I struggled with this as well. You have to create the Library/Sounds directory programmatically and move your custom sound into it.

let soundsDirectoryURL = fileManager.urls(for: .libraryDirectory, in: .userDomainMask).first!.appendingPathComponent("Sounds")

//attempt to create the folder
do {
    try fileManager.createDirectory(atPath: soundsDirectoryURL.path,
                                    withIntermediateDirectories: true, attributes: nil)
} catch let error as NSError {
    print("Error: \(error.localizedDescription)")
}
