You can save this html at DocumentDirectory as HTML file and then load that file webView. Try something like this way.

let html = "<html><img src=\"datadb/DestinationGuide/Images/Destination-Guide.png\"/> </html>"
//Save this html in `DocumentDirectory`
let saveHTML = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0].appendingPathComponent("sample.html")
try? html.data(using: .utf8)!.write(to: saveHTML)
//Now load this `sample.html` file in webView
webView.loadRequest(URLRequest(url: saveHTML))
