func chilkatTest() {
    let cert = CkoCert()!

    // ------------------------------------------------------------------------
    // The GetCertChain method is deprecated:

    var certchainObj: CkoCertChain? = cert.getChain()
    if cert.lastMethodSuccess == false {
        print("\(cert.lastErrorText!)")
        return
    }

    // ...
    // ...

    certchainObj = nil

    // ------------------------------------------------------------------------
    // Do the equivalent using BuildCertChain.
    // Your application creates a new, empty CertChain object which is passed 
    // in the last argument and filled upon success.

    let certchainOut = CkoCertChain()!
    var success: Bool = cert.build(certchainOut)
    if success == false {
        print("\(cert.lastErrorText!)")
        return
    }
