Adding a UITableView to a UICollectionViewCell

I'm trying to embed a UITableView into a UICollectionViewCell. I'm managing to get everything to load. However, when it does load it up it seems to randomly use the last loaded value for the UITableView List Items. My DebugPrint Output seems to load all of the CollectionViewCells before even referencing the TableView. Once the CollectionViewCells are set, then it populates the TableView with whatever value it is left with. How can I resolve this so that I'm using the correct values? I suspect it is something to how I'm using IndexPath however I'm fairly new to Swift.
Populating UICollectionView
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: releaseIdentifier, for: indexPath) as! ReleaseCollectionViewCell
let vid: VideoItem
vid = Video[indexPath.item]
let rating = vid.Rating
let denominator = 2.0
let roundedRating = round(rating*denominator )/denominator
if vid.SiteVideoID != 0 {
cell.ReleaseImage.setImageFromURl(stringImageUrl: "(file.BaseURL)/sitePictures/(GetFilePath(ID: String(vid.SiteVideoID)))/(String(vid.SiteVideoID)).jpg")
} else {
cell.ReleaseImage.setImageFromURl(stringImageUrl: "(file.BaseURL)/pictures/(GetFilePath(ID: String(vid.VideoID)))/(String(vid.VideoID))_001.png")
}
cell.ReleaseDate.text = vid.ReleaseDate
cell.ReleaseTitle.text = vid.Title
cell.SiteLogo.setImageFromURl(stringImageUrl: "(file.BaseURL)/siteLogos/" + String(vid.SiteID) + ".png")
if vid.VideoID == 0 {
cell.ReleaseImage.alpha = 0.5
} else {
cell.ReleaseImage.alpha = 1.0
}
indexPathItem = -1
indexPathItem = indexPath.item
debugPrint(indexPathItem)
cell.TagsView.delegate = self
cell.TagsView.dataSource = self
return cell
}
and for populating the TableView
extension MiscCollectionViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if indexPathItem != -1 {
return Video[indexPathItem].Tags.count
} else {
return 0
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let tags = tableView.dequeueReusableCell(withIdentifier: "Tag", for: indexPath) as! TagTableViewCell
debugPrint(String(indexPathItem) + " " + Video[indexPathItem].Tags[indexPath.row])
tags.TagLabel.text = String(indexPathItem) //Video[indexPathItem].Tags[indexPath.row]
return tags
}
}
