Hi everyone, i am developing my game on MAC platform at the moment.
I use C# language.

Is it possible to mix C# and Javascript language for an iOS game ?
Will the performance be the same?

And last question, which language would you recommend to start iOS project ?
Thank you for your help.

Accessing other scripts can be sometimes a bit annoying if you mix the languages.
If you already use C#, no reason to switch to UnityScript. So I would recommend C#.
