How can I retrieve the metadata of PHAsset?

Question

I am getting the user selected image in PHAsset format. and I want to get the image path.

My goal is to upload the image to Firebase and based their docs, I need to have the image path.

I found from researching that I need to get the metadata of the image first and store it in local file and then I can retrieve the URL. Is it correct?

My question here is (If the above correct), how can I get the metadata of PHAsset image format?

@OzgurVatansever I came across that URL, but it didn't help me as it is too old and no longer works with swift 4 — Source, Nov 03 '17 at 16:43

If you want to retrive the image file Path from your PHAsset address then use this function:

[asset requestContentEditingInputWithOptions:[PHContentEditingInputRequestOptions new] completionHandler:^(PHContentEditingInput *contentEditingInput, NSDictionary *info) {
        NSURL *imageURL = contentEditingInput.fullSizeImageURL;
        }];

asset=PHAsset *asset
