It's the file untracked by source control.
Question marks after a type refer to Optionals , a way in Swift which lets you indicate the possibility that a value might be absent for any type at all, without the need for special constants.
You specify optional chaining by placing a question mark ( ? ) after the optional value on which you wish to call a property, method or subscript if the optional is non- nil . This is very similar to placing an exclamation point ( ! ) after an optional value to force the unwrapping of its value.
The Project navigator displays your project's files and lets you open, add, delete, and rearrange those files. To open the Project navigator, at the top of your project window's navigator area, click the icon that resembles a file folder.
You probably did not set up your git repository properly. There are ways of adding external git repositories, but they tend not to work well for github (in my experience) and always lead to these sorts of issues.
If you want to set up a remote git repository through github on XCode these are the steps you should take.
This will definitely create a project that is under version control by a remote git repository hosted on github.
