TabPageViewControllerでスワイプ動作時のdelegate

swift: 3
xcode: 8.3.1
TabPageViewController: 0.2.7

TabPageViewControllerを使ってスワイプ動作時のデリゲートメソッドを利用したいのですが動きません。ヒントだけでもご教示いただければ幸いです。

swift
1import UIKit
2import TabPageViewController

4class TabStripViewController: UIViewController, UIPageViewControllerDelegate {
5    
6    override func viewDidLoad() {
7        super.viewDidLoad()
8        
9        // TabPageViewController
10        let tc = TabPageViewController.create()
11        tc.delegate = self
12        
13        let vc01 = SaleDetailItemFeedViewController(categoryInfo: "A")
14        let vc02 = SaleDetailItemFeedViewController(categoryInfo: "B")
15        let vc03 = SaleDetailItemFeedViewController(categoryInfo: "C")
16        let vc04 = SaleDetailItemFeedViewController(categoryInfo: "D")
17        
18        tc.tabItems = [
19            (vc01, vc01.categoryInfo),
20            (vc02, vc02.categoryInfo),
21            (vc03, vc03.categoryInfo),
22            (vc04, vc04.categoryInfo),
23        ]
24        
25        tc.isInfinity = true
26        
27        var option = TabPageOption()
28        option.tabMargin = 20.0
29        option.isTranslucent = false
30        tc.option = option
31        
32        // viewControllerを差し替える
33        self.childViewControllers.forEach {
34            $0.view.removeFromSuperview()
35            $0.removeFromParentViewController()
36        }
37        self.view.addSubview(tc.view)
38        self.addChildViewController(tc)
39        tc.didMove(toParentViewController: self)
40        
41    }
42    
43    func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) {
44        let currentViewController = pageViewController.viewControllers?[0]
45        print("\(String(describing: currentViewController?.title)))")
46    }
47    
48}
