Using: MVC, SwiftUI, Combine

Stack is a FIFO to do list inspired by the Paradox of Choice.

Current Version

It’s pretty barebones. However, it doesn’t crash, it adheres to the human interface guidelines, and its useful. Problems solved with this app include, so far:

1. Establishing focus
2. Adding things to your list with minimal distraction

I’ve actually used this app to manage todos, and it’s pretty nice to be able to open the app to a single task. Seeing a whole list is distracting and overwhelming.

Going forward, I’ll add features and keep it updated… it’s still at the first stage.

ToDo.swift

This file contains two models:

struct ToDo

Contains:

• an id to conform to Identifiable
• a title string
• a boolean called complete

class ToDoStore: ObservableObject

This has one published property, a ToDo array, and has methods for saving the array to User Defaults, checking off a ToDo, and adding a new ToDo.

ContentView.swift

In this file, I’ve got three views

ContentView

It has four properties:

1. @State var adding: Bool (true if the user is currently adding a new To Do.)

2. @EnvironmentObject var store: ToDoStore

3. var emptyState: some View

4. var body: some View

The body returns a ZStack. Always on top is an add TargetButton, aligned top & leading.

• If there’s no ToDo in the store, it returns empty state
• Otherwise, it returns the title of the ToDo in a centered Text View, and a checkmark TargetButton in the bottom trailing corner

Target Button

I’m most proud of this part. Its a customizable, reusable view that’s not too complex, but makes me feel competent in composing views. Here’s the code:

I’m proud of this because it uses things that I once only studied, like closures and calculated properties, and puts them together to be useful. Because it’s a struct, I can customize any of its properties if I’d like to. Plus, I get to use trailing closure syntax to declare its action.

CreatorModal

This is a pretty simple modal with only one view: a textfield with the onCommit property defined to create a new ToDo with the text, then add it to the store.

Going forward…

I like using this to do list because you can’t really argue with what’s on top. It makes you focus. However, it’d be nice to be able to manage the store. attach things (images, files) to a ToDo, or send ToDos to other people’s stack. I’ll keep adding to this to get experience building on existing software.
