I spent a long time searching for ways to create a quiz app and to create a way to sort through non-random questions.
The only way I was able to create was to use a series of 3 dictionaries that are key:value pairs. With 1 being the questions, 1 answers and 1 the explanations for the answers.
The app works by a user choosing true or false and the correct answer being shown then it automatically moves onto the next question. Once all questions are complete the quiz moves onto a screen that displays the summary. To do this I have created empty arrays that get appended to and then transferred into the other view controllers.
I realise my code is awful, but this has been my first major project and the code works but I want to improve my abilities and code properly.
I have attached the critical parts of the program that I believe will help justify my explanation.
