                    println("YES" )
                    // Uncomment if you want to delete
                    //eventStore.removeEvent(i, span: EKSpanThisEvent, error: nil)
                }
            }
        }
        
        
    }

What about time zones? Does this take that into consideration?

how can i disable the edit
