TableView inside UIView doesn't show up Swift - ios

Question

I’m having a problem with embedding tableView inside a UIView. I tell you what my goal is:
My goal is to have a little tableView with 3 rows (like here - Link), now I’ve made a custom UIView with a tableView inside but for some reason it doesn’t load my data + doesn’t show anything. I must be honest I’m not sure if it is the right way of doing that, cause maybe there’s a better way of doing that, so I hope you guys can help me out.
Here's my code:
import Foundation
import UIKit
class TypeTableView: UIView, UITableViewDataSource, UITableViewDelegate {
var typesData = ["Videos","Images","Posts"]
var tableView = UITableView()
// let screenHeight = UIScreen.main.bounds.height
// let screenWidth = UIScreen.main.bounds.width
//
override init(frame: CGRect){
super.init(frame: frame)
self.backgroundColor = .red
setup()
tableView.delegate = self
tableView.dataSource = self
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
}
func setup() {
tableView = UITableView(frame: CGRect(x: 0, y: 0, width: 1000, height: 100),style: .grouped)
tableView.backgroundColor = .red
tableView.layer.cornerRadius = 10
tableView.translatesAutoresizingMaskIntoConstraints = false
tableView.topAnchor.constraint(equalTo: self.topAnchor).isActive = true
tableView.leadingAnchor.constraint(equalTo: self.leadingAnchor).isActive = true
tableView.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
tableView.trailingAnchor.constraint(equalTo: self.trailingAnchor).isActive = true
self.addSubview(tableView)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return typesData.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath as IndexPath)
cell.textLabel?.text = typesData[indexPath.row]
return cell
}
}
Here's the custom cell of the tableView(the tableView is inside the customCell):
import UIKit
class ByType: UITableViewCell {
// var typesData = ["Videos","Images","Posts"]
#IBOutlet var groupedTableView: TypeTableView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
// self.preservesSuperviewLayoutMargins = false
self.separatorInset = UIEdgeInsets(top: 0, left: 15, bottom: 0, right: 15)
self.layoutMargins = UIEdgeInsets(top: 0, left: 15, bottom: 0, right: 15)
groupedTableView.layer.cornerRadius = 5
groupedTableView.layer.masksToBounds = true;
groupedTableView.backgroundColor = .red
groupedTableView.layer.borderWidth = 0.5
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
