短いバージョン (TLDR): CoreData を iCloud Drive 経由で iCloud と同期するように既に設定されているアプリに Ensembles を統合するための一般的な手順は何ですか? Ensembles を使用して同期プロセスを容易にする方法について混乱しています。
長いバージョン: 私は初心者のプログラマーであり、iCloud / CoreData の同期で大きな壁にぶつかりました (ここでiOS 9 CoreData / iCloud - No such document at URL を参照)。
私のアプリは、クラウド同期を除いて完璧に動作します。すべてがicloudドライブと同期するように適切に構成されています-そしてそれは99％の時間動作します-しかし、アプリをランダムに壊すエラーが発生し、コードのアップル側から来ます（「ライブラリアンが重大なエラーを返しました...」）。
データはすべて coredata (sqlite) にあり、アプリは Swift 2 でプログラムされています。
アンサンブルは、私の問題を解決するのに役立つオプションのようです。ただし、それをプロジェクトに統合する方法が完全に失われています。アプリ全体を分解するプロセスに完全に圧倒されています。必要な手順について誰かがガイダンスを提供できますか? マニュアルと github の readme は非常に詳細ですが、何をしなければならないか見失っています。圧倒的:(
それが役立つ場合、以下は私の AppDelegate ファイルです。ここで、すべての作業を行う必要があることを願っています...
