なぜtableviewを追加した時、画像のような白い空白ができるのでしょうか？そしてスクロールするとcellが白い空白の上を通過します。どうすれば解決するでしょうか？アドバイスお願いします。

PagerTabStripViewController のサブクラスを storyboard で配置してますか？その際の containerView の制約はどうなってますか？

override func viewWillLayoutSubviews() { super.viewWillLayoutSubviews() let topInset = self.view.safeAreaInsets.top let width = self.view.bounds.width let height = self.view.bounds.height collectionView.frame = CGRect(x: 0, y: topInset, width: width, height: 56) scrollView.frame = CGRect(x: 0, y: topInset + 56, width: width, height: height - 56) } ストーリーボードでcontainerViewは配置しておらずこのようにコードで位置を決めています。。

うーん、再現しませんね。scrollView の作り方が違うのかな…。あと、UITabBarController の中に UINavigationController がいて、その中に PagerTabStripViewController のサブクラスがある感じでしょうか。

上記にscrollViewのところのコード載せました。。よろしくお願いします。
