Closing a Tab from a Safari App Extension

I am having a surprisingly hard time finding a way to close a tab from a Safari App Extension.

I can open a tab with 

SFSafariApplication.getActiveWindow(completionHandler: { 
    $0?.openTab(with: url, makeActiveIfPossible: true) 
})

Yet neither the returned SFSafariTab, nor the SFSafariWindow have close() (or performClose()).

I can send a friendly message to the JS side of the extension and run window.close();, but this is limited to tabs that were also created via Javascript. Any tabs opened by the user, or target="_blank" are blocked off.

The third option seems to be the deprecated Safari JS Extension API. I have not yet succeeded in making this work, and it feels icky to invest time into such a dead end.

Solution

  • Now in safari 12.1 have facility to close current tab.

    /// Closes this tab. If this is the last tab in its window, the window is also closed.
- (void)close SF_AVAILABLE_MAC_SAFARI(12_1);
