AWS SDK for Swift code examples

Overview

The code examples in this topic show you how to use the AWS SDK for Swift with AWS.

The AWS SDK for Swift provides a Swift API for AWS infrastructure services. Using the SDK, you can build applications on top of Amazon S3, Amazon EC2, Amazon DynamoDB, and more.

Types of code examples

• Single-service actions - Code examples that show you how to call individual service functions.

• Single-service scenarios - Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

• Cross-service examples - Sample applications that work across multiple AWS services.

Find code examples

Single-service actions and scenarios are organized by AWS service in the example_code directory. A README in each folder lists and describes how to run the examples.

There are currently no cross-service examples for the AWS SDK for Swift. To request a cross-service example, create an issue in the AWS SDK Code Examples repo.

⚠️ Important

• Running this code might result in charges to your AWS account.
• Running the tests might result in charges to your AWS account.
• We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
• This code is not tested in every AWS Region. For more information, see AWS Regional Services.

Prerequisites

• You must have an AWS account, and have your default credentials and AWS Region configured as described in the Getting started section of the AWS SDK for Swift Developer Guide.
• You must have the Swift compiler (version 5.4 or later) and tools installed. If you have the latest version of Xcode installed, you already have the Swift tools. For detailed instructions, see Setting up in the AWS SDK for Swift Developer Guide.
• Some examples require newer versions of the Swift compiler. See the comment at the top of the example's Package.swift file to find the minimum Swift tools version required by the example.

To build any of these examples from a terminal window, navigate into its directory then use the command:

$ swift build

To build one of these examples in Xcode, navigate to the example's directory (such as the FindOrCreateIdentityPool directory, to build that example), then type xed . to open the example directory in Xcode. You can then use standard Xcode build and run commands.

Tests

Note: Running the tests might result in charges to your AWS account.

To run the tests for an example, use the command swift test in the example's directory.

Docker image (Beta)

This example code will soon be available in a container image hosted on Amazon Elastic Container Registry (ECR). This image will be pre-loaded with all Swift examples with dependencies pre-resolved, allowing you to explore these examples in an isolated environment.

⚠️ As of January 2023, the SDK for Swift image is available on ECR Public but is still undergoing active development. Refer to this GitHub issue for more information.
