My info.plist

<key>LSApplicationQueriesSchemes</key>

<array>

<string>telprompt</string>

</array>

This piece of code in objective c works.

NSString *phoneNumber = @"telprompt:0426155885";
    NSURL *url = [NSURL URLWithString:phoneNumber];
    if ([[UIApplication sharedApplication] canOpenURL:url]) {
        [[UIApplication sharedApplication] openURL:url];
    }

This piece of code in swift DOESTN WORK!

let urlString = "telprompt:0426155885";
let url = NSURL(fileURLWithPath: urlString);
if UIApplication.sharedApplication().canOpenURL(url) {
      UIApplication.sharedApplication().openURL(url);
}

the error say

-canOpenURL: failed for URL: "telprompt:0426155885 -- file:///" - error: "This app is not allowed to query for scheme file

They are the in the same project in 2 different controller. Im slowly migrating my code to swift.

The question is why doesnt work in Swift? and how to make it work?

Point taken. You're right that the "tel:" scheme doesn't require slashes. Sorry about that. "telprompt" is undocumented.

Anyway I think the underlying problem is the use of NSURL(fileURLWithPath:) instead of NSURL(string:).

It's not a file URL; it's a regular URL. You're using the wrong NSURL constructor. And the string you have there is not a valid URL. It is missing the slashes. URLs start with "scheme colon slash slash..."

(The forums force converting mailto: URLs to a link, so rewritten...)

URLs start with "scheme colon slash slash..."

Whether requiring double slashes or not, depends on the scheme. For example mailto: URL does not require double slashes.
