In case anyone is looking for a non MFMailCompose option, here's what I did to send using Gmail's SMTP servers.

1. Download a zip of this repo: https://github.com/jetseven/skpsmtpmessage
2. Drag and drop the files under SMTPLibrary into your XCode project
3. Create a new header file - MyApp-Briding-Header.h
4. Replace new header file with this:

#import "Base64Transcoder.h"
#import "HSK_CFUtilities.h"
#import "NSData+Base64Additions.h"
#import "NSStream+SKPSMTPExtensions.h"
#import "SKPSMTPMessage.h"

5. Go to Project(Targets > MyApp on the left)/Build Settings/Swift Compiler - Code Generation
6. Add path to header file under Objective-C Briding Header -> Debug (i.e. MyApp/MyApp-Bridging-Header.h
7. Go to Project/Build Phases/Compile Sources

8. Select all .m files and click enter. Type -fno-objc-arc and hit enter.

9. Use this code to send email:

var mail = SKPSMTPMessage()       
mail.fromEmail = "fromemail@gmail.com"
mail.toEmail = "tomail@gmail.com"
mail.requiresAuth = true
mail.login = "fromemail@gmail.com"
mail.pass = "password"
mail.subject = "test subject"
mail.wantsSecure = true
mail.relayHost = "smtp.gmail.com"

mail.relayPorts = [587]

var parts: NSDictionary = [
            "kSKPSMTPPartContentTypeKey": "text/plain; charset=UTF-8",
            "kSKPSMTPPartMessageKey": "test message",
]

mail.parts = [parts]

mail.send()

Hope it helps someone. I didn't want to use the MFMailCompose option because I didn't want to have to prompt the user.
