create storyboard segue viewcontroller tabbarcontroller identifier. assign selelctedindex value of tabbarcontroller in prepareforsegue method

@ibaction func firstbtnaction(_ sender: any) {     (sender as! uibutton).tag = 0     performsegue(withidentifier: "tabbar", sender: sender) } @ibaction func secbtnaction(_ sender: any) {     (sender as! uibutton).tag = 1     performsegue(withidentifier: "tabbar", sender: sender) }  override func prepare(for segue: uistoryboardsegue, sender: any?) {     if segue.identifier == "tabbar" {         if let vc = segue.destination as? uitabbarcontroller {             vc.selectedindex = (sender as! uibutton).tag         }     } }
