get google stock price in swift

To get Google stock price in Swift, we need to fetch data from an API that provides stock price data. One such API is Alpha Vantage.

Here are the steps that we need to follow:

1. Sign up for an API key from Alpha Vantage by visiting their website.

2. Create a new Xcode project and add a networking library like Alamofire to it.

3. In your ViewController, make an API request to Alpha Vantage with your API key and the symbol of the stock that you want to fetch data for (in this case, we want to fetch data for Google, so the symbol is GOOGL).

   main.swift
   let apiKey = "YOUR_API_KEY"
   let url = "https://www.alphavantage.co/query?function=GLOBAL_QUOTE&symbol=GOOGL&apikey=\(apiKey)"
   
   Alamofire.request(url).responseJSON { response in
       if let json = response.result.value {
           print(json)
       }
   }

4. The response from the API will be in JSON format. You can create a model to parse the JSON data into Swift objects.

   main.swift
   struct Stock {
       let symbol: String
       let price: Double
   }
   
   extension Stock {
       init?(json: [String: Any]) {
           guard let symbol = json["01. symbol"] as? String,
                 let priceString = json["05. price"] as? String,
                 let price = Double(priceString) else {
               return nil
           }
   
           self.symbol = symbol
           self.price = price
       }
   }

5. After parsing the JSON, you can use the Stock object to display the stock price data in your app.

   main.swift
   if let json = response.result.value as? [String: Any] {
       if let quote = json["Global Quote"] as? [String: Any], let stock = Stock(json: quote) {
           print("Symbol: \(stock.symbol)")
           print("Price: \(stock.price)")
       }
   }

This is just a basic example of how to fetch and parse stock price data in Swift. There are other APIs that you can use, and you can also display the data in customized views and formats depending on your app's requirements.
