This Swift code example will demonstrate how to delete a file from Amazon AWS S3 Bucket.

The code example below will cover:

• Configure AWSCognitoCredentialsProvider,
• Set up AWSS3DeleteObjectRequest
• Perform deleteObject() to delete a file from a bucket

For you to be able to use Amazon AWS S3 Service you will need to set up Amazon SDK for iOS and once it is done import needed libraries into your View Controller. The code below shows how to import required libraries only. Please refer to this guide on how to download and set up Amazon SDK for iOS.

Import Amazon AWS iOS SDK Required Libraries Into Your View Controller

import AWSCore
import AWSCognito
import AWSS3

Delete File From Amazon S3 Bucket. Code Example in Swift.

let credentialsProvider = AWSCognitoCredentialsProvider(
            regionType: AWSRegionType.-- USEast1,
            identityPoolId: "")
        
        let configuration = AWSServiceConfiguration(
            region: AWSRegionType.-- USEast1,
            credentialsProvider: credentialsProvider)
        AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration
        
        AWSLogger.defaultLogger().logLevel = .Verbose
        
        
        let s3Service = AWSS3.defaultS3()
        let deleteObjectRequest = AWSS3DeleteObjectRequest()
        deleteObjectRequest.bucket = "learn-swift" // bucket name
        deleteObjectRequest.key = "0.jpeg" // File name
        s3Service.deleteObject(deleteObjectRequest).continueWithBlock { (task:AWSTask) -> AnyObject? in
            if let error = task.error {
                print("Error occurred: \(error)")
                return nil
            }
            print("Bucket deleted successfully.")
            return nil
        }
