Before submitting your app to the Apple App Store, it's essential to provide the necessary information for displaying your app in the store. To do this, access the App Vitals screen in the Publish Dashboard, where you can enter your app name and icon in the App Vitals section located in the bottom right corner. Note that the splash image, displayed when your app is loading, is not mandatory.
Next, proceed to the Store Info section and use the Apple App Store > Edit Store Info feature to describe your app on the store page. This includes setting the default language, category, and review information, specifying app permissions, adding store information, and uploading screenshots. Be sure to provide all the requested details accurately.
Once you've entered all the necessary information, click the "Save" button, and you're one step closer to publishing your app on the Apple App Store.
