如何处理这种警告

我用过了

func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
    print("message data : \(remoteMessage.appData)")
}

   func getIPAddress() -> String {
    var address: String?
    var ifaddr: UnsafeMutablePointer<ifaddrs>? = nil
    if getifaddrs(&ifaddr) == 0 {
        var ptr = ifaddr
        while ptr != nil {
            defer { ptr = ptr?.pointee.ifa_next }

            let interface = ptr?.pointee
            let addrFamily = interface?.ifa_addr.pointee.sa_family
            if addrFamily == UInt8(AF_INET) || addrFamily == UInt8(AF_INET6) {

                // wifi = ["en0"]
                // wired = ["en2", "en3", "en4"]
                // cellular = ["pdp_ip0","pdp_ip1","pdp_ip2","pdp_ip3"]

                let name: String = String(cString: (interface!.ifa_name))
                if  name == "en0" || name == "en2" || name …
