小さな町のタイルをズーム 15 から 18 でダウンロードしました。期待どおりに表示されていましたが、現在は表示されません。Yosemiteでswift 2でxcode 7を使用していました。私は現在、sierraでswift 3を使用してxcode 8.1を使用しています。アップグレードの前に問題が始まったと確信していますが、戻るタイムマシンはありません。IPad 2 でアプリをテストしたかったのでアップグレードしましたが、xcode が ipad の ios と互換性がないというメッセージが表示され、xcode 8.1 を Yosemite にロードできないというメッセージが表示されたため、sierra にアップグレードしました。コードは以下です。そして、その下のコンソール出力。エラーなし
