Creating groups using a custom template xcode 8

In case this helps someone, here’s a project template that works with Xcode 12.4:

<key>Nodes</key>
<array>
    <string>ViewController.swift:comments</string>
    <string>ViewController.swift:imports:importCocoa</string>
    <string>ViewController.swift:implementation(___FILEBASENAME___: UIViewController)</string>
    <string>ViewController.swift:implementation:methods:viewDidLoad(override func viewDidLoad(\))</string>
    <string>ViewController.swift:implementation:methods:viewDidLoad:super</string>
    <string>Info.plist:UIMainStoryboardFile</string>
    <string>Info.plist:UIApplicationSceneManifest:UISceneStoryboardFile</string>
    <string>Some/MainCoordinator.swift</string>
    <string>Some/Other/TestClass.swift</string>
</array>
<key>Definitions</key>
<dict>
    <key>Some/MainCoordinator.swift</key>
    <dict>
        <key>Group</key>
        <array>
            <string>Some</string>
        </array>
        <key>Path</key>
        <string>MainCoordinator.swift</string>
    </dict>
    <key>Some/Other/TestClass.swift</key>
    <dict>
        <key>Group</key>
        <array>
            <string>Some</string>
            <string>Other</string>
        </array>
        <key>Path</key>
        <string>TestClass.swift</string>
    </dict>
</dict>

The group is Some. There’s a file inside it. There’s also a subgroup inside it called Other. And there’s a file inside Other called TestClass.

The Result
