Spawning villages minecraft pe?

I just updated the 9.0 update for minecraft POCKET edition; I was wondering about the villagers.

Do they spawn naturally - and how long does it take? I'm using my old survival world so will it still work?

Also, how long does it take for wolves to spawn? :£

Unfortunately, you need to create a new world for villages to spawn because they are made to generate with the world. I think it shouldn't take too long for wolves to spawn if you are looking in the right biome.
