Spot the layering violation where the ViewModel reaches into the UI layer.

Codeswift

import UIKit

final class ProfileViewModel {
    private let service: UserService
    var nameLabel = UILabel()

    init(service: UserService) {
        self.service = service
    }

    func loadUser() {
        service.fetchUser { [weak self] user in
            self?.nameLabel.text = user.name
        }
    }
}
