I am working on a simple SWIFT app which loads a single page app from local file. When the app is launching, I use this code:

self.webView!.loadHTMLString("<html><body>1</body></html>", baseURL:"http://www.ft.com")

It works fine and the page is displayed. But when I later trigger another code in the same view:

self.webView!.loadHTMLString("<html><body>2</body></html>", baseURL:"http://www.ft.com")

The page doesn't change at all. I checked Apple's official guide but it is very vague. Could anyone explain how loadHTMLString in more detail?

1. the webview! isn't nil? 2. do you have any delegates? – Daij-Djan Jan 06 '15 at 14:19
Also, I'm not sure the html string you wrote is valid HTML code. – Pop Flamingo Jan 06 '15 at 14:51
@TrevörAnneDenise It's valid. WebKit will display anything. – akashivskyy Jan 06 '15 at 15:40
@Daij-Djan The web view can't be nil, because the program would crash when unwrapping the optional. – akashivskyy Jan 06 '15 at 15:41
@akashivskyy right. nil. optionals. unwrapping -- sorry after objC, swift is still a bit alien. – Daij-Djan Jan 06 '15 at 15:57
The question about delegates is valid though – Daij-Djan Jan 06 '15 at 15:58
@akashivskyy Yes, WebKit will display it but for me the informations are missing. – Pop Flamingo Jan 06 '15 at 18:05

@TrevörAnneDenise Yes, you're totally right, it wouldn't pass the W3C Validation. But we're takling about a `WKWebView` here. :) – akashivskyy Jan 06 '15 at 18:11
