How do you prepare your iOS app for submission to the App Store Review?

I'm interested in knowing what approaches indie developers and Makers use when getting ready for the final preparation step before submitting their iOS app to Apple for App Store Review.

I'm currently working on my own app, Lina, a task management tool that automatically arranges tasks by their priority and dependencies and uses notifications to help users stick to schedule.

And while preparing my app for submission, I've noticed that reviewing only the App Store Review Guidelines is not enough. There are lots of details that may easily get overlooked.

And if you've launched any iOS apps, I'd be interested in learning your workflows.

1. AI-assisted review

Do you use ChatGPT, Claude or another AI to go through your app before submitting it? What kind of prompt or framework do you use?

For instance, do you provide your app features, permission requests and explanations, subscriptions flow, screenshots and so on to AI and let it find possible issues with the App Store Review?

2. Manual checks

What do you check manually yourself which you won't be able to rely on AI for?

3. Learning from rejections

Have any of your apps ever been rejected by Apple? If so, what was the problem that caught you off guard the most?

It is the hidden issues in App Store Review that I am particularly curious about.

I would like to develop a good pre-review submission process for Lina, but I believe that this can serve as a good general checklist before your first iOS release.

What is your own pre-review checklist?
