Cannot get Universal Links to work

I know it's been asked before, and I've tried everything I can find here and in the Apple forums and in various how-to websites, but I still missing something, and I'm at my wit's end. I hope someone can spot a mistake somewhere.

I’m working with XCode 7.3.1 and iOS 9.3.2 on the iPhone 6S.

Member Center App IDs ID: com.hotelplanner.hotelplanner

App ID has Assoc. Domains enabled

Development Provisioning Profile with Assoc. Domains enabled iOS Team Provisioning Profile: com.hotelplanner.hotelplanner

My selected Debug Provisioning Profile in XCode Build Settings matches the one with App Domains enabled in the member center.

Xcode Capabilities Associated Domains Applinks:www.hotelplanner.com

Xcode entitlements

        "paths":[ "/Hotels" ]
     }
    ]
  }
}

I’ve set my iOS Deployment Target to 9.0 so should not need it signed.

The validation tool at https://search.developer.apple.com/appsearch-validation-tool, given the url www.hotelplanner.com/Hotels/2446-in-Nassau-Bahamas.html says app site association file passed. Deep link failed with ‘Could not extract required information for deep links.’

The same link in notes always opens in Safari. A long press on the link gives me no options.

myAppDelegate has application:continueUserActivity:restorationHandler implemented.

-(BOOL) application:(UIApplication*) application continueUserActivity:(nonnull NSUserActivity *)userActivity restorationHandler:(nonnull void (^)(NSArray * _Nullable))restorationHandler{

    if (userActivity.activityType == NSUserActivityTypeBrowsingWeb){ 
        NSLog(@"continueUserActivity");
    }
    return NO;
}

There are no errors in the console when I launch the app on my device.

Edited to add:
I implemented webcredentials to see if I could get any more insight, and I get an error in the callback that www.hotelplanner.com isn't in my entitlements, but it is there, and the target checkbox for it is set. Also, if I leave the first parameter NULL, so that it uses the domain from my entitlement file, I get the error 'No domain provided.'

I finally filed my first technical support assistance request with Apple and was able to get this resolved. Under Code Signing, the entries under Any SDK were empty. I deleted these entries and everything works like a charm.

I have same problem with your situation and I solved. App Search API Validation Tool(https://search.developer.apple.com/appsearch-validation-tool) from apple, I got ACTION REQUIRED Could not extract required information for deep links. Learn how to implement the recommended in Deep Link but it works.

change "paths":[ "/Hotels" ] to "paths":[ "/Hotels/*" ].

I hope it works.

I had a similar issue in the past, which appeared to be an XCode bug. I had been using the same device to test builds on prior to implementing universal links, and once I implemented them, they did not work. By uninstalling the app & reinstalling it, I was then able to get the links to work.

My assumption is that the link is created in the OS upon installation of the app.
