Program to develop applications in CUDA over MacOS X

Hellow,
I’ve been developing applications with the CUDA libraries in Windows with the program Visual Studio. I want to know if other aplication of this kind exist for Mac Os or what is the most common program used in MacOs to develop aplications.

Thank you for all.

Xcode, it’s free:
