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

Question

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)
}

Answer 1

You can use print(startDayDates!) or print(startDayDates ?? "default value").
But I recommend usage of startDayList.compactMap() instead of startDayList.map()to ensure your array doesn't contain nil values.
You can also do like this:
startDayList
.compactMap { $0.created }
.forEach { print($0) }

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 })
