Summary

The iOS chat UI uses fixed point fonts for assistant message text and composer text, so chat text does not reliably follow the user's iOS Larger Text / Dynamic Type setting.

Scope

This issue is intentionally scoped to chat text only:

• apps/shared/OpenClawKit/Sources/OpenClawChatUI/ChatMessageViews.swift
• apps/shared/OpenClawKit/Sources/OpenClawChatUI/ChatView.swift
• apps/shared/OpenClawKit/Sources/OpenClawChatUI/ChatComposer.swift

Do not use this issue to refactor Settings, sidebar, Talk tab, command-center cards, app chrome, or other dense iOS layout surfaces.

Steps to reproduce

1. On an iPhone, enable a larger text size in iOS Settings > Accessibility > Display & Text Size > Larger Text.
2. Open the OpenClaw iOS app.
3. Open the Chat surface and view assistant message text.
4. Type into the chat composer.

Expected behavior

Chat message text and composer text should scale with the user's Dynamic Type / Larger Text setting while remaining readable and usable.

Actual behavior

Inspection of current source shows chat text uses fixed point fonts in the shared chat UI:

• Assistant message text builds Font.system(size: 14) in ChatMessageViews.swift.
• The chat intro card uses .font(.system(size: 15)) in ChatView.swift.
• The iOS composer TextField uses .font(.system(size: 15)) in ChatComposer.swift.

These fixed sizes can keep chat text visually small even when the user has enlarged iOS text.

Logs, screenshots, and evidence

Relevant source evidence from current checkout:

apps/shared/OpenClawKit/Sources/OpenClawChatUI/ChatMessageViews.swift
  ChatAssistantTextBody builds assistant/thinking text with Font.system(size: 14).

apps/shared/OpenClawKit/Sources/OpenClawChatUI/ChatView.swift
  ChatAssistantIntroCard uses .font(.system(size: 15)).

apps/shared/OpenClawKit/Sources/OpenClawChatUI/ChatComposer.swift
  iOS TextField composer uses .font(.system(size: 15)).

Impact and severity

Affected: iOS users who rely on Larger Text / Dynamic Type for readable chat.

Severity: Accessibility/usability bug for the primary chat workflow.

Frequency: Expected whenever the affected chat text paths render with fixed font sizes under larger system text settings.

Consequence: Chat responses and composer input can remain harder to read than the user's system accessibility preference implies.

Additional information

Likely fix direction: replace fixed chat text sizes with semantic Dynamic Type styles such as .body, .callout, or Font.system(.body, design: ...), and verify Chat message rendering plus composer input at accessibility text sizes. Keep the fix limited to chat text for this issue.
