how to fix "out of range error" when trying to access array filled with downloaded images from firebase storage

Forums > SwiftUI

I tried to download successfully uploaded images to storage with the code:

func retrieveAllPictures(helloid: String) async {

    let db = Firestore.firestore()
    var retrievedEventImages = [UIImage]()

    let result = try? await db.collection("events").document(helloid).getDocument()
    allPictureIDs = (result?.data()!["pictures"] as? [String])!
    var image = UIImage()

    for path in allPictureIDs {
        let storage = Storage.storage().reference()
        let fileRef = storage.child(path)

  try? await fileRef.getData(maxSize: 1 * 1024 * 1024) { data, error in
            if let error = error {
                return
            } else {
                image = UIImage(data: data!)!
               retrievedEventImages.append(image)
            }
        }
}

}

when trying to debug the code, I see that retrievedEventImages is filled with the UIImages still when trying to access the array at index 0 I get an out of range error maybe someone knows how to fix it, any help is appreciated
