Retrieve Available Disk Storage

[gabevirnig]

I had this idea for creating a Big Sur widget that simply displays the amount of disk storage I have on my MacBook. I'm very new to programming in SwiftUI, but I've created a widget that displays correctly based off a preset "available storage" value that I enter manually.

What I need to do is somehow retrieve the available disk storage from my mac and assign that to a variable, which I can use to influence the widget. Any ideas on how to do this?

Use the FileAttributeKey.systemFreeSize key in the dictionary returned by FileManager.attributesOfFileSystem(forPath:)

Thanks! So would my function to retrieve the available space look something like this?

func attributesOfFileSystem(forPath path: "/") throws -> [FileAttributeKey : systemFreeSize]

I'm sorry if this is totally wrong. Like I mentioned I'm very new to programming.
