How to send emails in Swift using Mailgun

I have the need to send automatic emails in a Swift project I'm working on. So far my best lead seems to be using Mailgun. (I'm open to better options if anyone has liked something else)

Swift is not listed in the Mailgun API Reference in their documentation, and I didn't see objective-c either. The only article speaking at all about his I've found is this one.

Update

I've been trying to piece together everything and this is where I've gotten so far.

I was able to get Mailgun installed via cocoapods. Using it in Swift has been kinda tricky.

I setup cocoapods with the following pod file:

target 'TestApp' do
pod 'mailgun', '~> 1.0.3'
end

target 'TestAppTests' do
end


With this podfile I was able to run pod install and set up the dependencies. Then I setup an Objective-C-Bridging Header in build settings. I used the following objective-C bridging header.

#ifndef Promises_Promises_Bridging_Header_h
#define Promises_Promises_Bridging_Header_h
#import <mailgun/Mailgun.h>
#import "testMail.h"
#endif


I was getting a linking error for awhile, but I needed to have the project opened via the workspace and I had to go to Product -> Schemes -> Edit Schemes and add the Pods-mailgun to the top of the list and then it would let me build.

Now I want to take advantage of the MailGun API. The docs say to do the following.

Mailgun *mailgun = [Mailgun clientWithDomain:@"samples.mailgun.org" apiKey:@"key-3ax6xnjp29jd6fds4gc373sgvjxteol0"];

[mailgun sendMessageTo:@"Jay Baird <jay.baird@rackspace.com>"
from:@"Excited User <someone@sample.org>"
subject:@"Mailgun is awesome!"
body:@"A unicode snowman for you! ☃"];

At this point I've answered my own question. The process isn't too terrible. Install mailgun using cocoapods. Link the objective-c code that is needed using an objective-c bridging header. Create an objective c file to house your method that will call the mailgun operation, and use it.

#import <Foundation/Foundation.h>
#import <mailgun/Mailgun.h>

@interface mailTest: NSObject
- (void) sendMail: (NSString*)email;

@end

Then in my swift code I just call:

            var test: mailTest = mailTest()
            test.sendMail("testemail@testemail.com")

Here is the mailTest header file. I created a .m file that implements the sendMail method and calls the code from the API and it works great. The only other thing that could be challenging is setting up the mailgun account and configuring your domain so that emails can be sent, but that isn't code related.
