I am trying to get a UITableView with a UICollectionView to show the following data set correctly inside the UICollectionViews.
the array which contains all this information is

Code Block arregloDeArreglos

here's the data

However, when I scroll horizontally inside the UICollectionViews, the data will get all messed up.

Can you show the whole code of SelectedShowVC?
As I suggested in your previous thread, we need to know how UITableViews and UICollectionViews are managed, including their dataSources.
Especially, we need to know how arregloDeArreglos, modelOfSeason or any other data used for dataSource.

here's the data

Can you show the data as a JSON text? Which makes very, very easier to test your code.

And please show the definition of your table view cell which is currently used.

Here's the data as JSON

ArrayJson

here's the whole VC

ViewController

Especially, we need to know how arregloDeArreglos, modelOfSeason or any other data used for dataSource.

Code Block var modelOfSeason = arraySeasonsEpisodes

its only used as a global variable

and arregloDeArreglos
it's only used in cellForRowAt

its only used as a global variable

Why are you making it global!!! Incredible...

These lines all causes Cannot find in scope error:

Code Block         arrayCast.removeAll()
        arrayCreator.removeAll()
        arrayAiringSeason.removeAll()
        arrayOfSeasonsInt.removeAll()
        arrayCreatorName.removeAll()
        arraySeasonsEpisodes.removeAll()
        arregloDeArreglos.removeAll()
        arraySeasonsEpisodes.removeAll()
        arraySeasonsEpisodes2.removeAll()
        arraySeasonsEpisodes3.removeAll()
        arraySeasonsEpisodes4.removeAll()
        arraySeasonsEpisodes5.removeAll()
        arraySeasonsEpisodes6.removeAll()
        arraySeasonsEpisodes7.removeAll()
        arraySeasonsEpisodes8.removeAll()
        arraySeasonsEpisodes9.removeAll()
        arraySeasonsEpisodes10.removeAll()

All of them are globals?

😅 sorry i have not experienced with this.
i don't have the knowledge to manage information from a UItable to UIcolectionview
so the only way i could solve it is making a global variable to move the previous information and loaded to the UIcollectionview

now i'm trying to investigate how can i send information from the table to collection
i'm trying to make it the same way i treated the information in the UICollectionViewCell
using didSet but still not clue

here's the code so far

Code Block import UIKit
var modelOfSeason = arraySeasonsEpisodes   //this is the global 
class NumberOfSeasonsCell: UITableViewCell, ViewDelegate {
    var modelo: arregloBidimencional? {
        didSet {
            guard let viewModel = modelo else { return }
            let array = viewModel.arregloDeEpisodios
            
            
        }
    }
    
    var compactConstraints: [NSLayoutConstraint] = [NSLayoutConstraint]()
    var regularConstraints: [NSLayoutConstraint] = [NSLayoutConstraint]()
    var largeConstraints: [NSLayoutConstraint] = [NSLayoutConstraint]()
    
    
    lazy var seasonsCollectionView: UICollectionView = {
        let layout = UICollectionViewFlowLayout()
        layout.scrollDirection = .horizontal
        layout.minimumLineSpacing = 30
        let cv = UICollectionView(frame: .zero, collectionViewLayout: layout)
        cv.backgroundColor = UIColor.clear
        cv.register(SeasonCell.self, forCellWithReuseIdentifier: "identifierSeasons")
        cv.showsHorizontalScrollIndicator = false
        cv.translatesAutoresizingMaskIntoConstraints = false
        return cv
    }()
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }
    func contenido(array: arregloBidimencional){
        
    }
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        
        initComponents()
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    func setCollectionViewDataSourceDelegate<D: UICollectionViewDataSource & UICollectionViewDelegate>(_ dataSourceDelegate: D, forRow row: Int) {
        seasonsCollectionView.delegate = dataSourceDelegate
        seasonsCollectionView.dataSource = dataSourceDelegate
        seasonsCollectionView.tag = row
        seasonsCollectionView.setContentOffset(seasonsCollectionView.contentOffset, animated:false) // Stops collection view if it was scrolling.
        seasonsCollectionView.reloadData()
    }
    
    
    var collectionViewOffset: CGFloat {
        set { seasonsCollectionView.contentOffset.x = newValue }
        get { return seasonsCollectionView.contentOffset.x }
    }
    
    
    func initComponents() {
        addComponents()
        setAutolayout()
        activateCurrentLayout()
        
    }
    
    func addComponents() {
        self.addSubview(seasonsCollectionView)
        
    }
    
    func setAutolayout() {
        largeConstraints = [
            seasonsCollectionView.centerYAnchor.constraint(equalTo: self.centerYAnchor),
            seasonsCollectionView.centerXAnchor.constraint(equalTo: self.centerXAnchor),
            seasonsCollectionView.widthAnchor.constraint(equalTo: self.widthAnchor),
            seasonsCollectionView.heightAnchor.constraint(equalTo: self.heightAnchor),
        ]
    }
    
    func activateCurrentLayout() {
        NSLayoutConstraint.activate(largeConstraints)
    }
}
extension UITableViewCell {
    open override func addSubview(_ view: UIView) {
        super.addSubview(view)
        sendSubviewToBack(contentView)
    }
}

yes all of then are global

Well, frankly saying, you may need a lot more emojis which looks more severe.

I often say to developers who say themselves as beginners,

if you need effort to keep two or more arrays consistent, it is an indication of bad design and you should re-organize your code.

You should better avoid using globals just for data passing.

And you are still using non-Capitalized name for structs, that is making your code harder to read.

Anyway, you have multiple UICollectionViews in each UITableView, so each UICollectionView needs to have own its dataSource.
Only one global modelOfSeason would never work appropriately for multiple UICollectionViews.

I will try to find how to fix your code with minimum modification, but it may take long.

By the way, this thread is being too heavy for the Safari of my old MacBook Air.
Maybe too many Code block (<>) is not good for Safari, please try Text attachment next time.

How are all arraySeasonsEpisodesX declared ?
if it is arraySeasonsEpisodesX : SomeType

Why not an array
arraySeasonsEpisodes : [SomeType]

Then no need for the individual tests.

I moved to FireFox. Seems FireFox works well with this site and I can write a reply.

I struggled with your code for hours, and I think the following code would be able to make your collection views work:
(I renamed all the struct names to follow the coding convection of Swift, if you have some specific reason you cannot follow it, please re-interpret them appropriately.)

globals

Code Block var imagenArraaay: [String] = []
var arrayPoster_path: [String] = []
var arrayOverview: [String] = []
var arrayCreatorName: [String] = []
var season_number: String = ""
var season_number2: Int = 0
var air_date: String = ""
var still_path: String = ""
var arrayName: [String] = []
var arrayFirst_air_date: [String] = []
var arrayBackdrop_path: [String] = []
var arrayVote_average: [NSNumber] = []
var arrayid: [NSNumber] = []
var arrayShows: [Tvshows] = []
var arrayCast: [Castt] = []
var arrayCreator: [Created] = []
var arrayAiringSeason: [Episode] = []
//#↓ Remove these many Arrays
//var arraySeasonsEpisodes: [Episodess] = []
//var arraySeasonsEpisodes2: [Episodess] = []
//var arraySeasonsEpisodes3: [Episodess] = []
//var arraySeasonsEpisodes4: [Episodess] = []
//var arraySeasonsEpisodes5: [Episodess] = []
//var arraySeasonsEpisodes6: [Episodess] = []
//var arraySeasonsEpisodes7: [Episodess] = []
//var arraySeasonsEpisodes8: [Episodess] = []
//var arraySeasonsEpisodes9: [Episodess] = []
//var arraySeasonsEpisodes10: [Episodess] = []
//#↓ And use one Array of Array instead
var arrayOfArraySeasonsEpisodes: [[Episodess]] = .init(repeating: [], count: 10)
var arregloDeArreglos: [[ArregloBidimencional]] = []
var arregloDeArreglosTri: [ArregloTridimencional] = []
var arrayOfSeasonsInt: [Int] = []

SelectedShowVC

Code Block     override func viewWillAppear(_ animated: Bool) {
        arrayCast.removeAll()
        arrayCreator.removeAll()
        arrayAiringSeason.removeAll()
        arrayOfSeasonsInt.removeAll()
        arrayCreatorName.removeAll()
//        arraySeasonsEpisodes.removeAll() //# duplicate
        arregloDeArreglos.removeAll()
        //#↓ Remove these
//        arraySeasonsEpisodes.removeAll()
//        arraySeasonsEpisodes2.removeAll()
//        arraySeasonsEpisodes3.removeAll()
//        arraySeasonsEpisodes4.removeAll()
//        arraySeasonsEpisodes5.removeAll()
//        arraySeasonsEpisodes6.removeAll()
//        arraySeasonsEpisodes7.removeAll()
//        arraySeasonsEpisodes8.removeAll()
//        arraySeasonsEpisodes9.removeAll()
//        arraySeasonsEpisodes10.removeAll()
        arrayOfArraySeasonsEpisodes = .init(repeating: [], count: 10) //#<- Use Array (of Array)
        //...
        UI.tvTitleLabel.text = UI.SelectedNamee
        UI.descriptionTV.text = UI.SelectedOverVieww
        UI.scoreLabel.text = UI.SelectedVotee
    }

(As modest as possible, your code is sort of a showcase of bad practices. Especially, getCastInfo and getCreators (with included getSeasons) are critically bad and you should better re-write them as soon as possible if your code is not just an exercise. But this is another issue.)

NumberOfSeasonsCell

Code Block //#↓ Extension to use `tag` of collection view as `season`
extension NumberOfSeasonsCell {
    func setCollectionViewTag(_ tag: Int) {
        self.seasonsCollectionView.tag = tag
    }
}

And, sorry, I have missed to post some parts (core parts) of code needed:

            cell.model = arreglo
            return cell
        }
    }

Code Block     func getSeasons(url: String) {
        //...
                    for category in toneCategories {
                        //#↓ You can simplify many `if`s using Array
                        if (1...10) ~= season {
                            let show = Episodess(dictionary: category, seasonInt: season)
                            arrayOfArraySeasonsEpisodes[season-1].append(show)
                        }
                    }
        //...

Accepted Answer

What you need to do is populate both the tableViewCell and the collection inside.
The mechanism to define a dataSource is the following:

you declare the dataSource as self when you create the Collection
then, it all occurs in

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

This dataSource function is defined in the class (which corresponds to the self above).

So, when you create the tableView cell, you have to declare dataSource for the CollectionView

Code Block    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
	seasonsCollectionView.dataSource = self

Now, in

Code Block collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath)

you need to use the correct part of the array that contains all collections.
Something like

Code Block  cell.seasonsCollectionView.model = // Something

the model should be of type episodess
So, probably coming from a 2 dimension array of episodess, that correspond to:

the tableView cell row (contained in its tag ?) where the collection is : that should give an array of episodess
in this array, the episodess for the cellForItemAt indexPath.row

Hope that helps.
