Hi @think-j

It's not a missing variable, but a (potentially) missing import. UIDevice is part of UIKit, and as such only available on iOS/iPadOS. The part this code is using: UIDevice.current.userInterfaceIdiom == .pad is only relevant on those platforms - so if you're not constraining this code to just iOS, that's likely going to be part of the problem.

I suspect if you tack on import UIKit with the import SwiftUI, you won't have any trouble for iOS and iPadOS.
