Swift - command prompt?

Hello I just started the Swift course and was wondering if there was any kind of command prompt where you can input data just like C#. I've been programming a bit in C# some years ago, and it had the feature to view your code from a command prompt and input your own user data as the code progressed. Does Swift have any feature like that? Thanks...

Yes, Swift has a REPL(Read , Evaluate Print Loop) called a playground that can be created within the Xcode framework. File->New->Playground. You can also open up a terminal app on a mac and run "xcrun swift" which starts a REPL in the command line. As of Xcode 6.1 - typing swift in the terminal launches the REPL as well.

Hi dd710 Thanks for the answer. But i am in the playground. When in C#, you write your code and when thats done you want to execute it to see have it works. Where you can input your own data when the code waits for some input. For example if you need to calculate the area of a room and you want the user to input the height and width of the room. You understand me? :p

I'm sorry but I'm a little unclear on what you're describing, could you explain it a little more because from what your saying sounds more like the type of program that your C# example(A program that takes input from the user) is as opposed to the capabilities of Xcode and Swift.
