Fixed : URL(string :"url string with white space") will return nil

Space contained in any URL will give you nil value if you try to user URL(string: "")

When you try to convert below string into URL it will throw you nil value because URL(string: "") will not able to handle white spaces and this is why it return you nil value 

let imageURL = "https://s3.amazonaws.com/images.goodtime.city/Profile/4e1d7331-78df-11e7-ba2f-9e34d39fd224-10/5/2018 12:19:09 PM.png"

let url = URL(string: escapedURL!)

to fix this issue you need to use :

let escapedURL = imageURL.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)

let imageURL = "https://s3.amazonaws.com/images.goodtime.city/Profile/4e1d7331-78df-11e7-ba2f-9e34d39fd224-10/5/2018 12:19:09 PM.png"

let escapedURL = imageURL.addingPercentEncoding(
