Is it possible to compile with source code?

Question

Programming

There is a source code for a program written in Objective C. Can I build the program? Very necessary.
How exactly? Poke instructions :)
Or can anyone help with this?

Answer 1

The Objective-C compiler is included with GCC and is available on most major platforms.

Answer 2

Only on Mac OS, look for someone with a mac, you need Xcode, and that's it.
