What files of an Xcode project should I store in version control?

Question

I'm new to Xcode and just found out that it stores a bunch of user information and other stuff in the project directory that I don't really need in version control or want to put up on Github. This is what an Xcode project basically looks like:

 1 AppName/
 2 ├── AppName
 3 │   ├── Base.lproj
 4 │   │   ├── LaunchScreen.xib
 5 │   │   └── Main.storyboard
 6 │   ├── Images.xcassets
 7 │   │   └── AppIcon.appiconset
 8 │   │       └── Contents.json
 9 │   ├── AppDelegate.swift
10 │   ├── Info.plist
11 │   └── ViewController.swift
12 ├── AppName.xcodeproj
13 │   ├── project.xcworkspace
14 │   │   ├── xcuserdata
15 │   │   │   └── user1.xcuserdatad
16 │   │   │       └── UserInterfaceState.xcuserstate
17 │   │   └── contents.xcworkspacedata
18 │   ├── xcuserdata
19 │   │   └── user1.xcuserdatad
20 │   │       └── xcschemes
21 │   │           ├── AppName.xcscheme
22 │   │           └── xcschememanagement.plist
23 │   └── project.pbxproj
24 └── AppNameTests
25     ├── AppNameTests.swift
26     └── Info.plist

My inclination is to just commit the AppName/ and AppNameTests/ and exclude the AppName.xcodeproj/ directory. What's the recommended way of doing this?

You'll want to use a .gitignore file to specify which files you don't want to store in GitHub.

Here is how to create the file, and here's what should go in that .gitignore file.
