How do I save multiple UIImages in FileManager - ios

Question

I'm saving the image set by the user in FileManager. Then, I gotta retrieve these images and populate a UITableView. However, how can I save multiple different images then recover it all and present on my UITableView?
The error I'm facing is that when I save the image, then I retrieve it I just got a single UIImage, instead of multiple different images. Even though I save another different image, it just got replaced instead of adding another one. So, doing this way I can't populate a UITableView, because I always get a single UIImage instead of multiple saved images.
This is the function to save the Images
func saveImage(image: UIImage) -> Bool {
let data = UIImage.pngData(image)
guard let directory = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) as NSURL else {
return false
}
do {
try data()?.write(to: (directory.appendingPathComponent("fileName2.png")?.absoluteURL)!)
return true
} catch {
print(error.localizedDescription)
return false
}
}
That's how I'm saving the UIImage
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let image = info[.originalImage] as? UIImage {
self.imagePreview.image = image
self.namePreview.text = self.textFieldNome.text
//Saving Image
let savingImage = saveImage(image: image)
print("\(savingImage)")
}
self.picker.dismiss(animated: true, completion: nil)
}
This is the function retrieve the images
func getSavedImage(named: String) -> UIImage? {
if let dir = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) {
return UIImage(contentsOfFile: URL(fileURLWithPath: dir.absoluteString).appendingPathComponent(named).path)
}
return nil
}
ViewController: That's how I'm trying to retrieve the Images
override func viewDidLoad() {
super.viewDidLoad()
if let image = getSavedImage(named: "fileName2.png") {
print(image)
}
}

Solution is here :)
import Photos
let imagesArray = [UIImage]()
for image in imagesArray{ //multiple image array
let objImage: UIImage = image
PHPhotoLibrary.shared().performChanges({
PHAssetChangeRequest.creationRequestForAsset(from:
objImage)
}, completionHandler: { success, error in
if success {
// Saved
}else {
// failed
}
})
}
