How long will it take for my app to be approved by Apple?

It's a good idea to allow between 10 days and 2 weeks for Apple approval just to be safe. Usually it takes around 7-10 days, but it's good to pad that estimate since we have no guarantees on how long Apple will take. 

You can also specify when you submit your app what date you would like your app to be released, assuming it is a date that takes place after it gets through the Apple pipeline. For example, if you want to plan press releases etc. around a certain date, you could submit your app and indicate the date you would like your app to be available.
