I'm try to upload file from iOS to AWS API Gateway and passthrough it to Lambda function, How can I implement this scenario?
I can use multipart/form-data to upload to AWS API Gateway but how make input Model support binary data?

Thanks For response, after a little of reading I figure out that's no way to upload file to lambda (and it's not logical because it's event based) and the only valid use case to upload to S3 and make S3 notify lambda.
I'd highly recommend using direct S3 upload using one of the AWS SDKs. AWS Lambda is suited to process just short events, not content transfers like uploads. You can check its billing and limits to make a more informed decision on if it's really something you're looking for.
API Gateway has added support for an S3 Proxy. This allows you to expose file uploading directly to S3.
