How can i create new game?

Answer 1

basic is a new idea. there are also advance developers, but new ideas are valuable.

Answer 2

Open up xcode, create new project, game, and study up on Spritekit!!! That is if you want to build iOS native apps
But completely depends on what game you are trying to achieve. I would first map out what i want to create and then research the best platform to build it on (ruby, python, swift etc.)
