Can my 2D game be played on IOS if built to IOS?

Hello,

Hopefully not a stupid question but apologies if it is. I am developing a 2D game for PC and was wondering if it is built to iOS can it be run immediately or would I have to re-code the game?

Yeah, that’s the whole point of Unity :smiley:

You still would need to support different controls - input by player depending on the running platform.
And most likely optimize for mobile such as texture, shaders, materials to handle good stable fps.
