SimpleWeather

This simple app is my first pet project in iOS Development by using Swift Language. I tried to make the interface and features as user-friendly as possible. The app runs on iOS and iPadOS. The project will evolve with the different betas of Xcode.

Features

• Gets current location and Weather information for this location
• Beautiful UI design
• Ability to search for locations
• Overview of the cities [not full]
• Open to all devices

API

SimpleWeather App - uses the OpenWeather API to fetch weather datas. It uses a free API key thereby it only has a 3 hours and 5 days forecast.

Code Review

• Weather Data

struct WeatherData: Codable {
   let name: String
   let message: String?
   let main: Main
   let weather: [Weather]
   let sys: Sys
}

struct Main: Codable {
   let temp: Double
   let feels_like: Double
   let temp_min: Double
   let temp_max: Double
   let pressure: Double
   let humidity: Double
}

struct Weather: Codable {
   let id: Int
   let description: String
   let icon: String
}

struct Sys: Codable {
   let country: String
}

• Connecting API

let weatherURL = "https://api.openweathermap.org/data/2.5/weather?units=imperial&appid=[TEXT YOUR API KEY]"
   
   var delegate: WeatherManagerDelegate?
   
   func fetchWeather(cityName: String) {
       
       if cityName.contains(" ") {
           
           let cityWithSpaces = cityName.replacingOccurrences(of: " ", with: "+")
           let urlString = "\(weatherURL)&q=\(cityWithSpaces)"
           performRequest(with: urlString)
           
       } else {
           
           let urlString = "\(weatherURL)&q=\(cityName)"
           performRequest(with: urlString)
       }
   }
   
  
   
   func fetchWeather(latitude: CLLocationDegrees, longitude: CLLocationDegrees) {
       
       let urlString = "\(weatherURL)&lat=\(latitude)&lon=\(longitude)"
       performRequest(with: urlString)
   }

• Location Manager Delegate

@IBAction func locationButtonPressed(_ sender: UIButton) {
       
       print("Location button pressed")
       
       locationManager.requestWhenInUseAuthorization()
       locationManager.startUpdatingLocation()
       locationManager.requestLocation()
   }
   
   func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
       
       if let location = locations.last {
           locationManager.stopUpdatingLocation()
           let lat = location.coordinate.latitude
           let lon = location.coordinate.longitude
           weatherManager.fetchWeather(latitude: lat, longitude: lon)
       }
   }
   
   func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
       
       print("Error: \(error)")
   }

Installation

Requirements

• Xcode 13+ with an iOS 13.0+ simulator
• An OpenWeatherMap API key

Installation steps

1. Clone the repo: git clone https://github.com/manste1n/simpleweather_app
2. Add a Constants.swift file in the root folder of your project (same folder with Info.plist, Assets.xcassets, etc)
3. Add the OpenWeatherMap API key and URL
