Getting location details from image in ios swift

Question

I am trying to get location details from image using UIImagePickerControllerReferenceURL but I found that PHAsset.fetchAssets(withALAssetURLs: [URL], options: opts) has been deprecated .Please help me in getting location details.

Can we do it using PHAssetCollection?. If so please help me

   public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
    print(info)
    let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
    selectedImage.contentMode = .scaleAspectFit
    selectedImage.image = chosenImage
    dismiss(animated:true, completion: nil)

    if let URL = info[UIImagePickerControllerReferenceURL] as? URL {
        let opts = PHFetchOptions()
        opts.fetchLimit = 1
        let assets = PHAsset.fetchAssets(withALAssetURLs: [URL], options: opts)
        let asset = assets[0]
        print(asset.location)
        // The location is "asset.location", as a CLLocation

        // ... Other stuff like dismiss omitted
    }
}

Another option is you can save image to doc directory and use that path. — Dharmesh Kheni, Dec 12 '17 at 06:21

Only solution I found so far is to use the iOS 10 code block even in iOS 11 and just ignore the UIImagePickerControllerReferenceURL deprecated message (the key still exists and works in iOS 11)

import AssetsLibrary

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    if let imageUrl = info[UIImagePickerControllerReferenceURL] as? NSURL{
        print(imageUrl.absoluteString)  //"assets-library://asset/asset.JPG?id=ED7AC36B-A150-4C38-BB8C-B6D696F4F2ED&ext=JPG"


        // access image from URL
        let assetLibrary = ALAssetsLibrary()
        assetLibrary.asset(for: imageUrl as URL! , resultBlock: { (asset: ALAsset!) -> Void in
            if let actualAsset = asset as ALAsset? {
                let assetRep: ALAssetRepresentation = actualAsset.defaultRepresentation()
                let iref = assetRep.fullResolutionImage().takeUnretainedValue()
                let image = UIImage.init(cgImage: iref)
                self.img.image = image
            }
        }, failureBlock: { (error) -> Void in
        })
    }

    dismiss(animated: true, completion: nil)
}

Hope this will help.
