How do I remove "Optional()" from object in an array

So im using CloudKit and fetching all the data into an array as [StartDay], my StartDay class looks like this:

import UIKit
import CloudKit

class StartDay {

var recordID: CKRecord.ID!
var wakeUp: String!
var sleptWell: String!
var dNN: String!
var created: String! {

    get { 
        return created
    }
}
}`

My function loads get an arraylist, which contains information received from the database. In my database it stands like this: "22.01.09:

    func checkIfButtonShouldBeEnabled(startDayList: [StartDay]){

    let startDayDates = startDayList.map{$0.created}

    for i in 0..<startDayDates.count {

        print(startDayDates)

    }

}`

OUTPUT: Optional("22.01.2019") Optional("22.01.2019")

I want to remove "Optional()", so it only says "22.01.2019", how can I do so?

UPDATE: FETCH FUNC

func loadStartDay() -> [StartDay]{

    let predicate = NSPredicate(value: true)
    let query = CKQuery(recordType: "StartDay", predicate: predicate)
    let operation = CKQueryOperation(query: query)

    var startDays: [StartDay] = []
    operation.desiredKeys = ["wakeUp", "wellSlept", "dNN", "recordID", "createdDato"]

    operation.recordFetchedBlock = { (record:CKRecord) in
        let newStartDay = StartDay()

        newStartDay.wakeUp = record.object(forKey: "wakeUP") as? String
        newStartDay.sleptWell = record.object(forKey: "sleptWell") as? String
        newStartDay.dNN = record.object(forKey: "dNN") as? String
        newStartDay.recordID = record.object(forKey: "recordID") as? CKRecord.ID
        newStartDay.created = record.object(forKey: "createdDato") as? String

        print(newStartDay.created)

        startDays.append(newStartDay)

    }

Solution

As you designed the database model you exactly know which record attributes always exist. Declaring class properties as implicit unwrapped optional as an alibi not to write an initializer is very bad practice.

Assuming every attribute in a record does have a value declare the properties as non-optional and write an initializer.

At least created and recordID are supposed to have always a value!

import UIKit
import CloudKit

class StartDay {

    var recordID: CKRecord.ID
    var wakeUp: String
    var sleptWell: String
    var dNN: String
    var created: String 

    init(record : CKRecord) {
        // recordID can be retrieved directly
        self.recordID = record.recordID
        self.wakeUp = record.object(forKey: "wakeUP") as! String
        self.sleptWell = record.object(forKey: "sleptWell") as! String
        self.dNN = record.object(forKey: "dNN") as! String
        self.created = record.object(forKey: "createdDato") as! String
    }
}

and create instances with

operation.recordFetchedBlock = { record in
    startDays.append(StartDay(record: record))
}

Now the Optional has gone.

print(startDayList.map{ $0.created })
