Issue with unwrapping [String] when using image cache

To fix the issue you can do You're actually force-unwrapping allValues as [String] so then there is nothing to downcast. Also change type from array of strings to single string
So instead of this in optional-binding
code :
as! [String]
as? String
if let avatarImageUrlString = self.chatVC?.avatarDictionary.allValues[indexPath.row] as? String, let imageUrl = URL(string: avatarImageUrlString) {

should help you out Sorry my bad, I didnot read the question properly.
This behaviour is because of the expires header of the response from your server. After updating the image, set headers for that image to be expired. So the browser gets the updated image.
code :
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
(if update ==1)

This might help you That is because you first show the element containing the previously loaded pop1 content
code :
$('#gr-out').css({ opacity: 0.7, 'width':$(document).width(),'height':$(document).height()}).show();
$('#popup').css({'display': 'block'});
$('#popup').load("../phpHandler.php?page="+ page);
