Launching App Store from App in Swift

Just by following older answers I couldn't make it work, so here I post my complete solution:

if let url  = NSURL(string: "itms-apps://itunes.apple.com/app/id1234567890"), 
   UIApplication.shared.canOpenURL(url) {
    
  UIApplication.shared.openURL(url)
    }
}

You have too many protocols in your URL. Get rid of https: so the URL reads

itms-apps://itunes.apple.com/app/bars/id706081574

I had this problem but this code just works on the phone not simulator. So check this code:

if let url = URL(string: "itms-apps://itunes.apple.com/app/id" + APP_ID ),
    UIApplication.shared.canOpenURL(url){
    UIApplication.shared.openURL(url)
}else{
    //Just check it on phone not simulator!
    print("Can not open")
}

Use just the short "itms://".

For Swift 3 this is the snippet:

UIApplication.shared.openURL(URL(string: "itms://itunes.apple.com/app/id" + appStoreAppID)!)

I hope this helps someone.

Cheers.
