(Swift 3,4,5...) S3 Download Specific Version of File

Demonstrates how to download a file from the Amazon S3 service using the versionId query parameter.

Note: This example requires Chilkat v9.5.0.89 or later. (A problem regarding AwsSubResources w/ downloads was fixed shortly after the v9.5.0.88 release.)

func chilkatTest() {
    // This requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let http = CkoHttp()!

    http.awsAccessKey = "AWS_ACCESS_KEY"
    http.awsSecretKey = "AWS_SECRET_KEY"
    http.s3Ssl = true
    http.awsRegion = "us-east-1"
    http.awsEndpoint = "s3.amazonaws.com"
    http.awsSubResources = "versionId=x8UPzRsgskmbe55lEQvhLi25PQl2lcFH"

    var bucketName: String? = "chilkat100"
    var objectName: String? = "frenchUtf8.txt"
    var localFilePath: String? = "qa_output/frenchUtf8.txt"

    var success: Bool = http.s3_DownloadFile(bucketName, objectName: objectName, localFilePath: localFilePath)

    if success != true {
        print("\(http.lastErrorText!)")
    }
    else {
        print("File downloaded.")
    }
