Getting location details from image in ios swift - 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
}
}

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.
