WeatherApp

A simple SwiftUI app that shows a 7-day weather forecast for a typed location using OpenWeather.

Features

• Switch temperature units between °C and °F
• Search by city, address, or place name (geocoded via CoreLocation)
• Daily forecast list with icon, high/low, precipitation probability, clouds, and humidity
• Loading state and basic error handling

Tech Stack

• SwiftUI
• MVVM (ViewModel-driven rendering)
• CoreLocation (geocoding)
• URLSession (networking)
• SDWebImageSwiftUI (remote weather icons)

Requirements

• Xcode 15+ (Swift 5.9+)
• iOS 16+ target (can be adjusted in the project settings)
• OpenWeather API key

Configuration

This project reads configuration values from Info.plist which are mapped from Config.xcconfig.

1. Open WeatherApp/Config.xcconfig and set your values:

//MARK: - API Keys
OPEN_WEATHER_MAP_KEY = <your_openweathermap_api_key>
//MARK: - Server URLs
BASE_URL = https://api.openweathermap.org

2. Ensure Info.plist has the placeholders (already configured in this repo):

• OPEN_WEATHER_MAP_KEY = $(OPEN_WEATHER_MAP_KEY)
• BASE_URL = $(BASE_URL)

The app accesses these via Config to build requests.

Build & Run

• Open WeatherApp.xcodeproj in Xcode
• Select an iOS Simulator or device
• Press Run

No extra steps are required; SDWebImageSwiftUI is managed by Xcode (SPM) via the project settings.

Usage

• Launch the app
• Enter a location (e.g., "Berlin", "New York", or a full address)
• Tap the search icon
• Toggle the unit picker to switch between °C and °F

Notes

• Forecast data is fetched via OpenWeather One Call API 3.0: /data/3.0/onecall
• Only daily forecasts are requested (current/minutely/hourly/alerts excluded)
• Temperature conversion is done from Kelvin to the selected unit in ForecastViewModel

Troubleshooting

• Empty results or error: verify your API key and network connectivity
• Geocoding errors: try a more specific location string
• If icons don't load, check network access and that SDWebImageSwiftUI is properly resolved
