Share app link to by ActivityViewController iOS swift?

Question

My app is not Live yet. I got the app ID from the App Store Connect. I want to share the app link on social media apps. I used the UIActivityViewController:

let string1 = "itms-apps://itunes.apple.com/app/idXXXXXXX"
let url = NSURL(string: string1)

let shareItems = [UIApplication.sharedApplication().openURL(url!)]
    
let activityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
self.presentViewController(activityViewController, animated: true, completion: nil)

Problem: It is not showing some social media apps like WhatsApp.

Answer 1

This is used to open the site, not to share the app:

[UIApplication.sharedApplication().openURL(url!)]

Do this instead:

if let name = URL(string: "https://itunes.apple.com/us/app/myapp/idxxxxxxxx?ls=1&mt=8"), !name.absoluteString.isEmpty {
  let objectsToShare = [name]
  let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
  self.present(activityVC, animated: true, completion: nil)
} else {
  // show alert for not available
}
