Swift 4 Audio share with Whatsapp

Question

I would like to share audio (.mp3) file via WhatsApp. I used UIActivityViewController but it just share mp3 files link not the file. How can i share the file to WhatsApp? There is my code:

 @IBAction func playTusu(_ sender: Any) {
    let url = URL(string: "https://freesound.org/data/previews/405/405511_2731495-lq.mp3")!
    let playerItem = CachingPlayerItem(url: url)

    playerItem.delegate = self

    player = AVPlayer(playerItem: playerItem)
    player.automaticallyWaitsToMinimizeStalling = false
    player.play()

}

@IBAction func paylas(_ sender: Any) {
    let url: [Any] = ["https://freesound.org/data/previews/405/405511_2731495-lq.mp3"]
    let avc = UIActivityViewController(activityItems: url, applicationActivities: nil)
    self.present(avc, animated: true)
}


override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()

Thanks.

You need to first download your mp3 data, save it locally in your app and use UIDocumentInteractionController to share it to WhatsApp — Leo Dabus, Oct 24 '17 at 12:53

In your paylas function you are trying to share a String but it should actually be a URL. The question has also been answered here: How do I share an Audio File in an App using Swift 3?

@IBAction func paylas(_ sender: Any) {
    let url: [Any] = [audioFileURL]
    let avc = UIActivityViewController(activityItems: url, applicationActivities: nil)
    self.present(avc, animated: true)
}

Update

The question says that you have a file but you only have the URL to the audio.

As @Leo Dabus mentioned in the comments, you have to download the audio and create a file first. Have a look at this SO question Download mp3 file. You also have to wait until the audio has downloaded. Then, you can share the file. Make sure to do that on the UI / Main Thread.

You should at least mention where this info added into your answer came from – Leo Dabus Oct 24 '17 at 13:17
I did not see your comment until now. I did not mean to use your comment for my answer, sorry. :) Should I mention you or will you create your own answer? – Yannick Oct 24 '17 at 13:20
@Yannick thats not true I already deleted my comment with that link – Leo Dabus Oct 24 '17 at 13:21
Btw you need to tell OP that after downloading the data asynchronously he needs to share it from the main thread – Leo Dabus Oct 24 '17 at 13:22
I saw it before you deleted it but after I changed my answer. I'm not here to take credit for someone else's work. I'll update the answer – Yannick Oct 24 '17 at 13:25
