Unity 3.x Game Development Essentials seems to be aimed at users new to Unity3D and gives quite a complete tour of the game engine – covering beginner’s topics like 3D game development basics and user interfaces, but also more advanced topics as ray-casting and optimization.
One of the main differences when developing for iOS, compared to PC or Mac, is that you have to be more careful when it comes to performance. The author of the other book, Unity iOS Essentials, is clearly aware of this, as the readers already get their hands dirty in the the second chapter called iOS Performance Guide.
