let directoryURL = appSupportURL.appendingPathComponent("com.myCompany.myApp").appendingPathComponent("Documents")

How can the string com.myCompany.myApp obtained programmatically in Swift?

if let bundleIdentifier = Bundle.main.bundleIdentifier {
    appSupportURL.appendingPathComponent("\(bundleIdentifier)").appendingPathComponent("Documents")
}

Little explanation: Property bundleIdentifier is optional, therefore you have to safely-unwrap the value and then you won't be asked for any exclamation mark :)
