aws-sdk-swift-usage

Create an S3 client in Swift using try await S3Client() for auto-detected region, or build an S3Client.S3ClientConfig with a region and pass it to S3Client(config:). All operations are async, so use an async entry point like @main with static func main() async throws.

Pass region and an awsCredentialIdentityResolver to the struct config, for example S3Client.S3ClientConfig(awsCredentialIdentityResolver: resolver, region: "us-west-2"). Use StaticAWSCredentialIdentityResolver for fixed keys or STSAssumeRoleAWSCredentialIdentityResolver for role assumption.

S3ClientConfiguration and similar class-based configs are deprecated in favor of struct-based types like S3Client.S3ClientConfig. The struct configs require parameters in declaration order and region is always mandatory when creating a config.

Yes, the SDK provides paginated async sequences such as listObjectsV2Paginated. Iterate with for try await page in client.listObjectsV2Paginated(input:) and read items from each page's contents array.

Call presignedURLForGetObject on the S3 client with a GetObjectInput and an expiration in seconds. For example, pass GetObjectInput(bucket: "my-bucket", key: "file.pdf") with expiration 3600 to get a URL valid for one hour.
