SwiftLinkPreview Never loads response from cache, am i doing it wrong?

[ShailendraKushwaha]

let slp = SwiftLinkPreview(cache: InMemoryCache())

        if let cached = slp.cache.slp_getCachedResponse(url: text) {

           success(cached)
        } else {
            // Perform preview otherwise
            slp.preview(text, onSuccess: {response in
                success(response)
            }
            , onError: {error in
    //            print(error.localizedDescription)
            })
        }

it always have to fetch response from online.

You should use url as the cached key.

if let url = self.slp.extractURL(text: textFieldText),
let cached = self.slp.cache.slp_getCachedResponse(url: url.absoluteString) { }
