Apple App Store submission review time vs update time I've released an app to the App Store, it's been waiting for review for about 9 days.

Upon running my own dev version I've realised I'd left a critical part out. Would it be worth waiting for release and then pushing an update or remove it and resubmit?

Will the update be processed faster than a resubmission?
Updates are generally processed faster than the first submission of an app for review, but not drastically faster. It's usually around a day shorter (5 days) compared with the average 6 or 7 days for a first submission.

Note that iOS 8 has caused an increase in submissions and a consequential increase in review times; Apple may be prioritising updates more to make apps compatible with iOS 8.
