Я не использую раскадровку и все делаю программно.
Так что моя проблема в том, что при попытке запустить приложение на моем телефоне (этого не происходит, когда я использую симулятор в Xcode) и когда я использую следующий метод ...
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let destinationVC = ThirdViewController()
destinationVC.selectedExercise = exercises![indexPath.row]
self.navigationController?.pushViewController(destinationVC, animated: true)
}
... для перехода от UITableView к UIView, содержимое представления View нормально, но фон замораживается на секунду, прежде чем перейти к UIView.
Что вызывает это и как я могу это исправить?
Вот код для viewController, на который я перехожу.
