5-31-24: Day 99

Day 99 consisted of the wrap up chapter for project 19, its review, and 3 challenges:

SnowSeeker review

Challenge 1: Add a photo credit over the ResortView image. The data is already loaded from the JSON for this purpose, so you just need to make it look good in the UI:

Challenge 2: Fill in the loading and saving methods for Favorites:

Challenge 3: For a real challenge, let the user sort the resorts in ContentView either using the default order, alphabetical order, or country order:

4-16-24: Day 60

Day 60 consisted of another milestone and the fifth consolidation day, reviewing what I learned, key points, and a challenge to build another complete app from scratch by ourselves:

Key Points:

Custom Codable keys

Completely custom Codable implementations

Challenge: Use URLSession to download some JSON from the internet, use Codable to convert it to Swift types, then use NavigationStack, List, and more to display it to the user. Your first step should be to examine the JSON. There is an array of people, and each person has an ID, name, age, email address, and more. They also have an array of tag strings, and an array of friends, where each friend has a name and ID. At the very least you should 1) Fetch the data and parse it into User and Friend structs, 2) Display a list of users with a little information about them, such as their name and whether they are active right now, 3) Create a detail view shown when a user is tapped, presenting more information about them, including the names of their friends, and 4) Before you start your download, check that your User array is empty so that you don’t keep starting the download every time the view is shown:

I never fully grasped how to handle JSON before starting this project, and I learned so much in the past 24 hours, not only that. It taught me a lot. Tomorrow, I'll fix the date format, add the colors and designs I deemed lower priority, and review for Day 59's challenges. I interrogated the hell out of an AI, learned more in a day than I have in the past 5 days, and I'm going to sleep.

Day 60 quote: "I hope that in this year to come, you make mistakes. Because if you are making mistakes, then you are making new things, trying new things, learning, living, pushing yourself, changing yourself, changing your world. You're doing things you've never done before, and more importantly, you're doing something." - Neil Gaiman

5-27-24: Day 95

Day 95 consisted of another milestone and the seventh consolidation day, reviewing what I learned, key points, and a challenge to build another complete app from scratch by ourselves:

Key points:

Functional programming

Result

Challenge: Build an app that helps users roll dice then store the results they had. At the very least you should let users roll dice, and also let them see results from previous rolls:

This is as far as I got. It's a skeleton, but I plan to expand on it much further in the future and make it a portfolio project.

Day 95 quote: "Being challenged in life is inevitable, but being defeated is optional." - Roger Crawford

5-26-24: Day 94

Day 94 consisted of the wrap up chapter for project 18, its review, and 3 challenges:

LayoutAndGeometry review

Challenge 1: Make views near the top of the scroll view fade out to 0 opacity – I would suggest starting at about 200 points from the top:

Challenge 2: Make views adjust their scale depending on their vertical position, with views near the bottom being large and views near the top being small. I would suggest going no smaller than 50% of the regular size:

Challenge 3: For a real challenge make the views change color as you scroll. For the best effect, you should create colors using the Color(hue:saturation:brightness:) initializer, feeding in varying values for the hue:

I’m sure there’s a way I can avoid repeating "Double.random(in: 0…1)", but I didn’t spend too much time on it, and storing the values in a constant wasn’t working for some reason.

Needed a break!

5-23-24: Day 91

Day 91 consisted of the wrap up chapter for project 17, its review, and 3 challenges:

Flashzilla review

Challenge 1: When adding a card, the text fields keep their current text. Fix that so that the textfields clear themselves after a card is added:

Challenge 2: If you drag a card to the right but not far enough to remove it, then release, you see it turn red as it slides back to the center. Why does this happen and how can you fix it? (Tip: think about the way we set offset back to 0 immediately, even though the card hasn’t animated yet. You might solve this with a ternary within a ternary, but a custom modifier will be cleaner.):

Simplest solution for now.

Challenge 3: For a harder challenge: when the users gets an answer wrong, add that card back into the array so the user can try it again. Doing this successfully means rethinking the ForEach loop, because relying on simple integers isn’t enough—your cards need to be uniquely identifiable:

I made the cards conform to identifiable but got stuck on fixing the index and looked over a solution.

5-11-24: Day 85

Day 85 consisted of the wrap up chapter for project 16, its review, and 3 challenges:

1. HotProspects review

Challenge 1: Add an icon to the “Everyone” screen showing whether a prospect was contacted or not:

Challenge 2: Add an editing screen, so users can adjust the name and email address of someone they scanned previously. (Tip: Use the simple form of NavigationLink rather than navigationDestination(), to avoid your list selection code confusing the navigation link.):

A good amount of trial and error got me to this point.

Challenge 3: All users to customize the way contacted are sorted—by name or by most recent:

I was halfway through with this, but I couldn’t figure it out. I’m sure there’s a simpler way.
