Current iOS app review times are any where between 4 to 6 working days.
We us #iosreviewtime to see the average apple review times. It’s pretty useful as it’s live and crowd sourced.
Note: It usually takes 12 hours or so before your app is found in search results, maybe 3 hrs before your direct link works. We have to be patient and let the app propagate on all of Apple servers to be able to get listed.
