I'm migrating a macOS application from the old and deprecated WebView to the new and sparkly WKWebView. It seems to work fine, but four error messages appear in the console (see below) just after the dialog is closed.
I searched. It seems this issue can be fixed through the addition of a target entitlement called Background Modes. This particular capability is however not listed by Xcode, so I can't add it. I think this is because we're targeting macOS and not iOS, but I'm not certain.
Stuck. Tips and advice appreciated!
