    let selectAllBtn = UIButton.init(frame:CGRect(x:16, y: inviteSectionHeaderview.bounds.height/2, width:130, height:20))
    let sendButton = UIButton.init(frame:CGRect(x:inviteSectionHeaderview.bounds.width - 30, y: inviteSectionHeaderview.bounds.height/2, width:60, height:20))
    selectAllBtn.setTitle("select all/Cancel", for: .normal)
    selectAllBtn.backgroundColor = .black
    sendButton.backgroundColor = .black
    sendButton.setTitle("SEND", for: .normal)
    self.contactsTable.addSubview(inviteSectionHeaderview)
    inviteSectionHeaderview.addSubview(selectAllBtn)
    inviteSectionHeaderview.addSubview(sendButton)
    return inviteSectionHeaderview

}

You have two options:

Create your UIView in storyboard
Create programatically

Option 2

Create your UIView.

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? 
    let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: 30.0))        

    // Button1
    let button1 = UIButton(frame: CGRect(x: 15.0, y: 0, width: 100, height: 28.0)
    button1.setTitle("Button 1", for: .normal)
    button1.addTarget(self, action: #selector(selectorButton1), for: .touchUpInside)

    // Button2
    let button2 = UIButton(frame: CGRect(x: tableView.frame.width-150, y: 0, width: 150, height: 30.0))
    button2.setTitle("Button2", for: .normal)
    button2.addTarget(self, action: #selector(selectorButton2), for: .touchUpInside)
    button2.semanticContentAttribute = UIApplication.shared
        .userInterfaceLayoutDirection == .rightToLeft ? .forceLeftToRight : .forceRightToLeft

    headerView.addSubview(button1)
    headerView.addSubview(button2)
    return headerView 
}


    @objc func selectorButton1(_ sender : Any) {

    }

    @objc func selectorButton2(_ sender : Any) {

    }

In this case, you must set correctely y and x positions when create UIView(frame: CGRect()) and UIButton(frame: CGRect())

EDIT

From your code, you just need add the targets:

selectAllBtn.addTarget(self, action: #selector(selectorAllBtn), for: .touchUpInside)
sendButton.addTarget(self, action: #selector(selectorSendButton), for: .touchUpInside)

@objc func selectorAllBtn(_ sender : Any) {

}

@objc func selectorSendButton(_ sender : Any) {

}

You can try this code.

 func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        var headerView = tableView.dequeueReusableHeaderFooterView(withIdentifier: "headerView")

        if headerView == nil {
            headerView = UITableViewHeaderFooterView(reuseIdentifier: "headerView")

            let button1 = UIButton(frame: CGRect(x: 8, y: 8, width: 80, height: 40))
            button1.setTitle("Select", for: .normal)
            button1.addTarget(self, action: #selector(self.buttonAction), for: .touchUpInside)
            headerView?.addSubview(button1)

        }

        return headerView
    }

    func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 50 // set a height for header view
    }

    @objc func buttonAction(_ sender: UIButton) {
     // write your code...
    }
