Fatal error: unexpected found nil while unwrapping an Optional value - arrays

Question

I have a problem with an array of data, in this data array I send the name of 6 images so that later they are loaded in a CollectionView, the 6 images load well, without any problem, but when I add a String value to send it gives me a error that is empty:
This is my class where is my data array:
import UIKit
class HBook{
var imagenB: UIImage!
var estatus: String!
init(estatus: String, imagenB: UIImage) {
self.estatus = estatus
self.imagenB = imagenB
}
class func getData() -> [HBook]{
let rawData = [
["imagenB":"book1"],
["imagenB":"book2"],
["imagenB":"book3"],
["imagenB":"book4"],
["imagenB":"book5"],
["imagenB":"book6"],
["estatus":"No reservado"]
]
var hbook:[HBook] = []
for item in rawData{
hbook.append(HBook(estatus: item["estatus"]!, imagenB: UIImage(named: item["imagenB"]!)!))
}
return hbook
}
}
I print my data array to see which variable is empty, but apparently all have an assigned value:
I do not know why I'm sending an empty value.
This information was retrieved in another class that has a CollectionView and a Label, the method where I passed the information is in the cellForItemAt method:
class DetailViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
#IBOutlet weak var contenedorCollection: UIView!
#IBOutlet weak var myCollection: UICollectionView!
#IBOutlet weak var pages: UIPageControl!
#IBOutlet weak var estatus: UILabel!
var hbook = HBook.getData()
var nombreH = ""
override func viewDidLoad() {
super.viewDidLoad()
pages.numberOfPages = hbook.count
self.title = nombreH
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return hbook.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! CellCollectionViewCell
cell.imageview.image = hbook[indexPath.row].imagenB
estatus.text = hbook[indexPath.row].estatus
return cell
}

I think the problem is in data class. Please replace your HBook class with following code and it will work without any further change :
class HBook{
var imagenB: UIImage?
var estatus: String?
init(estatus: String? = nil, imagenB: UIImage? = nil) {
self.estatus = estatus
self.imagenB = imagenB
}
class func getData() -> [HBook]{
let rawData = [
["imagenB":"book1","estatus":"No reservado"],
["imagenB":"book2","estatus":"No reservado"],
["imagenB":"book3","estatus":"No reservado"],
["imagenB":"book4","estatus":"No reservado"],
["imagenB":"book5","estatus":"No reservado"],
["imagenB":"book6","estatus":"No reservado"]
]
var hbook:[HBook] = []
for item in rawData{
if let image = item["itemnB"]{
hbook.append(HBook(estatus: item["estatus"], imagenB:UIImage(named:image)))
}else{
hbook.append(HBook(estatus: item["estatus"]))
}
}
return hbook
}
}
