NSLayoutConstraint.activate([ viewController.view.topAnchor.constraint(equalTo: view.topAnchor), viewController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor), viewController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor), viewController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor) ]) ^ 前からこう でこれが合わないので私は NSLayoutConstraint.activate([ viewController.view.topAnchor.constraint(equalTo: view.topAnchor), viewController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor), viewController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor), viewController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor)]) こう書きます。
