Firebase storage uploading from local file

func addPic(){
let imageRef = storageRef.child(“images/unknown.jpeg”)
let image = URL(string: “/Users/muhaimiemohd/Desktop/Unknown.jpeg”)

    let metadata = FIRStorageMetadata()
    metadata.contentType = "image/JPEG"
    
    imageRef.putFile(image!, metadata: metadata, completion: {(metadata,error) in
        if error == nil{
            print("succeed")
        }else{
            print(error?.localizedDescription)
        }
    })
    
}

// what is wrong with the url i added bcs when i tried to run it…the debugging keep looping without stop and the storage didnt added in firebase.
