Ive been trying to figure out why my button won't perform the action I set it to. Any help would be appreciated!

The code works by sending in an action as input. I used another stack overflow linked in the code to get it but I cant quite figure out why it won't do the action. I tried setting another button in the view but it wouldn't do that action as well. Please help!

            .background(isDisabled || configuration.isPressed ? backgroundColor.opacity(0.3) : backgroundColor)
            // This is the key part, we are using both an overlay as well as cornerRadius
            .cornerRadius(6)
            .overlay(
                RoundedRectangle(cornerRadius: 6)

You've set the button action only in the preview code.

But it's a print, and prints from previews don't get channeled to the Xcode's console.

Define the action in the actual UI of your app and run it, you should see the result of the print call in the console.
