Beginners Question: Swift: NSMutableURLRequest

I have various beginner mistakes, which I am not capable to fix. Some help would be appreciated. Tried to google for it and read apple documentation but did not get far. Here is the code part:

import Foundation

struct StockDataManager  {

let headers = [
    "x-rapidapi-host": "yahoo-finance15.p.rapidapi.com",
    "x-rapidapi-key": "MYAPIKEY"
]

let request = NSMutableURLRequest(url: NSURL(string: "https://yahoo-finance15.p.rapidapi.com/api/yahoo/qu/quote/AAPL/financial-data")! as URL,
                                        cachePolicy: .useProtocolCachePolicy,
                                    timeoutInterval: 10.0)
    
request.httpMethod = "GET"
request.allHTTPHeaderFields = headers
    

let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
    if (error != nil) {
        print(error)
    } else {
        let httpResponse = response as? HTTPURLResponse
        print(httpResponse)
    }
})

dataTask.resume()

}

I get the follwoing errors at this point:

request.httpMethod = "GET"

And here:

dataTask.resume()

I am pretty sure this is basic understanding and sorry for that stupid simple question. Thanks in advance still for trying to help.

First of all don't use NSURL and NS(Mutable)URLRequest in Swift at all. Use the native types.

Any custom code must be run inside a function for example

struct StockDataManager  {
    func loadData(completion: @escaping (Result<Data, Error>) -> Void) {
        let headers = [
            "x-rapidapi-host": "yahoo-finance15.p.rapidapi.com",
            "x-rapidapi-key": "MYAPIKEY"
        ]
        
        var request = URLRequest(url: URL(string: "https://yahoo-finance15.p.rapidapi.com/api/yahoo/qu/quote/AAPL/financial-data")!,
                                          cachePolicy: .useProtocolCachePolicy,
                                          timeoutInterval: 10.0)
        
        request.httpMethod = "GET"
        request.allHTTPHeaderFields = headers
        
        let session = URLSession.shared
        let dataTask = session.dataTask(with: request, completionHandler: { (data, response, error) -> Void in
            if let error = error {
                completion(.failure(error))
            } else {
                let httpResponse = response as? HTTPURLResponse
                print(httpResponse)
                completion(.success(data!))
            }
        })
        dataTask.resume()
    }
}

The loadData function needs also a completion handler to process the asynchronously received data.

You cannot have code (request.httpMethod = "GET") which is not a declaration directly in struct. Embed it in a func, like this:

func setRequest() -> NSMutableURLRequest {
    let request = NSMutableURLRequest(
        url: NSURL(string: "https://yahoo-finance15.p.rapidapi.com/api/yahoo/qu/quote/AAPL/financial-data")! as URL,
        cachePolicy: .useProtocolCachePolicy,
        timeoutInterval: 10.0)
    request.httpMethod = "GET"
    request.allHTTPHeaderFields = headers
    
    return request
}
