Aws Sdk Swift Usage

This teaches Claude the current AWS SDK for Swift patterns, with a heavy emphasis on avoiding deprecated config classes. The most useful bit is the insistence on using struct-based config types like S3Client.S3ClientConfig instead of the old S3ClientConfiguration, plus reminders that config parameters must be in declaration order. It covers the essentials: async client setup, credential resolvers, waiters, pagination, and presigned URLs. If you're generating Swift code that touches AWS services, this prevents Claude from hallucinating outdated patterns or mixing up the namespace conventions for model types. The examples are short and show real method signatures.

AWS SDK for Swift

Async Code Structure

All SDK operations are async. Use @main entry point:

@main
struct Main {
    static func main() async throws {
        let client = try await S3Client()
        // ... async operations
    }
}

CRITICAL: Use Struct Config Types

NEVER use S3ClientConfiguration or DynamoDBClientConfiguration - these are DEPRECATED classes.

ALWAYS use the struct-based config types:

S3Client.S3ClientConfig (not S3ClientConfiguration)
DynamoDBClient.DynamoDBClientConfig (not DynamoDBClientConfiguration)
STSClient.STSClientConfig (not STSClientConfiguration)

Config parameters MUST be in declaration order. Region is ALWAYS required when creating a config. Check the service client source for exact order.

// CORRECT - struct config
let config = try await S3Client.S3ClientConfig(region: "us-west-2")
let client = S3Client(config: config)

// WRONG - deprecated class
// let config = try await S3Client.S3ClientConfiguration(region: "us-west-2")
