Yes, it's based on isHorizontal environment:

var isHorizontal: Bool {
        if UIDevice.current.userInterfaceIdiom != .pad {
            if let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene {
                return windowScene.windows.first?.windowScene?.interfaceOrientation.isLandscape ?? true
            }
        }
        return false
    }
