Handle No Internet Connection Error Before Try to Parse the Result in Alamofire

Question

How should I handle if there is an error occurs when there is no internet connection in Alamofire. I tried checking if data is nil or not but it does not work.

Below

Answer 1

Other way to check for internet connection existing

import SystemConfiguration

func connectedToNetwork() -> Bool {

        var zeroAddress = sockaddr_in()    

       zeroAddress.sin_len = UInt8(sizeofValue(zeroAddress))

        zeroAddress.sin_family = sa_family_t(AF_INET)

      guard let defaultRouteReachability = withUnsafePointer(&zeroAddress, {
            SCNetworkReachabilityCreateWithAddress(nil, UnsafePointer($0))
        }) else {
            return false
        }
        var flags : SCNetworkReachabilityFlags = []

        if SCNetworkReachabilityGetFlags(defaultRouteReachability, &flags) == false {

            return false

        }

        let isReachable = flags.contains(.Reachable)

        let needsConnection = flags.contains(.ConnectionRequired)

        return (isReachable && !needsConnection)

    }

let hasInternet = connectedToNetwork()
