Sending Mailcore2 Plain Emails in Swift

I've recently incorporated MailCore2 into my Objective-C project, and it has worked perfectly. Now, I am in the process of transitioning the code within the app to Swift. I have successfully imported the MailCore2 API into my swift project, but I see no documentation (Google search, libmailcore.com, github) on how to turn the following working Objective-C code into Swift Code:

MCOSMTPSession *smtpSession = [[MCOSMTPSession alloc] init];
smtpSession.hostname = @"smtp.gmail.com";
smtpSession.port = 465;
smtpSession.username = @"[email protected]";
smtpSession.password = @"password";
smtpSession.authType = MCOAuthTypeSASLPlain;
smtpSession.connectionType = MCOConnectionTypeTLS;

MCOMessageBuilder *builder = [[MCOMessageBuilder alloc] init];
MCOAddress *from = [MCOAddress addressWithDisplayName:@"Matt R"
                                              mailbox:@"[email protected]"];
MCOAddress *to = [MCOAddress addressWithDisplayName:nil 
                                            mailbox:@"[email protected]"];
[[builder header] setFrom:from];
[[builder header] setTo:@[to]];
[[builder header] setSubject:@"My message"];
[builder setHTMLBody:@"This is a test message!"];
NSData * rfc822Data = [builder data];

MCOSMTPSendOperation *sendOperation = 
   [smtpSession sendOperationWithData:rfc822Data];
[sendOperation start:^(NSError *error) {
    if(error) {
        NSLog(@"Error sending email: %@", error);
    } else {
        NSLog(@"Successfully sent email!");
    }
}];

Does anyone know how to successfully send an email in Swift using this API? Thanks in advance to all who reply.

I would've added this in the comments below the answer but there are so many.

The steps in the accepted answer worked especially using the link to the special app password for your google account.

But @RoolPaap used a different bridging header then the one I did. I used #include "Mailcore.h"

I followed this youtube video

#ifndef MyProjectName_Bridging_Header_h
#define MyProjectName_Bridging_Header_h

#include "Mailcore.h"

#endif /* MyProjectName_Bridging_Header_h */

For Swift 3 just copy this

    let smtpSession = MCOSMTPSession()
    smtpSession.hostname = "smtp.gmail.com"
    smtpSession.username = "[email protected]"
    smtpSession.password = "xxxxxxx"
    smtpSession.port = 465
    smtpSession.authType = MCOAuthType.saslPlain
    smtpSession.connectionType = MCOConnectionType.TLS
    smtpSession.connectionLogger = {(connectionID, type, data) in
        if data != nil {
            if let string = NSString(data: data!, encoding: String.Encoding.utf8.rawValue){
                NSLog("Connectionlogger: \(string)")
            }
        }
    }

    let builder = MCOMessageBuilder()
    builder.header.to = [MCOAddress(displayName: "Rool", mailbox: "[email protected]")]
    builder.header.from = MCOAddress(displayName: "Matt R", mailbox: "[email protected]")
    builder.header.subject = "My message"
    builder.htmlBody = "Yo Rool, this is a test message!"

    let rfc822Data = builder.data()
    let sendOperation = smtpSession.sendOperation(with: rfc822Data!)
    sendOperation?.start { (error) -> Void in
        if (error != nil) {
            NSLog("Error sending email: \(error)")
        } else {
            NSLog("Successfully sent email!")
        }
    }

To send an image as attachment in swift just add:

    var dataImage: NSData?
    dataImage = UIImageJPEGRepresentation(image, 0.6)!
    var attachment = MCOAttachment()
    attachment.mimeType =  "image/jpg"
    attachment.filename = "image.jpg"
    attachment.data = dataImage
    builder.addAttachment(attachment)

Here's how I did it:

Step 1) Import mailcore2, I'm using cocoapods

pod 'mailcore2-ios'

Step 2) Add mailcore2 to your bridging header: Project-Bridging-Header.h

#import <MailCore/MailCore.h>

Step 3) Translate to swift

var smtpSession = MCOSMTPSession()
smtpSession.hostname = "smtp.gmail.com"
smtpSession.username = "[email protected]"
smtpSession.password = "xxxxxxxxxxxxxxxx"
smtpSession.port = 465
smtpSession.authType = MCOAuthType.SASLPlain
smtpSession.connectionType = MCOConnectionType.TLS
smtpSession.connectionLogger = {(connectionID, type, data) in
    if data != nil {
        if let string = NSString(data: data, encoding: NSUTF8StringEncoding){
            NSLog("Connectionlogger: \(string)")
        }
    }
}

var builder = MCOMessageBuilder()
builder.header.to = [MCOAddress(displayName: "Rool", mailbox: "[email protected]")]
builder.header.from = MCOAddress(displayName: "Matt R", mailbox: "[email protected]")
builder.header.subject = "My message"
builder.htmlBody = "Yo Rool, this is a test message!"

let rfc822Data = builder.data()
let sendOperation = smtpSession.sendOperationWithData(rfc822Data)
sendOperation.start { (error) -> Void in
    if (error != nil) {
        NSLog("Error sending email: \(error)")
    } else {
        NSLog("Successfully sent email!")
    }
}
