Now choose the Arguments tab add the following into the Arguments Passed On Launch field: $ This will take care of opening Terminal when we run our app from Xcode. Untick the Debug Executable check box while you’re here.

You’ll have to navigate there manually, it’s installed in /Applications/Utilities/Terminal.app. Under Info, choose the Terminal app in the Executable drop down. By default the Run scheme should be selected (and if it isn’t, select it). Under Product, choose Scheme – Edit Scheme. However, any input you’d like the user to provide to your app can’t be provided because by default, we’re not opening a Terminal Session.

Any output from your code can be seen in the console (bottom pane, right hand side, it will automatically open). If you hit the big Play Button at the top left, Xcode will go ahead and build and run your project. Xcode will create a Hello World app by default with only a main.c or main.cpp routine. Leave all the other fields at their default and choose next to begin your coding session. On the next screen, choose C or C++ instead of Objective-C or Swift from the drop down to pick your language. You’re also invited to give your project a title and a location where you’d like it to live on your hard drive, and if you’d like to setup a local git repo for it.

Under the macOS tab, find the Command Line Tool and hit next. Start a new one under File – New Project. Let’s see how to use Xcode 8.3 for C and C++ development.Įven the shortest programmes you’ll ever write with Xcode are a project. This includes all the features we know and love, such as code completion, version control, and all the rest of it. Not only is Xcode an excellent IDE for iOS and macOS apps in both Swift and Objective-C it does just as fine a job for regular C and C++ code.
