 #### 問題
-アラームアプリを作成し実行したのですが、結果は"Hello, World!"としか表示されません。
+アラームアプリを作成し実行したのですが、実行しても何も表示されません。
-理由としてはcontentViewが以下のようになっているからだと思うのですが、これはどのようにすれば正しくviewが表示されるでしょうか？
+viewController.swiftを編集しなければならないのでしょうか？
-参考にしているサイトにはcontentViewをどのように編集するのかということは書いてないのです。
+参考にしているサイトには以下の4つのソースコードしかありませんので、ほかをどのようにすれば表示されるのか教えて頂けると幸いです。
