Opening a url is failing in Swift - ios

Question

breakpointing inside the callback and logging success shows false.
I added itms-apps to my plist: LSApplicationQueriesSchemes
and put this in my app delegate:
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
return true
}
func moreTapped() {
let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877")
if #available(iOS 10.0, *) {
UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in
})
} else {
UIApplication.shared.openURL(url! as URL)
}
}

Answer 1

You have the incorrect format for your URL, and you should use URL rather than NSURL in Swift.
This will open your developer page in the App Store app:
if let url = URL(string:"itms-apps://geo.itunes.apple.com/developer/quantum-productions/id979315877&mt=8") {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
There is no need to call canOpenURL for standard URL types such as http/s and itms.

Apple just announced the appstore.com URLs.

To create an App Store Short Link, apply the following rules to your company or app name:
Remove all whitespace
Convert all characters to lower-case
Remove all copyright (©), trademark (™) and registered mark (®)
symbols
Replace ampersands ("&") with "and"
Remove most punctuation (See Listing 2 for the set)
Replace accented and other "decorated" characters (ü, å, etc.) with
their elemental character (u, a, etc.)
Leave all other characters as-is.
Listing 2 Punctuation characters that must be removed.
!¡"#$%'()*+,-./:;<=>¿?#[]^_`{|}~
Below are some examples to demonstrate the conversion that takes
place.

According to Apple's latest document items-apps: or items: won't not work. You need to use
appStoreLink =
"https://itunes.apple.com/us/app/apple-store/id375380948?mt=8"
or
> SKStoreProductViewController
