UICollectionView error when using SDWebImage - arrays

Question

I used SDWebImage and cell.Food.sd_setImage(with: URL(string: foodImage[indexPath.row])) to display the images and foodImage array contains the URL.
When I run it and got errors as below. I have no idea how to fix it and I can't found any errors about that. Does anyone know how to fix it? thanks.

Here is my code:
class MainPageController: UIViewController, UICollectionViewDelegate,UICollectionViewDataSource{
public var foodTitle = [String]()
public var foodImage = [String]()
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
collectionView.dataSource = self
collectionView.delegate = self
DispatchQueue.main.async {
collectionView.reloadData()
}
return foodImage.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! MainPageCollectionViewCell
cell.FoodTitle.text = self.foodTitle[indexPath.item]
cell.Food.sd_setImage(with: URL(string: foodImage[indexPath.row]),placeholderImage: UIImage(named: "image")) // I tried your suggestion but it still failed.
return cell
}
extension MainPageController{
public func fetchFoodList(){
let url = URL(string: "https://api.edamam.com/search?q=egg&app_id=110d8671&app_key=3f01522208d512f592625dfcd163ff5c&from=0&to=10")
let task = URLSession.shared.dataTask(with: url!){ (data, response, error) in
if error != nil{
print(error!)
}else{
if let urlContent = data{
do{
let json = try JSON(data:data!)
let recipes = json["hits"]
self.foodTitle=json["hits"].arrayValue.map{$0["recipe"]["label"].stringValue}
print(self.foodTitle)
self.foodImage = json["hits"].arrayValue.map {$0["recipe"]["image"].stringValue}
print(self.foodImage)
}
catch{
print("JSON Processing Failed")
}
}
}
}
task.resume()}}

i'm using sd_WebImage and it's working for me with following code :-
import SDWebImage
func collectionView(_ collectionView: UICollectionView, cellForItemAt
indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell",
for: indexPath) as! stackCollectionViewCell
cell.imageview.sd_setImage(with: URL(string: imageArr[indexPath.row]),
placeholderImage: UIImage(named: "image"))
return cell
}
But your error is for Thread because something is interrupting the main thread that's why this error is appear. so can you share your code.
Thanks
