Swift Requires Chilkat v11.0.0+

Transition from MailMan.FetchSingleHeader to MailMan.FetchOne

Provides instructions for replacing deprecated FetchSingleHeader method calls with FetchOne. Swift

func chilkatTest() {
    var success: Bool = false

    let mailman = CkoMailMan()!

    //  ...
    //  ...

    var numBodyLines: Int = 5
    var msgnum: Int = 1

    //  ------------------------------------------------------------------------
    //  The FetchSingleHeader method is deprecated:

    var emailObj: CkoEmail? = mailman.fetchSingleHeader(numBodyLines: numBodyLines, msgNum: msgnum)
    if mailman.lastMethodSuccess == false {
        print("\(mailman.lastErrorText!)")
        return
    }

    //  ...
    //  ...

    emailObj = nil

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

    var headerOnly: Bool = true

    let emailOut = CkoEmail()!
    success = mailman.fetchOne(headerOnly: headerOnly, numBodyLines: numBodyLines, msgNum: msgnum, email: emailOut)
    if success == false {
        print("\(mailman.lastErrorText!)")
        return
    }
