0.

I want to be able to use this fork in my Ionic3 project as I use the original package. How do I achieve this? Should I create my own npm package with the fork or is there some simpler way?

I've been searching for a few days now for this issue. There's probably something quite obvious I'm missing out here but this stupid issue is making me quite agressive ;)

So here is my problem:

For a cross-platform app I'm making I use ionic with Angular 5. I want to have a calendar filled with meetings retrieved from an API. The json returned from the API has an array of meetings. Something like this:
