Unable to create new event using CalendarKit when following online tutorial

Question

Please note that I am attempting to add an appointment on an iPhone 13 Pro Max simulator, where I am not able to create a new event using XCode 13.

I have been basing my code on this sample,

https://github.com/richardtop/CalendarApp

The issue is that I am not able to create new events using CalendarKit. When I follow this tutorial, I get to 13:45 and am unable to create an event. Do I need to add something to my project, like the Calendar.entitlements file? Please note that my app is a little different than what is in the video because I am trying to embed the CalendarKit calendar into a tab that has been designed in Main.storyboard whereas the tutorial indicates that the designer is to be deleted.

So at this point I am only able to create calendar events if I the code directly from https://github.com/richardtop/CalendarApp.git but I have been unable to customize to add it to my own application.

If you wish to view my code you can access it here:

$ git clone https://github.com/john1726/moor3680_prj.git

BTW, the issue here Unable to create new event using CalendarKit has to do with the emulator which has been solved, but this one occurs when I follow the online tutorial on Youtube at https://www.youtube.com/watch?v=iC4XxmExqFA

Answer 1

Ended up using Calendar View because it allows me to work with Main.storyboard UI designer and it also links to Apple's EventKit:
