### I would like to fix this problem.

- [ ] I will try and fix this problem on docs.flutter.dev.

Start with sites/docs/src/content/platform-integration/ios/setup.md and review the existing iOS setup guidance and related deployment links. Add or link instructions for deploying a development build to both an iOS simulator and a real iOS device, then verify the documentation renders correctly and covers both targets.
