What's Wrong?

The message input box in the Code sessions on Claude iOS app doesn’t persist drafts. If I’m typing a message and the chat gets dismissed — by accidentally swiping away, switching apps, or backgrounding — whatever I’ve typed is silently discarded. When I return, the input is empty with no way to recover the text.

What Should Happen?

Drafts should persist locally, per conversation, until the user explicitly sends or clears them. At minimum a draft should survive: app backgrounding, swiping the chat away, navigating to another conversation and back, and the keyboard being dismissed.

Error Messages/Logs

Steps to Reproduce

1. Open the Claude iOS app and start a Code session or open a conversation.
2. Tap the input box and type a message (the longer the more painful — try a multi-paragraph prompt).
3. Without sending, do any of these:

a. Swipe the conversation away
b. Swipe up to background the app, then reopen
c. Navigate to a different conversation and come back

1. Observe: the input is empty, draft is gone.
