Answer 1

Same code in swift

func tableView(tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
        return 100.0
    }
    func tableView(tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {

        let footerView = UIView(frame:CGRectMake(0,0,320,40))

        let loginButton = UIButton(type: .Custom)
        loginButton.setTitle("LOGIN", forState: .Normal)
        loginButton.addTarget(self, action: "loginAction", forControlEvents: .TouchUpInside)
        loginButton.setTitleColor(UIColor.whiteColor(), forState: .Normal)
        loginButton.backgroundColor = UIColor.blueColor()
        loginButton.frame = CGRectMake(0, 0, 130, 30)

        footerView.addSubview(loginButton)

        return footerView
    }

    func loginAction()
    {
        print("Hello");
    }
