Use Cursor Agent mode for production app updates
A developer used Cursor’s Agent mode to ship a SwiftUI app update and found it more reliable than Chat for making code changes.
- What they did
- They built TaskNavi v1.2.0 in SwiftUI with Cursor AI and leaned on Composer’s Agent mode whenever they needed code edits. For each request, they attached a PRD, asked the agent to inspect the full codebase before touching anything, and told it to keep the changes simple and avoid breaking existing behavior. One example prompt was for adding multi-category task selection and surfacing those categories in the main task list.
- How it went
- The workflow helped them update and release the app, and it changed how they viewed Cursor: not just as a tool for quick MVP work, but as something they could trust for production code. They did not report hard numbers. The main drawback they mentioned was that results depend a lot on how well the prompt is written.
- Tips
- Have the agent review the whole project as soon as there is enough code to do so, not only near the end. Keep the request tightly scoped and ask for conservative changes so you can review the diff before anything ships.
Try it yourself with Cursor
In [project name], use Agent mode to make this change: [feature or bug fix]. First review the relevant codebase so you understand the current structure, then edit only the files needed. Follow KISS, avoid breaking changes, and keep the implementation conservative. If anything would require sending, publishing, deleting, or paying, stop and ask me to approve before proceeding. After the changes, run the build or tests you can, then show me a concise summary of what changed and the files touched. Do not commit, release, or submit anything until I approve the final diff.
Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
