I know this was posted a few years ago, but they are very common mobs (hostile mobs are too common in PE in my opinion) So here are two things that may be the cause:

1. Your world is set on Always Day. Because they only spawn in the dark, there could very well be no dark areas. 2. Your world is on peaceful. Spiders don't spawn in peaceful.
