Xcode11でiOS13のターゲットのプロジェクトを作成した場合は`SceneDelegate`や`AppDelegate`はそのままで問題ないと思います。

|

> 「ライフサイクルイベント」が発生したときは SceneDelegate か AppDelegate のどちらかのメソッドしか呼ばれない
|
|
12
|
+
iOS 13 かつ SceneDelegate が使用されている場合は SceneDelegate が
|
|
13
|
+
それ以外では AppDelegate が
|
|
14
|
+
|
|
15
|
+
となっていたので、
|
|
16
|
+
ちょっと自信がありませんが、上記の対応が必要になるのは**Xcode11でiOS12.x以下をターゲットとしたプロジェクトを作成した時**だと思います。

|

上記のエラーが出たので、
|

Xcodeの`Main Interface`を空にして、
|
|
195
|
+
info.plistの`Scene Configuration`の`Storyboard Name`の項目を削除しました。
