На этом этапе приложение должно показывать результаты теста. Поскольку я хочу, чтобы имя отображалось в другой строке / шрифтом, отличным от описания, я разделил его на две метки. На данный момент ни один ярлык не отображается. Я думаю, что эта проблема возникает из-за setUpViews и / или ограничений, но я не уверен.
