Get macOS default browser name - LSCopyDefaultApplicationURLForContentType

I am developing a macOS application in Xcode. One of the things I need to do, is to open URLs the system default web browser. I have an alert that pops up that gives the user this option. The alert is supposed to show the name of the default web browser. However I am unable to figure out the name of the default web browser.

I have the tried the following code:

NSLog(@"%@", LSCopyDefaultApplicationURLForContentType(kUTTypeURL, kLSRolesAll, nil));

It just returns file:///Applications/Opera.app/ even though my default browser is set to Safari. Not matter what I change my default browser to (Chrome, Safari, Firefox, etc...), the above method just returns the URL for Opera browser.

How can I find out what the name of the default browser is? I know how to open URLs in the default browser, that's very easy, but getting the name of the default browser isn't.

I know this is possible because apps like Tweetbot, have an option saying "Open in Safari" which changes to whatever you default browser is.

//given a fileUrl
CFURLRef helperApplicationURL = LSCopyDefaultApplicationURLForURL((__bridge CFURLRef)fileUrl, kLSRolesAll, NULL);
    if (helperApplicationURL != NULL) {
        NSString *helperApplicationPath = [(__bridge NSURL *)helperApplicationURL path];
        NSString *helperApplicationName = [[NSFileManager defaultManager] displayNameAtPath:helperApplicationPath];
        CFRelease(helperApplicationURL);
        if ([helperApplicationName containsString:@".app"]) {
            helperApplicationName = [helperApplicationName stringByDeletingPathExtension];
        }
        return helperApplicationName;
    }

Using the accepted answer on Swift 5

var defaultBrowser: String? {
    NSWorkspace.shared.urlForApplication(toOpen: URL(string: "http://")!)
        .flatMap(Bundle.init(url:))
        .flatMap {
            $0.object(forInfoDictionaryKey: "CFBundleDisplayName") ?? $0.object(forInfoDictionaryKey: "CFBundleName")
        }.flatMap {
            $0 as? String
        }
}

You can use [[NSWorkspace sharedWorkspace] open:url] to open any URL in the default browser and [[NSWorkspace sharedWorkspace] URLForApplicationToOpenURL: url] to get the URL for the default application for a given URL.

To get the app name, try [[NSBundle bundleWithURL:appUrl] objectForInfoDictionaryKey:@"CFBundleDisplayName"] or [[NSBundle bundleWithURL:appUrl] objectForInfoDictionaryKey:@"CFBundleName"] if the first is null. If both fail, [appUrl deletingPathExtension] lastPathComponent] can be used as a last resort.

See the docs here:

Try the other LaunchServices method LSCopyDefaultApplicationURLForURL and pass the http scheme

CFURLRef httpURL = CFURLCreateWithString(kCFAllocatorDefault, CFSTR("http://"), NULL);
NSLog(@"%@", LSCopyDefaultApplicationURLForURL(httpURL, kLSRolesAll, nil));
