+今回の./ios (social-app)開発の要点をまとめます。
+
+1. MITのライセンスを遵守すること、iosアプリとして出品しても問題ないようにすること
+https://raw.githubusercontent.com/bluesky-social/social-app/refs/heads/main/LICENSE
+
+2. "Bluesky"という名称を使用しないこと。アイコンの変更。リンクの変更
+
+3. selfhostでも動くこと。本来のsocial-appは動きませんので、これは不便なのでiosアプリに出品することにしました。なお、これはすでにpatchで実現しています。
