I solved it with the EKEventViewController and the .allowsCalendarpreview and .allowsediting settings and the didCompleteWith delegate to do some final logic after the user had added the event...

Ok, I "solved" this overnight with some quality sleep. Instead of forcing the user to enter an arbitrary Calendar name, I'm just going to set the custom calendar to the name of the app so they don't have to deal with it. I was also debating on how to handle the app if the user chooses "don't allow" for access to the Calendar request and now I will just prompt them if they try to go in to the section of the app that uses the calendar and I will inform them that they need to go into the settings to enable the Calendar for this application versus some other initial more extreme options of quitting the app or disabling the front end. After further thought and reading, I determined that a better practice is to let the user still use the other parts of the app and prompt them on the section they can't access with a solution to correct this if they changed their mind and wanted to now allow access to the calendar.

so EKEventStore.requestAccess has been deprecated in iOS 17.... https://developer.apple.com/documentation/eventkit/ekeventstore/1507547-requestaccess/

Ok, so I went ahead and just recreated the connectors is the order I want them on the tab bar controller... I'm still not sure why the drag option, which appears to be there not only didn't work but was very sporadic in the UI, sometimes you can click and drag and other times nothing which I find to be quite uncharacteristic for Apple. My guess is that it's probably more me than them though, I'm probably missing something in this process... :)

Hi All, well never mind! the App Store just emailed me saying my in-app purchase was approved and it now works! all good here! also, if anyone has any questions about implementing this, I'd be glad to help. Feel free to reach out!

hi Claude, thank you for the reply. are you using Swift UI? I am not so I'm wondering if this is the difference. It looks like you are doing this in the UI Preview...
