Issue Description

Hi @richardtop I dont like to create tons of topics but my brain is melting and I cant figure it out.
So the reason I am using CalenderKit is basically getting a user calendar data and show it to other related user.

First side everything works great, no dubt. I am capturing 35 days of calendar data and pulling it to firebase with +startdate +endDate +isallDay + color + title with for - in loop.

Second side with same path I am taking that captured user's data with for in loop, append it and keeping it and what happens is when I try to do .map(EKWrapper.init) that variable I am having this issue

public var color: UIColor {
get {
UIColor(cgColor: ekEvent.calendar.cgColor) ==>> error : Thread 1: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value <<== .calender is red and underlined. Please find the code I use below:
}
}

Code I'm using with CalendarKit

<!-- INSERT CODE HERE -->

// THIS GETS THE EVENTS FROM FIREBASE

    var userEventBox: [EventBox] = []

    func getEvents() {
        
        db.collection(XX).document(XX).collection("Calendar").getDocuments { (querySnapshot, err) in
            if let err = err {
                print("Error getting documents: \(err)")
            } else {
                for event in querySnapshot!.documents {
                    if let startDate = event["startDate"] as? Date,
                       let endDate = event["endDate"] as? Date,
                       let isAllDay = event["isAllDay"] as? Bool,
                       let title = event["title"] as? String,
                       let colorSpace = event["colorSpace"],
                       let colorComponents = event["colorComponents"]{
                        let newEventBox = EventBox(startDate: startDate, endDate: endDate, isAllDay: isAllDay, title: title, colorSpace: colorSpace as! CGColorSpace, colorComponents: colorComponents as! [CGFloat])
                        self.userEventBox.append(newEventBox)
                    }
                }
            }
        }
        generateEvents().  // THEN TRIGGERS SECOND FUNC 
    }



    var generatedEvents = [EKEvent(eventStore: EKEventStore())]

    func generateEvents() {
        
        for createEvents in self.userEventBox {
            
            if self.userEventBox.isEmpty { } else {
                
                if let event = EKEvent() as? EKEvent {
                    event.title = createEvents.title
                    event.startDate = createEvents.startDate
                    event.endDate = createEvents.endDate
                    event.isAllDay = createEvents.isAllDay
                    event.calendar.cgColor = (UIColor.init(cgColor: CGColor(red: 1, green: 1, blue: 1, alpha: 1)) as! CGColor)
                    self.generatedEvents = [event] } else {return}
            }
        }
    }
 // AND HERE IS OVERRIDE EVENTS FOR DATE

    override func eventsForDate(_ date: Date) -> [EventDescriptor] {
        getEvents()         // << AND HERE I AM TRIGGERING THE FIRST FUNC WHERE I GET DATA FROM FIREBASE
        
        let calenderKitEvents = generatedEvents.map(EKWrapper.init)
        
        return calenderKitEvents
    }

Result I am trying to achieve

I have edited the code and this is how it looks like `

func getEvents() {
    
    self.db.collection(XX).document(XX).collection("Calendar").addSnapshotListener { [self] (querySnapshot, error) in
        
        self.userEventBox = []
        
        if let e = error {
            print("There was an issue retrieving data from Firestore. \(e)")
        } else {
            
            if let snapshotDocuments = querySnapshot?.documents {
                
                for doc in snapshotDocuments {
                    
                    let data = doc.data()
                    if let title = data["title"] as? String ,
                       let startDate = data["startDate"] as? String ,
                       let endDate = data["endDate"] as? String ,
                       let isAllDay = data["isAllDay"] as? Bool
                    {
                        let newEventBox = EventBox(startDate: startDate, endDate: endDate, isAllDay: isAllDay, title: title)
                        self.userEventBox.append(newEventBox)
                        print(newEventBox)
                        self.generate()
                    }
                }
            }
        }
    }
}


func generate() {
    
    for generation in userEventBox {
        
        let isoStartDate = generation.startDate
        let isoEndDate = generation.endDate
        
        let dateFormatter = ISO8601DateFormatter()
        let startDate = dateFormatter.date(from:isoStartDate)!
        let endDate = dateFormatter.date(from:isoEndDate)!
        
        if let event = EKEvent() as? EKEvent {

        event.title = generation.title
        event.isAllDay = generation.isAllDay
        event.startDate = startDate
        event.endDate = endDate
        event.calendar.cgColor = CGColor(red: 1, green: 1, blue: 1, alpha: 1)
            self.generated = [event]
        }
        
    }
}

var generated = [EKEvent()]
override func eventsForDate(_ date: Date) -> [EventDescriptor] {
    
    self.getEvents()
    
    let calenderKitEvents = generated.map(EKWrapper.init)
    
    return calenderKitEvents
}

}
`

Now I have this error Thread 1: "You must use [EKEvent eventWithEventStore:] to create an event"

I will really lose my mind. Please help @richardtop
