Beamer is an upload manager framework for iOS applications.

• iOS 9+
• Swift 4

• Supports background uploads.
• Saves upload status of each file, internally
• Operation based requests
• Block based implementation
• Extensive notification support for operation status
• Cancellable operations
• Supports multiple asynchronous uploads

Beamer is an AWS based upload manager, so you have to get AWS credentials and create a model for it.

Beamer has dependency for AWSS3 library to use AWS's core functionalities.

Beamer uses CocoaPods, a library dependency management tool for iOS projects. Implementing Beamer into your project is as simple as adding the following line to your Podfile,

pod 'Beamer'

Then, run pod install in your project directory.

Make sure to use the .xcworkspace file from now on.

Beamer has dependency AWSS3 so, you should provide AWSCredentialPermissionS3 and AWSCredential otherwise library will give fatal error.

AWSCredentialPermissionS3(bucketName: String,
    uploadPath: String,
    regionName: String)

AWSCredential(regionType: AWSRegionType,
    permission: AWSCredentialPermissionS3,
    identityPoolID: String,
    token: String,
    identityID: String,
    providerName: String)

After providing AWSCredential you need to register it on AppDelegate.swift's application(_:didFinishLaunchingWithOptions:) method

func application(_ application: UIApplication,
                 didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    ...
    Beamer.shared.register(awsCredential: awsCredentialModel)
    ...
    return true
}

For creating uploadable items, you need to conform Uploadable protocol for UploadTask.

You will append uploadable item with UploadTask class.

UploadTask(file: Uploadable,
    directoryName: String,
    fileName: String,
    identifier: Int)

Optional

If your app supports background uploads, you need to call Beamer's method on AppDelegate.swift's application(_:handleEventsForBackgroundURLSession:completionHandler:) method

func application(_ application: UIApplication,
                 handleEventsForBackgroundURLSession identifier: String,
                 completionHandler: @escaping () -> Void) {
    Beamer.shared.handleBackgroundEvents(application: application, identifier: identifier, completionHandler: completionHandler)
}

After setting up, you can upload item wherever you are.

Beamer.shared.add(uploadTask: uploadTask)

You can get upload information by adding observers. Firstly, you need to conform BeamerObserver protocol. Then add it to Beamer.

Beamer.shared.addObserver(self)

You will get callbacks

• When upload task starts:

func beamer(_ beamer: Beamer, 
            didStart uploadTask: UploadTask)

• When upload progress changes:

func beamer(_ beamer: Beamer, 
            didUpdate progress: Float,
            uploadTask: UploadTask)

• When an upload task is completed:

func beamer(_ beamer: Beamer, 
            didFinish uploadTask: UploadTask)

• When an upload task fails:

func beamer(_ beamer: Beamer, 
            didFail uploadTask: UploadTask, 
            error: Error)

You can easily remove your observer from Beamer with

Beamer.shared.removeObserver(self)
