警告メッセージ

“View Controller“ is unreachable because it has no entry points, and no identifier for runtime access via -[UIStoryboard instantiateViewControllerWithIdentifier:].

原因と対処方法

原因

ストリーボード上で定義している「View Controller」がどこからもアクセスされていないよって言っています。
使われていないViewControllerがストーリーボード上に存在しているようです。

対処方法

不要なViewControllerは削除してしまいましょう。
テスト用等で一時的に退避している場合は意図通りだと思うので、一旦無視して最終的には解決するようにしましょう。
