I'm taking a 200 level course in college right now and I'm using my Mac to code. I was using Xcode 3.x and it was amazing and it worked really well (with some minor exceptions). When I upgraded, everything looks great but I have one problem. After compiling/building, I can't test the program at all! There's no command window or output window for me to execute or use the program! I can't submit an untested product to my professor. Does anyone know how to get this to work?
