I'm also having the issue which is well described here: https://stackoverflow.com/questions/58781640/ekeventeditviewcontroller-is-presented-with-a-disabled-add-button
This behaviour has changed in iOS 13 - previously the "Add" button was enabled when the EKEventEditViewController was presented.
Can anyone help?
I am also having this same issue.
Pre iOS 13 the `Add` button was enabled when the controller was presented. Post iOS 13 certain values within the event need to be changed before the `Add` button is enabled.
