Transition from Email.GetSignedByCertChain to Email.LastSignerCert

Provides instructions for replacing deprecated GetSignedByCertChain method calls with LastSignerCert. Swift

func chilkatTest() {
    var success: Bool = false

    let email = CkoEmail()!

    // ...
    // ...

    // ------------------------------------------------------------------------
    // The GetSignedByCertChain method is deprecated:

    var certChainObj: CkoCertChain? = email.getSignedByCertChain()
    if email.lastMethodSuccess == false {
        print("\(email.lastErrorText!)")
        return
    }

    // ...
    // ...

    certChainObj = nil

    // ------------------------------------------------------------------------
    // Do the equivalent using LastSignerCert to get the signing certificate,
    // then build the cert chain from the signing certificate object.

    let signerCert = CkoCert()!
    success = email.lastSignerCert(index: 0, cert: signerCert)
    if success == false {
        print("\(email.lastErrorText!)")
        return
    }

    // Get the certificate chain from the signer certificate.
    let certChain = CkoCertChain()!
    success = signerCert.buildChain(certChain: certChain)
    if success == false {
        print("\(signerCert.lastErrorText!)")
        return
    }
