    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // This example shows how to use the Chilkat socket object's connection.
    let rest = CkoRest()!
    let socket = CkoSocket()!

    // Set the certificate to be used for mutual TLS authentication
    // (i.e. sets the client-side certificate for two-way TLS authentication)
    // Note: There are other ways to set the client certificate using Chilkat.
    // For example, on Windows systems, a Chilkat certificate object could be loaded with certificate
    // pre-installed (with private key) in a Windows certificate store, and then socket.SetSslClientCert could be called.
    var success: Bool = socket.setSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx", pfxPassword: "pfxPassword")
    if success != true {
        print("\(socket.lastErrorText!)")
        return
    }

    // Note: The certificate used for the client-side of TLS mutual authentication
    // must have the associated private key available. (.pfx/.p12 files typically store both
    // the certificate and associated private key.)

    // Establish the connection using the socket object (with client certificate authentication).
    var bTls: Bool = true
    var port: Int = 443
    var maxWaitMs: Int = 5000

        print("\(socket.lastErrorText!)")

    var bAutoReconnect: Bool = true

    // Use the connection:
    success = rest.useConnection(socket, autoReconnect: bAutoReconnect)
    if success != true {
        print("\(rest.lastErrorText!)")
        return
    }

    // At this point we are connected and can make REST calls...
    // For example..
    var responseJson: String? = rest.fullRequestNoBody("GET", uriPath: "/someQuery")

        print("\(rest.lastErrorText!)")
