(Swift 3,4,5...) Create MIME Containing Plain-Text

Calls SetBodyFromPlainText to load plain-text into the MIME body. Also sets the Content-Type header to "text/plain", and the Content-Transfer-Encoding to an appropriate transfer encoding based on the characters found in the text.

    // See Global Unlock Sample for sample code.

    let mime = CkoMime()!

    // Add a few header fields:
    var success: Bool = mime.addHeaderField("Description", value: "this is a test")
    success = mime.addHeaderField("MyId", value: "123")

    var textBody: String? = "This is the plain-text body"

    success = mime.setBodyFromPlainText(textBody)

    print("\(mime.getMime()!)")

    // The MIME should look like this:

    // Description: this is a test
    // MyId: 123
    // Content-Type: text/plain; 
    // Content-Transfer-Encoding: 7bit
    // 
    // This is the plain-text body

    // Note: The Content-Transfer-Encoding may be changed.
    // For example, to use "base64", do this:
    mime.encoding = "base64"

    // Show the MIME again, this time using the base64 
    // transfer encoding:
    print("\(mime.getMime()!)")

    // It should look like this:

    // Description: this is a test
    // MyId: 123
    // Content-Type: text/plain
    // Content-Transfer-Encoding: base64
