Event in another store after editing?

[adamsmaka]

Hi, I love your calendar manager!
I had no issues until I'm trying to introduce events editing in my app.

When I create an event, everything is ok. Then when I change its recurrenceRules, it lands in another store or something, because later manager can't remove all events throwing error:

"NSInvalidArgumentException", "Attempt to remove an object that does not belong to this store."

                    rule.recurrenceEnd = EKRecurrenceEnd(end: endRepeat)
                }
                self.calendarManager.saveEvent(event: event, completion: { (error) in

                    } else {
                        completion?()
                    }
                })
            }
            
        } else {
            if let error = error {
                fatalError("Error during getting an Event with ID \(eventId) - \(error.localizedDescription)")
            } else {
                fatalError("No event in the store")
            }
        }
    }
}

AMGCalendarManager.shared.removeAllEvents()

[adamsmaka]

Ok, I found that if I call reset() just before removeAllEvents() then it all works properly. Anyway, weird behavior. :)

[AlbertMontserrat]

The error is because you are using two different calendar managers, i think.
Try change:
self.calendarManager.saveEvent
for:
AMGCalendarManager.shared.saveEvent

Tell me if this worked for you.
Thanks!

[adamsmaka]

Thanks for answer Albert. I'm using the same one. It's just a shortcut variable what works well in every other case.
private var calendarManager: AMGCalendarManager { return AMGCalendarManager.shared }

[AlbertMontserrat]

Check the new version I submitted.
Hope that helps...

I added an option to save an event with span parameters, and now the EventStore is never recreated since the first time it's initialized

[adamsmaka]

Nothing changed, same error if I don't reset store manually before removeAll.

I noticed that changing that EKRecurrenceEnd adds additional string to the event.eventIdentifier

Before:
6D271F9B-C985-4867-AF01-AC8D0614CF72:460BA4B3-7C40-4FF1-8E08-6718DED3474E
After:
6D271F9B-C985-4867-AF01-AC8D0614CF72:460BA4B3-7C40-4FF1-8E08-6718DED3474E/RID=512024940

it looks like updating recurrence end date make some troubles...

[adamsmaka]

Ok, the problem occurred only on Tests target, so don't worry. I can reset store there easily. In production code everything is fine.
I just added a comment to your code, in one place you don't use an argument from function to pass it to eventStore.save method. Now when I set span to .futureEvents manually, eventIdentifier is no longer changing! ✅

[AlbertMontserrat]

Great, so my last vesion helped, right?
