AwsSns is a Swift library that enables you to use Amazon Web Service Simple Notification Service (AWS SNS) with Swift. More details on this are available from the AWS SNS documentation.

This package builds with Swift Package Manager. Ensure you have installed and activated the latest Swift 5.1 tool chain.

To use AwsSns, modify the Package.swift file and add following dependency:

.package(url: "https://github.com/nikola-mladenovic/AwsSwiftSNSsdk", .branch("master"))

Then import the AwsSns library into the swift source code:

import AwsSns

The current release provides Publish functionality. First initialize the AwsSns instance with your credentials and the SNS host:

let snsClient = AwsSns(host: "https://sns.us-west-2.amazonaws.com/", accessKeyId: "593ca2ad2782e4000a586d28", secretAccessKey: "ASDI/YZZfLXLna3xEn7JTIJhyH/YZZfLXLna3xEn7JTIJhyH")

Then use the publish method of the AwsSns instance to send messages to the SNS topic or the SNS target. Message can be represented either as String or as JSON (dictionary). Example with String:

snsClient.publish(message: "Your message", topicArn: "arn:aws:sns:us-west-2:487164526243:test", completion: { success, error in
    // Do some work
    ...
})

To create an endpoint for a device and mobile app on one of the supported push notification services, such as GCM and APNS, use createPlatformEndpoint method of the AwsSns instance. The endpointArn that is returned by completion closure when using createPlatformEndpoint can then be used by the publish method to send a message to a mobile app. Example:

let token = "93SDOIFUHWIUEHF839UR0Q93JRF0W93FJ04W385U2Q0"
let platformApplicationArn = "arn:aws:sns:us-west-2:3904190132:app/test"

snsClient.createPlatformEndpoint(token: token, platformApplicationArn: platformApplicationArn) { success, endpointArn, error in
    // Do some work
    ...
}

To list the platform application objects for the supported push notification services, such as APNS and GCM, use listPlatformApplications method of the AwsSns instance. Method can return up to 100 platform application objects per call in it's completion closure. If additional objects are available after the first page results, then a nextToken string will not be nil in response object. Example:

snsClient.listPlatformApplications { (success, response, error) in
    // Do some work
    ...
}

To list the endpoint application arns for devices in a supported push notification service, such as GCM and APNS, use listEndpointsBy method of the AwsSns instance. Method can return up to 100 platform application objects per call in it's completion closure. If additional objects are available after the first page results, then a nextToken string will not be nil in response object. Example:

let platformApplicationArn = "arn:aws:sns:us-west-2:3904190132:app/test"

snsClient.listEndpointsBy(platformApplicationArn: platformApplicationArn) { (success, response, error) in
    // Do some work
    ...
}

To delete the endpoint for a device and mobile app from Amazon SNS, use deleteEndpoint method of the AwsSns instance. When you delete an endpoint that is also subscribed to a topic, then you must also unsubscribe the endpoint from the topic. Example:

let endpointArn = "arn:aws:sns:us-west-2:4834231343:endpoint/Example/a34939514-6d01-4444-3333-ffba93942"

snsClient.deleteEndpoint(endpointArn: endpointArn) { success, error in
    // Endpoint deleted
    ...
}

To retrive the endpoint attributes for a device on one of the supported push notification services, such as GCM and APNS, use getEndpointAttributes method of the AwsSns instance. Example:

let endpointArn = "arn:aws:sns:us-west-2:4834231343:endpoint/Example/a34939514-6d01-4444-3333-ffba93942"

snsClient.getEndpointAttributes(endpointArn: endpointArn) { (success, attributes, error) in
    // Do some work
    ...
}

To set the attributes for an endpoint for a device on one of the supported push notification services, such as GCM and APNS, use setEndpointAttributes method of the AwsSns instance. Example:

let endpointArn = "arn:aws:sns:us-west-2:4834231343:endpoint/Example/a34939514-6d01-4444-3333-ffba93942"
let attributes = [ "Enabled" : "false",
                   "Token" : "93SDOIFUHWIUEHF839UR0Q93JRF0W93FJ04W385U2Q0" ]

snsClient.setEndpointAttributes(endpointArn: endpointArn, attributes: attributes) { (success, error) in
    // Do some work
    ...
}
