Suppose your supervisor or customer gives you a new project to work on: “I want you to start helping out on my iOS project, ‘Blocks-in-Objective-C.’ Please get a copy of the code, make these changes, test, and then check your new code into the repo. By the way, we’re using Git for source control.” Have you used Git before? Do you know it well? (Does anyone truly understand Git?) Today, I’ll show you how to accomplish that task just assigned by your supervisor or customer.
Since this is an iOS blog, I’m assuming you’ve installed Xcode and therefore Git is installed on your Mac. (If you need to install Git, click here.)
