Images are of type NSData?

How do I convert NSData to UIImage and display in the simulator using realm.objects()?

The images are already in the Realm database as NSData?

import Foundation
import RealmSwift

class Paintings: Object, Identifiable {
    
    @objc dynamic var painting: NSData?
    @objc dynamic var descriptionText: String = ""
}

ViewController

import UIKit
import RealmSwift

let realm = try! Realm()
    
var paintings: Results<Paintings>?

override func viewDidLoad() {
    super.viewDidLoad()
    
    loadPaintings()
}

func uploadImage(image: UIImage) {
    let data = NSData(data: image.pngData()!)
    let paintings = Paintings()
    paintings.painting = data
    
    let realm = try! Realm()
    
    try! realm.write {
        realm.add(paintings)
    }
    
}

func loadPaintings() {
    paintings = realm.objects(Paintings.self)
    //Not displaying images in simulator.
    paintingsCollectionView.reloadData()
}

SwiftUI Version

ForEach(data, id: \.self) { item in 
    Image(uiImage: UIImage(data: item.image! as Data)!)
}
