UICollectionView first reusable table cell not showing up - swift

Question

I am working on a game right now and my level selection isn't working right.
The first cell in the collection view won't show up and I can't figure out why.
Here is what it looks like:
Picture of collection view with missing cell
And here is my code for the UICollectionViewController:
the reuse IdentifierList is a list of strings that corresponds to the cells in the storyboard version of this. and I have already checked that they are all spelled correctly.
The one missing is the "MyCell" cell.
class UICollectionCollectionViewController: UICollectionViewController {
var reuseIdentifierList = ["MyCell",
"MyCell2",
"MyCell3",
"MyCell4",
"MyCell5",
"MyCell6",
"MyCell7",
"MyCell8",
"MyCell9",
"MyCell10",
"MyCell11",
"MyCell12",
"MyCell13",
"MyCell14",
"MyCell15",
"MyCell16",
"MyCell17",
"MyCell18"
]
override func viewDidLoad() {
super.viewDidLoad()
reuseIdentifier = reuseIdentifierList[0]
self.collectionView!.register(UICollectionViewCell.self, forCellWithReuseIdentifier: reuseIdentifier)
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: UICollectionViewDataSource
override func numberOfSections(in collectionView: UICollectionView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of items
return reuseIdentifierList.count
}
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
var cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifierList[indexPath.item], for: indexPath)
if indexPath.item != indexPath.startIndex {
cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifierList[indexPath.item], for: indexPath)
}else{
cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifierList[0], for: indexPath)
}
print(indexPath.item)
print(reuseIdentifierList[indexPath.item])
// Configure the cell
return cell
}
#IBAction func unwindToViewControllerLevel (sender: UIStoryboardSegue){
}
}
Thanks in advance

There is no point in creating that many cells. Just have an array to serve as your data source. In your case, it looks like you want your cells to have a button with numbers in order.
class UICollectionCollectionViewController: UICollectionViewController {
// let dataSourceArray = [Int](1...20) // [1, 2, 3 ..., 20]
// EDIT -- SegueId
let dataSourceArray = [(name: "1", segueId: "segueId1"), (name: "2", segueId: "segueId2"), (name: "3", segueId: "segueId3")]
let cellId = "customCellId"
override func viewDidLoad() {
super.viewDidLoad()
self.collectionView?.register(CustomCell.self, forCellWithReuseIdentifier: cellId)
}
// MARK: UICollectionViewDataSource
override func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of items
return dataSourceArray.count
}
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
var cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath)
let item = dataSourceArray[indexPath.item]
cell.button.setTitle(item.name, for: .normal)
let segueId = item.segueId
// use segue id to perform different segues
return cell
}
