Firebase Deep linking for iOS is not giving url for iOS version 9.0 and above.

[Gaurav Shishodia]

I have tried every thing but I am not able get the value of url property of FIRDynamicLink class. Although I am able to access the value of FIRDynamicLinkMatchConfidence as weak.

For integration I have followed the https://firebase.google.com/docs/dynamic-links/ios link.

But for iOS version less than 9.0 I am successfully able to access the required values.

The test dynamic link is https://wz9p3.app.goo.gl/o5yr

I am successfully able to get the required values in  https://wz9p3.app.goo.gl/apple-app-site-association. This means my app in successfully linked with the dashboard.

My implementation is as follows :

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

    NSLog(@"%@", userActivity.webpageURL);

    __weak AppDelegate *weakSelf = self;

    BOOL handled = [[FIRDynamicLinks dynamicLinks]

                    handleUniversalLink:userActivity.webpageURL

                    completion:^(FIRDynamicLink * _Nullable dynamicLink,

                                 NSError * _Nullable error) {

                        AppDelegate *strongSelf = weakSelf;

                        [strongSelf handleReceivedLink:dynamicLink];

                   }];

return handled;

}

-(void)handleReceivedLink:(FIRDynamicLink*)dynamicLink{

    NSString* urlString = [NSString stringWithFormat:@"%@",dynamicLink.url];

    NSLog(@"Extended URL : %@",urlString); // this is giving nil value

}

The urlString is giving nil value. 

Please verify and tell me what am I doing wrong as I have spent sufficient amount of on this issue.

Thanks,

Gaurav

I am facing exactly the same issue.

I'm seeing a similar issue.

Have you defined a custom URL scheme? For example (I think) a custom URL type of "com.oneAssist.oneAssist" for the first app. If you have a different one defined, you can set that up as a parameter in the dynamic link console too.

It is used in the link resolution process, and I think it might be causing the links to get dropped.

[Joe Robb]

Ian, thanks for the response.

We have, and that wasn't the issue. We passed it onto the Firebase support team and they're looking at it now. We haven't gotten a response yet though. If we hear anything back, I'll be sure to update this thread.

Hi,

We've been facing the same issue. Firebase support wrote about a week ago too that they had received multiple reports about this bug and had been investigating it. I successfully tested exactly the same implementation about a month ago so the problem appears on their side for sure.

So just to confirm - adding the custom URL scheme matching the bundle ID didn't resolve the problem for you?

[Artem Lagzdin]

No it doesn't.

The short URL is passed to the application OK, but here in the completion handler

[[FIRDynamicLinks dynamicLinks] handleUniversalLink:userActivity.webpageURL                  completion:^(FIRDynamicLink * _Nullable dynamicLink, NSError * _Nullable error) { NSLog(@"%@, dynamicLink"); }];

the dynamicLink is nil. Moreover, if we pass long URL, completion handler returns correct dynamic link. I believe that's because for long URLs the framework splits all parameters on client-side and in case of short URL it asks the Firebase server to expand the short URL.

Interesting - I was asking about the URL scheme as it is a validation step when resolving the short link, not because its used in actually receiving the link. 

Would you be comfortable sharing an example of a short link that isn't working? 

[Artem Lagzdin]

It works now, short URLs are resolved to dynamic links via handleUniversalLink OK.
