One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try extending this app to make sure you fully understand what’s going on.
- Use the user’s preferred currency, rather than always using US dollars.
- Modify the expense amounts in ContentView to contain some styling depending on their value – expenses under $10 should have one style, expenses under $100 another, and expenses over $100 a third style. What those styles are depend on you.
- For a bigger challenge, try splitting the expenses list into two sections: one for personal expenses, and one for business expenses. This is tricky for a few reasons, not least because it means being careful about how items are deleted!
