Sending Mailcore2 Plain Emails in Swift

Question

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

Answer 1

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 = "matt@gmail.com"
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: "itsrool@gmail.com")]
builder.header.from = MCOAddress(displayName: "Matt R", mailbox: "matt@gmail.com")
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!")
    }
} 

Note You might be needing a special app password for your google account. See https://support.google.com/accounts/answer/185833

Answer 2

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 */

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)

For Swift 3 just copy this

    let smtpSession = MCOSMTPSession()
    smtpSession.hostname = "smtp.gmail.com"
    smtpSession.username = "sanipcr7@gmail.com"
    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: "sanipcr7@gmail.com")]
    builder.header.from = MCOAddress(displayName: "Matt R", mailbox: "matt@gmail.com")
    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!")
        }
    }
