私は現在Objective-Cの使用方法を学んでおり、簡単な視覚的デバッグのためにXcodeに組み込むことにしたクラスを含む単純なプロジェクトを行っていましたが、すべてのエラーと警告を解決すると、次のようになりました。

奇妙なことに、「修正されたコード」をSublime Textに戻し、保存してから、ターミナルを介してコンパイルしました。エラーも警告もありません。
私はこれに関する他の質問のいくつかを読みました、そして解決策は常に彼らが重複した宣言を見つけたか、または彼らが重複した宣言をもたらした同じ名前の余分なファイルを持っていたということでした...私はどちらも持っていません。 ..
だから...何か助けは？
