私はupdateDisplayメソッドを使用してアプリがクラッシュするまで動作します

Question

​​を使用してtextViewsを更新するコードでupdateDisplay()メソッドを記入するまで、すべてが画面に正しく表示されます。

DarkSky APIからアップデートする​​コードを入力する前にアプリがクラッシュすることはありませんが、アプリがクラッシュして再試行するように指示されます。

私はすべてが正しく入力されたと信じていますが、何らかの理由でアプリがその情報を受け取ることはありません。また、最近のバージョンのOkHTTPをクレードルに使用していますので、問題はそこにありません。 （許可も使用されます）

の画像は、私が使っていたButterknife形式（BindVIew）を取り除くと、このために選んだガット、すべてが動作するようになりまし追加しましたAPIから更新された情報を取得しています。
