そのサイトがATS対応しているのかを調べる方法
背景
あれ？ WebViewで外部サイトが開かないんですけど・・もしかしてみたいな状況
やり方
nscurlコマンドというものを知った
これを使うとそのドメインのサイトがATSに対応しているか、iOS側でどういった設定をすれば通るようになるのかを教えてくれる。
nscurl --ats-diagnostics --verbose https://www.google.co.jp/
みたいに叩くと

といった感じで、TLSのver.いくつとか、暗号化スイートの設定とか、どういった設定なら通るよというのが分かってめっちゃ便利。
各設定の意味とかは公式ドキュメント
参考
教えてもらった
