IOS

Modern iOS mobile app development in mid-2022 is done in Swift 5.0 and macOS 15.

Concepts

• @Binding: allows one "source of truth" with many references called bindings
• @StateObject: an object owned and mutated by its parent class
• Codable: a designation that an object can be en/decoded
• Identifiable: a designation that an object uses predictable identification (eg via an ID)

Installation

macOS Environment

An actual macOS development environment is required to build, test and publish an iPhone app. I set one up on the Matcha melange VM.

Development Environment

Primarily use XCode to do pretty much everything.

• I created my app using Apple's sample app, which mocks up a simple UI.
• I'm following a simple example to load JSON data from API.
