Make an Interactive App

Objective

Write an app that accepts input, processes it somehow, and shows output; the app should also make use of an array.

What you'll need to begin

• Xcode
• a copy of the Views and Controls App that has been cloned to your computer for reference while you work on this task
• the SF Symbols App installed on your computer, also for reference
• a copy of SwiftUI Views Quick Start downloaded to your computer, so you can look up examples as needed

Success criteria and exemplar

1. You have made a rough plan where you sketch out the interface, showing where input fields, controls, and output text areas will exist.

   Be sure to identify what type of structures will be used: VStack, HStack, ZStack, Slider, TextField, et cetera.

   Post a photo of this plan to Spaces before continuing to step 2.

2. Create a new project and organize it by adding a Model and Views group and deleting ContentView.

3. Create a static layout.

4. Bit by bit, convert the static layout to an interactive page that accepts user input.

5. Bit by bit, add computed properties, as needed, to process the input.

6. Bit by bit, add computed properties, as needed, to format and then show the output.

7. Make use of an array (possibly to show a history of calculations).

8. Where possible, use abstraction to elminate repetitive code.

Progress and due date

The task is due by the end of our class next Thursday, February 9, 2022.

Prior to the deadline, on Spaces :

• Share progress regularly in your private portfolio space
  • Be sure to post screenshots
  • Be sure to post the address of your GitHub remote at some point
