WKWebView local storage

I am trying to get local storage working with

WKWebView

I have created a small demo project. It is a Mac app that shows a window with some buttons and a

WKWebView

The three buttons show three variations of the same page: the Sticky Notes WebKit demo:

• Remote loads the Sticky Notes WebKit demo page in the

  WKWebView

  .
• Local loads the same content from a copy in the app bundle.
• Safari loads the Sticky Notes WebKit demo in your browser.

The first two do not work; the latter does.

What should happen is it should appear with one default sticky note, and an enabled New Note button will add new sticky notes.

In the Remote and Local variations, no note appears, and the New Note button is disabled, indicating that it couldn't access the local storage.

I'm hoping that I'm just doing something wrong in loading the

WKWebView

Here's my code for the Remote variation:

    WKWebViewConfiguration *config = [WKWebViewConfiguration new];

    config.websiteDataStore = [WKWebsiteDataStore defaultDataStore];

    self.webView = [[WKWebView alloc] initWithFrame:self.container.frame configuration:config];
    self.webView.autoresizingMask = NSViewWidthSizable | NSViewHeightSizable;

    [self.container addSubview:self.webView];

    NSURL *url = [NSURL URLWithString:@"https://webkit.org/demos/sticky-notes/"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
   
    [self.webView loadRequest:request];

Any assistance much appreciated!
