Weather App

Introduction

This project was my first attempt at a full fledged app. Although it's far from 'full fledged,' I'm happy with how it turned out! I've recently grown in love with iOS development & swift (check out this repo). I worked on it whenever I had time between work, school, exercise, spending time with my wife, & other projects I'm working on.

If you have any tips for me, please let me know! This project is officially completed.

Technology

• Xcode

• Swift, SwiftUI, & SwiftData

• Free Weather API (API free tier allows me only 3 forecast days)

Knowledge

• Apple's Swift documentation

• Apple's SwiftUI documentation

• Corner concentricity in SwiftUI on iOS 26

• Gemini;

  • note: as a matter of principle, when learning I do not let AI write any code for me. It is only used as a tutor. I made a custom Gemini Gem called "Swift & iOS Development Tutor." Here's the instructional prompt I've written for it:

  • "You are a Swift, SwiftUI, Xcode, & iOS Development tutor. I am a college student who loves mobile development. I'm eagerly learning all of iOS Development: Swift, SwiftUI, & Xcode—I will be asking you questions. Please answer in a detailed & informative way to teach me concepts. It's important to me to learn the idiomatic ways to do things; I want to know the industry standards. If you teach me about a more obscure feature or functionality (e.g. a SwiftUI keyword that I might mistake for being a part of the Swift programming language as a whole), let me know if that feature belongs to Swift or SwiftUI. Above all else, don't just code for me. Teach me & guide me."

• Helpful YouTube videos:

  • WWDC24: Meet Swift Testing | Apple –> my introdution to Swift Testing.

  • WWDC24: Go further with Swift Testing | Apple –> to show me further capabilites.

  • Xcode 16 Debugging Tutorial for Beginners (2025)

  • Sean Allen –> Massive number of tutorial videos for Swift, SwiftUI, etc.

Goals

• [COMPLETED] Set up API service (see API info below)

• [COMPLETED] Built decodable types to map API JSON data. Consists of minimal types meant to descend the JSON hierarchy to the needed data.

• [COMPLETED] Created exstension for primary API type which decodes the key data. The exstension is a static variable which provides mock data for development & previews.

• [COMPLETED] Main page styling

  • Forecast Day page

  • .sheet view for settings & user preferences

• [COMPLETED] Implement SwiftData with UserRecord model that keeps track of Farenheit/Celsuis pref's & user's saved zipcodes.

• [COMPLETED] Utilize tasks to asynchronously fetch data upon selected zipcode change.

• [COMPLETED] Day weather data focus page

• [COMPLETED] Weather App
