URL Schemes not working on macOS

Question

I'm working on an app that needs to get an authorization token from an external provider. So, I need a custom URL scheme for the redirection callback.

The redirection callback is: chirper://success.

I registered the URL Scheme in my Info.plist:

I also added the following method in my AppDelegate.swift:

func handleGetURLEvent(event: NSAppleEventDescriptor?, replyEvent: NSAppleEventDescriptor?) {
    if let aeEventDescriptor = event?.paramDescriptor(forKeyword: AEKeyword(keyDirectObject)) {
        if let urlStr = aeEventDescriptor.stringValue {
            let url = URL(string: urlStr)
            print(url)
            // do something with the URL
        }
    }
}

But when I open the redirection callback URL with Safari, this is what I get:

Safari can't open this URL because macOS doesn't recognize URLs that start with chirper:

hmmm. ok, have you followed this? https://developer.apple.com/library/archive/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Inter-AppCommunication/Inter-AppCommunication.html — albert, Jun 26 '18 at 00:55
@albert No because this documentation is for iOS right? I'm developing a macOS app — Arthur Guiot, Jun 26 '18 at 00:56
i apologize...my bad. how about this: https://css-tricks.com/create-url-scheme/ — albert, Jun 26 '18 at 01:02
@albert Doesn't work... But don't worry I have an idea to do it using another method. — Arthur Guiot, Jun 27 '18 at 00:25
@albert Instead of using URL Schemes, I’ll create a WKWebView and listen for new URLs to get the access token. I couldn’t find any other methods — Arthur Guiot, Jun 28 '18 at 03:05
once you fix it, you should post it as an answer, then accept it — albert, Jun 28 '18 at 04:49
@albert The reason why I’m not posting my answer is because I’m abandoning the idea of URL Schemes when I use a WKWebView. But thank you for your help — Arthur Guiot, Jun 28 '18 at 04:59
Try to "Clean Build Folder" and rebuild. Did help for me. Looks like this is required in some cases. — toma, Oct 30 '18 at 19:16

According to the answer to this question, the problem is the inclusion of :// in the callback URL. If you remove those, the URL should be opened. I found this was correct on macOS 10.15.5.
