Swift Firebase: List Firebase Children into UICollectionViewCells - swift

Question

I have recently setup FireBase, but have not yet figured out how to embed the children of the "Posts" section into each individual UICollectionViewCell. Currently, the ViewController has this bit of code, where ipCell is the indexPath of the cell. What is returned is no description at all. I hope you can understand, since this has really been bothering me. The array posts is defined before.
import UIKit
import FirebaseDatabase
import FireBase
var posts = [String]()
var ipCell = Int()
var count = Int()
var description = String()
class HomeController: UICollectionViewController,
UICollectionViewDelegateFlowLayout {
let cellId = "cellId"
var newCellN = Int()
let ref = Database.database().reference().child("Posts")
override func viewDidLoad() {
super.viewDidLoad()
count = newCellN
collectionView?.register(PostCell.self, forCellWithReuseIdentifier:
cellId)
// Do any additional setup after loading the view, typically from a
nib.
}
override func collectionView(_ collectionView: UICollectionView,
numberOfItemsInSection section: Int) -> Int {
return newCellN
}
func collectionView(collectionView: UICollectionView, layout
collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex
section: Int) -> UIEdgeInsets {
return UIEdgeInsets(top: 15.0, left: 0.0, bottom: 0.0, right: 0.0)
}
override func collectionView(_ collectionView: UICollectionView,
cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier:
cellId, for: indexPath)
cell.contentView.layer.borderWidth = 0.5
cell.contentView.layer.cornerRadius = 10
cell.contentView.layer.borderColor = UIColor.lightGray.cgColor
cell.backgroundColor = .white /* #040504 */
ipCell = indexPath.item
return cell
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func collectionView(_ collectionView: UICollectionView, layout
collectionViewLayout: UICollectionViewLayout,sizeForItemAt indexPath:
IndexPath) -> CGSize {
return CGSize(width: view.frame.width-20, height: 250)
}
class PostCell : UICollectionViewCell {
override init (frame: CGRect) {
super.init(frame: frame)
setUp()
}

fatalError("init(coder:) has not been implemented")
}
func setUp() {

let screenW = UIScreen.main.bounds.size.width
TextF.frame = CGRect(x: 85, y: 5, width: screenW-110, height:
