You can try as Muhammad says.
I suggest the following code which is very easy to maintain. Copy paste the following code to a file and try yourself.
import Foundation
import SystemConfiguration
class Network {
    // Declarations
    static let shared = Network()
    // Check has Network
    func isConnected() -> Bool  {
        var zeroAddress = sockaddr_in()
        zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress))
        zeroAddress.sin_family = sa_family_t(AF_INET)
        let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
            $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in
                SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress)
            }
        }
        var flags = SCNetworkReachabilityFlags()
        if !SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) {
            return false
        }
        let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
        let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0
        return (isReachable && !needsConnection)
    }
}
Create a swift file and put the above code on that file.
Whenever you want to check the network status just use the following code
if Network.shared.isConnected() {
   print("Network available")
} else {
   print("Not connected")
}
