UINavigationControllerのLeftBarButtonItemにカスタムボタンを設置してもスワイプで戻る方法

UINavigationControllerの左側にボタンを設置すると、画面左端からのスワイプで戻る機能がOFFになってしまいます。

self.navigationController!.interactivePopGestureRecognizer?.enabled = true

としてもスワイプで戻ることはできません。

そんな時は、

ViewController.swift
class ViewController: UIViewController, UIGestureRecognizerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        // 左端スワイプで戻るために必要
        self.navigationController?.interactivePopGestureRecognizer?.delegate = self
    }

    override func viewWillDisappear(_ animated: Bool) {
        // 画面を破棄する前にdelegateを初期化
        self.navigationController?.interactivePopGestureRecognizer?.delegate = nil
    }
}

のようにすればデフォルトのinteractivePopGestureRecognizerの機能が復活します。
