cellForRowAt index path function not called - ios

Question

When I try to run my code, the cellForRowAtIndexPath function does not run for some reason.
The numberOfSections function works perfectly. I was thinking it was the dataSource/delegate function or a problem with the cell.
Would really appreciate finding solution to this problem.
import UIKit
class MoviesTableViewController: UITableViewController {
#IBOutlet weak var searchBar: UISearchBar!
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
MovieController.getAllMovies(name: "blue") { (sucess) in
if sucess {
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
}
tableView.reloadData()
}
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return MovieController.movies.count
}
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 148
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "movieCell", for: indexPath) as! MoviesTableViewCell
let movie = MovieController.movies[indexPath.row]
cell.movieRating.text = String(movie.vote_average)
cell.movieRating.text = movie.overview
cell.movieTitle.text = movie.title
return cell
}

Answer 1

Print Debugging
override func numberOfSections(in tableView: UITableView) -> Int {
print("Number of section called")
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
print("Number of rows in section called")
print("Movies count: ", MovieController.movies.count)
return MovieController.movies.count
}
If Number of section called not printed to console: you have issue with tableView and It's DataSource
else if Movies Count: 0: tableView datasource working well and It's your MoviewController.movies issue. Check your MovieController
For the next step I need to see MoviewController content.

Answer 2

First you don't need to make tablevew.delegate = self in UItableViewController its already known , but this not the issue
You should make sure that your datasource MovieController.movies
have data before you call , just print movies before you call
self.tableview.reloadData()

Answer 3

There are number of cases which prevent your cellForRowAt to be called.
If your array MovieController.movies has 0 objects/elements, which you have return as MovieController.movies.count in your numberOfRowsInSection.
If you have placed your UITableView in storyboard or xib and because of any reason your UITableView don't get enough height to show your content in that case also your cellForRowAt will never be called. In most of the cases the height is 0.
