GameSalad

GameSalad is an interesting and free application that will allow you to create your own videogame without programming and in only a few hours.

Its use is as simple as dragging and dropping the elements of the game (called actors) and a series of pre-programmed codes (or rules) that will allow you to create a multitude of games of all types.

If it's hard for you to start, you just have to visit the official page, filled with tutorials on how to start to dominate the program, and the forum where the community places its projects and looks for contributors, where they will undoubtedly offer you help.

It can seem that its limited interface is too closed, but it's sure that when using a little inventiveness, its simple tools can create quite entertaining games and perfect to publish in the Apple Store.
