I still received an email with the subject “Final reminder: Answer the updated age ratings questions,” Is it a message relative to a specific app ? It seems it is a general reminder that does not take into account whether or not your apps are already OK.

I advise not to resubmit, that could create additional problems. Probably by this time there are a lot of submission, notably to adjust to age ratings requirement.

If all the check boxes in the 7 pages of age ratings are answered, I don't think you have to resubmit. Otherwise, yes. Can't you resubmit the same build as of August, just incrementing version and build bumber but no change to code ? You would then be safe to have all the time to complete the really ne version.

I confirm what @SgDeveloper posted. Need to submit a new release. Read support answer here: https://developer.apple.com/forums/thread/796744 And if I read correctly, a change in ratings in the future will be considered a major change that require extra process. May be exactly the same, just increment version and build and note in what's new : information about age ratings.

Received as well and do not tell which apps are concerned. This is the type of really stressful message. Looks like it was a very general email to all developers, probably for legal need.

In such a case (former rejection) it is wise to add the explanation in the message to reviewer in submission form. That helps a new reviewer to be fully aware of the context.

You don't need to submit. Just prepare for submission by completing in AppStoreConnect, but not submitting.

Please tell what is the exact size of the image you try to load (read dimensions in image file information). Is it a png image ?

You can use Preview app to resize the image at the exact dimension within resize in Tools menu.

AFAIK, you can't. See discussion here: https://stackoverflow.com/questions/55118777/re-using-the-same-bundle-id-after-permanently-app-deletion-from-the-itunesconn#:~:text=You%20can't%20delete%20and,bundle%20ID%20between%20paid%20accounts.&text=WARNING%3A%20If%20you%20remove%20an,use%20by%20another%20developer%20account.

Welcome to the forum.   I already tried to cut it into the right form Don't do so. The way to do it is to use directly screen shots of the adapted simulator. AppStoreConnect tells you what are the required sizes (other marked as optional). You only have to provide 6.9" (or 6.7") for iPhone. Select the right simulator (such as 17 Pro max) and ctrl-S in the simulator. You will get the correct format. You can provide more sizes optionnally.

If I understand your question correctly, administrativeArea in the returned CLPlacemark should give the state. Test for "TX"

You get lost when you try what ? If that may be useful, my advice is to get focused. You have learned the basics (of Swift, SwiftUI, Xcode…). Even if you are not yet an expert, that is good enough for second step. Focus: Imagine a simple app that you would be pleased to use for yourself (think of some pain points you have in your daily life that an app could help solve). Then go and develop the app. Going through all the development steps will let you put in practice what you have learned and then better understand how all this works. For sure you will face issues you cannot manage: ask for help on the forum. Once you app is completed, you will see you have learned a lot. And be ready to think of an app for the AppStore. Good luck.

Which business model? This app is free. :-) There can be a business model even if everything is free for end user. For instance, you could sell navigation information. I understand that's what the reviewer wants to checks (for whatever reason). So the best is to simply answer to questions.   how I can submit apps that get approved immediately. No way for immediately. But there is an option to request expedited review on certain circumstances. Expedited reviews You can request the review of your app to be expedited if you face extenuating circumstances, such as fixing a critical bug in your app or releasing your app to coincide with an event you’re directly associated with. Critical bug fix. When submitting an expedited review to fix a critical bug, include the steps to reproduce the bug on the current version of your app. Event-related app. For apps associated with an event, we recommend you plan and schedule the release of your app in App Store Connect. However, if your app is still in review and the launch of your event is quickly approaching, you can request to have your app review expedited. Make sure your request includes the event, date of the event, and your app’s association with the event. https://developer.apple.com/distribute/app-review/#:~:text=Submit%20an%20appeal-,Expedited%20reviews,Critical%20bug%20fix.

As Scott said, plus: there are always some bug fixes needed. Take profit of this minor release.
