I've recently started learning Japanese through self teaching (a few different mobile apps and books, this question is spawned from using one called Memrise)
But I'm learning to say "I don't like " which is pretty straight forward, but I'm confused on the particle used (if it is a particle, I still haven't fully grasped them yet).
I'll use "I don't Like Apples" as an example, part of confusion bolded:
わたしはりんごがすきではありません
