Developing a quiz game using Swift

Within this application, I've meticulously crafted a quiz designed to test users' knowledge of capital cities. The quiz spans multiple views, each presenting a different question related to capital cities around the world. To illustrate, let's consider the initial view of the quiz. Here, users encounter a question, such as identifying the capital of British Columbia. They are presented with a user-friendly picker interface, enabling them to select their response from a list of options. Upon making a selection, the app dynamically provides feedback. If the chosen answer is incorrect, a visual cue in the form of a red cross indicates the mistake. Conversely, if the user selects the correct answer, a green checkmark appears, affirming their choice.
