Hacking With iOS: SwiftUI Edition Course by Paul Hudson, Hacking With Swift

My personal answers to Wrap ups, Challenges, Milestones...

Project 1: WeSplit

Challenge 1: Converter

• Challenge in Day 19 from 100 Days of SwiftUI.
• Length conversion app with Apple's dedicated Unit conversion functionality, Measurement.

Project 2: Guess the Flag

Challenge 1&2	Challenge 3

Project 3: Views and Modifiers

Go back to project 1 and use a conditional modifier to change the total amount text view to red if the user selects a 0% tip.	Go back to project 2 and replace the Image view used for flags with a new FlagImage() view that renders one flag image using the specific set of modifiers we had.	Create a custom ViewModifier (and accompanying View extension) that makes a view have a large, blue font suitable for prominent titles in a view.

Project 4: BetterRest

Challenges

Replace each VStack in our form with a Section, where the text view is the title of the section.

Replace the “Number of cups” stepper with a Picker showing the same range of values.

Change the user interface so that it always shows their recommended bedtime using a nice and large font. You should be able to remove the “Calculate” button entirely.

Project 5: Word Scramble

Challenges

Disallow answers that are shorter than three letters or are just our start word.

Add a toolbar button that calls startGame(), so users can restart with a new word whenever they want to.

Put a text view somewhere so you can track and show the player’s score for a given root word. How you calculate score is down to you, but something involving number of words and their letter count would be reasonable.

Project 6: Animation

Challenges

When you tap a flag, make it spin around 360 degrees on the Y axis.

Make the other two buttons fade out to 25% opacity.

Add a third effect of your choosing to the two flags the user didn’t choose – maybe make them scale down? Or flip in a different direction? Experiment!

Project 7: iExpense

Challenges

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!
