// this code will be executed with in callback of 
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]).. 

let opts = PHFetchOptions()
            opts.fetchLimit = 1
            let assets = PHAsset.fetchAssets(withALAssetURLs: [URL], options: opts)
for assetIndex in 0..<assets.count {
let asset = assets[assetIndex]
                // print("Location: \(asset.location?.description) Taken: \(asset.creationDate)")
location = String(describing: asset.location!)
// Here you have the location if it found 
}
