        button.setTitle("Войти", for: .normal)
        button.setTitleColor(.white, for: .normal)
        button.backgroundColor = UIColor(named: "BackgroundInputColor")
        button.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .bold)
        button.layer.cornerRadius = 13
        button.layer.masksToBounds = true
        button.configuration!.contentInsets = NSDirectionalEdgeInsets(top: 2, leading: 15, bottom: 2, trailing: 15)
        button.translatesAutoresizingMaskIntoConstraints = false
        return button
    }()

        view.addSubview(loginView)
        
        loginView.translatesAutoresizingMaskIntoConstraints = false

        let trailingConstraint = loginView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -8)
        
        NSLayoutConstraint.activate([
            loginView.topAnchor.constraint(equalTo: menuView.topAnchor),
            trailingConstraint,
            loginView.heightAnchor.constraint(equalToConstant: 37)
        ])

Так в ошибке об этом все написано.
