This workt for me on Swift 4

DispatchQueue.global(qos: .default).async {
    for item in filesArray {
        var fileName = item["fileName"]

        // Update the text field on the main queue
        DispatchQueue.main.async {
            fileNameExportLabel.stringValue = "Exporting \(fileName).ext"
        }
        print("Exporting \(fileName).ext")

        //--code to save the stuff goes here--
    }
}
