100-days-swift-ui's Issues

WeSplit app: Get ContentView code reviewed

Relates to https://github.com/p2635/100-days-swift-ui/blob/main/02-WeSplit/WeSplit/ContentView.swift

How does Swift know what I mean by `.currency`?

Here is the code: TextField("Amount", value: $billAmount, format: .currency(code: "GBP"))

How does Swift know what I mean by .currency?

Is there a way I can auto self-assign issues that I create?

Instead of manually clicking Assignees > assign yourself.

Apply day 23 ideas to previous projects

Try the iOS GitHub actions test feature for CI/CD

When I get to a point where I can write simple tests, I can also try this to learn CI/CD.

Similar to how I did it for https://github.com/p2635/cypress-10-fundamentals

Fix the missing files error in your time converter project

Update the main `README.md`

• Change it so the main README includes a tree structure of the files and descriptions of each
• Each folder (project) would then have its own README with more details

How do I set locale manually for iOS simulator?

Project: WeSplit App
Need: Need to be able to set locale for the test device (simulator)
Purpose: So I test the text field currency for the bill amount changes accordingly

[Bug] Simulator hangs on black screen when setting language manually

Reproduce steps:

1. Build and run the WeSplit project, it was working initially.
2. Changed language on the iPhone 14 Pro device (from US to UK English)
3. It restarted to a black screen.

or gets stuck here:

Solutions
Attempting to erase all content: going to iOS Simulator menu, and pressing "Reset Content and Settings". This worked but obviously wiped everything

Rock Paper Scissors App: Improve the look

The MVP looks horrible. Just take a look at #20 (comment)

Compiler error: Cannot use instance member 'countries' within property initializer

Cannot use instance member 'countries' within property initializer; property initializers run before 'self' is available.

How do I prune already deleted remote branches from VS Code?

https://thecitrusreport.com/questions/visual-studio-code-remove-branches-deleted-on-github-that-still-show-in-vs-code/

There is a setting for Prune on Fetch, I turned it on but it didn't work. So I just did git fetch -p and it fixed things. You can also access that from the command palette.

Rock Paper Scissors App: Chosen sign incorrectly shown on round 1

See the bottom of the image. The player has not yet selected anything, yet it says they have chosen Rock.

Guess the flag - 'Non-constant range: argument must be an integer literal'

Image:

Answer: missing id: \.self.

Explanation: Every view needs an id, so that it knows to update the view when the state of the program changes.

Time Converter App: Add conversion for temp, length and volume

https://www.hackingwithswift.com/100/swiftui/19

Which units you choose are down to you, but you could choose one of these:

Temperature conversion: users choose Celsius, Fahrenheit, or Kelvin.
Length conversion: users choose meters, kilometers, feet, yards, or miles.
Time conversion: users choose seconds, minutes, hours, or days.
Volume conversion: users choose milliliters, liters, cups, pints, or gallons.

I originally chose time, but maybe I can do them all in one??

Time Converter App: Show only relevant output unit options

Here is a start, this shows only different options (i.e. if seconds is selected as an input unit option, then seconds should not be shown for output unit option)

Mock:

if $0 != inputUnit {
  Text($0)
}

The only problem I had was not being able to do this requirement:

When user selects an input unit
Then the app auto-selects the first output unit on the list
(instead of having the previous output unit selected, which the mock above shows! You can see nothing is selected, that's the bug)

Time Converter App: Shorten the decimal places

This looks a bit ugly, maybe I should just limit it to a certain number of decimal places.
