How to check internet connection in alamofire?

Question

I am using below code for making HTTP request in server.Now I want to know whether it is connected to internet or not. Below is my code

  let request = Alam         


        

Answer 1

Using RequestAdapter class of alamofire and throw error when no internet connectivity

class RequestInterceptor : RequestAdapter{
func adapt(_ urlRequest: URLRequest) throws -> URLRequest {

    let reachable = NetworkReachabilityManager()?.isReachable ?? false
    if !reachable{
        throw NSError.NoInternet
    }
    var nUrlRequest = urlRequest
    // modify request if needed 
    return nUrlRequest
   }
}

extension NSError  {

static func createWithLocalizedDesription(withCode code:Int = 204,localizedDescription:String) -> NSError{
    return  NSError(domain: "", code:code, userInfo: [NSLocalizedDescriptionKey : localizedDescription])
}
static var NoInternet : NSError {
    return createWithLocalizedDesription(withCode: -1009,localizedDescription:"Please check your internet connection")
}

}

Now set the adapter to Alamofire Session Manager

let sessionManager = Alamofire.SessionManager(configuration: configuration)

sessionManager.adapter = RequestInterceptor()

Now each time when You create Alamofire Request, catch the error in DataResponse. This mechanism will act common to all request
