swift - 如何在 Safari 应用程序扩展中获取事件选项卡？

Question

当我遵循 Apple 示例时，我总是得到一个 nil activeTab:

override func toolbarItemClicked(in window: SFSafariWindow) {
    // This method will be called when your toolbar item is clicked.

    window.getActiveTab(completionHandler: { (activeTab) in
        print(activeTab)
        activeTab?.getActivePage(completionHandler:  { (activePage) in
            print(activePage)
            activePage?.getPropertiesWithCompletionHandler( { (properties) in
                print(properties)
                if properties?.url != nil {
                    let urlString = properties!.url.absoluteString
                    print("URL!", urlString)
                    let videoURL = self.youtubeDl(urlString: urlString)
                    if videoURL != nil {
                        window.openTab(with: videoURL!, makeActiveIfPossible: true, completionHandler: nil)
                    }
                }
            })
        })
    })
}

是的，有一个 getActiveTab:

SFSafariApplication.getActiveWindow { (window) in
    window?.getActiveTab { (tab) in 
        tab?.getActivePage(completionHandler: { (page) in
        }
    }
}
